Abstract:
We briefly review recent low temperature scanning tunneling microscopy (STM) investigations performed in our laboratory1–5 on the self-assembly of the dipolar organic molecule 1-nitronaphthalene (NN) adsorbed on the reconstructed Au(111) surface. NN becomes chiral upon planar adsorption on the gold surface. We observe several coverage-driven structural transformations which are associated with simultaneous changes in the enantiomeric composition of the self-assembled molecular structures. At low coverages almost exclusively decamers with an 8:2 ratio of the enantiomers are formed. In a medium coverage range enantiopure one-dimensional molecular double chains prevail on the surface. Subsequently, molecules with opposite handedness are admixed until at monolayer coverage racemic one- and two-dimensional structures coexist. Modeling shows that hydrogen bonding causes the observed self-assembly. A subtle interplay between the electrostatic interactions among the molecules and their interaction with the reconstructed metal surface is the origin of the observed coverage-driven chiral phase transition in two dimensions.

Abstract:
Exploring the surface self-assembly of small molecules that act as building blocks (tectons) for complex supramolecular structures is crucial for realizing surface-supported functional molecular devices. Here, we report on the synthesis and surface self-assembly of a new pyrazine-derived molecule with pyridine pendants. Ambient scanning tunneling microscopy investigation at the solution–solid interface reveals polymorphic self-assembly of these molecules on a HOPG substrate. Two different molecular packing structures with equal distribution are observed. Detailed analysis of the STM images emphasizes the crucial role of weak intermolecular hydrogen bonding, and molecule–substrate interactions in the formation of the observed polymorphs. Such weak hydrogen bonding interactions are highly desirable for the formation of modular supramolecular architectures since they can provide sufficiently robust molecular structures and also facilitate error correction.

Abstract:
Self-assembly and directed-assembly are two very important aspects of supramolecular chemistry. As a young postgraduate student working in Canada with Tom Fyles my introduction to Supramolecular Chemistry was through the self-assembly of phospholipid membranes to form vesicles for which we were developing unimolecular and self-assembling transporter molecules. The next stage of my development as a scientist was in Japan with Seiji Shinkai where in a “Eureka” moment, the boronic acid templating unit (directed-assembly) of Wulff was combined with photoinduced electron transfer systems pioneered by De Silva. The result was a turn-on fluorescence sensor for saccharides; this simple result has continued to fuel my research to the present day. Throughout my career as well as assembling molecules, I have enjoyed bringing together researchers in order to develop collaborative networks. This is where molecules meet people resulting in assemblies worth more than the individual “molecule” or “researcher”. My role in developing networks with Japan was rewarded by the award of a Daiwa-Adrian Prize in 2013 and I was recently rewarded for developing networks with China with an Inaugural CASE Prize in 2015.

Abstract:
A series of discotic organic molecules with different substituents have been successfully synthesized. The structures of these compounds were fully characterized by 1H-NMR, FT-IR and MS. Their optical and electrical properties were investigated by means of Uv-vis absorption, fluorescence emission and cyclic voltammogram. By exploring the self-assembly behavior of different substituted discotic molecules through method of solvent exchange-evaporation, organic micro-nanostructures such as nanoparticles, nanotubes and nanorods were obtained through supramolecular self-assembly. In order to investigate the applications of these discotic organic molecules, the relationship of molecular design, structural design and material properties has been studied based on the experimental work.

Abstract:
AbstractA resorcinarene is a synthetic macrocycle consisting of four resorcinol molecules covalently linked by methylene bridges. The interannular bridges produce a cavitand that has a bowl-shaped structure. We have developed supramolecular capsules through Ag(I) or Cu(I) coordination-driven self-assembly of cavitands possessing 2,2′-bipyridyl arms in their upper rims. The self-assembled capsules accommodate various molecular guests and supramolecular assemblies possessing acetoxy groups. The host–guest chemistry of the molecular capsules has been applied in the fabrication of supramolecular polymers. This account describes recent developments in the supramolecular chemistry of resorcinarene-based coordination capsules and provides a brief history of resorcinarene-based capsules and related capsules.

Abstract:
In this paper, large-area chiral supramolecular self-assembly of 2,2’:6’,2”-terpyridine-4’-carboxylic acid (C[Formula: see text]H[Formula: see text]N3O2; Y) molecules on Cu(111) is studied using scanning tunneling microscopy (STM) and density functional theory (DFT) calculations. The basic building blocks of such a self-assembled monolayer are triangular vortex-shaped supramolecular structures containing three twisted Y molecules. Chirality is maintained and transferred from one vortex to the adjacent vortex in successive molecular domains within the same atomic terrace. The twisted Y molecule, bridging two nearest-neighbor Cu atoms, is stabilized by symmetric Cu–O bonds on the surface. The near perpendicularity of these bonds to the surface is the main reason for the formation of “standing-up” Y molecules.

Abstract:
Self-assembled biomaterials have been widely explored for real-time fluorescence imaging, imaging-guided surgery, and targeted therapy for tumors, etc. In particular, small molecule-based self-assembly has been established as a reliable strategy for cancer theranostics due to the merits of small-sized molecules, multiple functions, and ease of synthesis and modification. In this review, we first briefly introduce the supramolecular chemistry of small organic molecules in cancer theranostics. Then, we summarize and discuss advanced small molecule-based self-assembly for cancer theranostics based on three types, including peptides, amphiphilic molecules, and aggregation-induced emission luminogens. Finally, we conclude with a perspective on future developments of small molecule-based self-assembled biomaterials integrating diagnosis and therapy for biomedical applications. These applications highlight the opportunities arising from the rational design of small organic molecules with self-assembly properties for precision medicine.

Abstract:
Das grundlegende Verständnis der Adsorption, der Eigenschaften, und der Wechselwirkungen von komplexen organischen Molekülen auf Festkörperoberflächen ist für die Entwicklung neuer Anwendungen in der Nanotechnologie von entscheidender Bedeutung. Die in dieser Arbeit untersuchten funktionellen Bausteine gehören zu den Porphyrinen und Phthalocyaninen. Deren Adsorption, elektronische Struktur, und Reaktionen der Moleküle auf Edelmetalloberflächen wurden mit mehreren Methoden charakterisiert, insbesondere der Rastertunnelmikroskopie, Rastertunnelspektroskopie, Röntgen-Nahkanten-Absorptions-Spektroskopie und Photoelektronenspektroskopie, welche zudem durch theoretische Simulationen unter Verwendung der Dichtefunktionaltheorie ergänzt wurden. Tetra(p-hydroxyphenyl)porphyrin Moleküle ordnen sich durch Selbstorganisation zu verschiedenen, durch Wasserstoffbrückenbindungen stabilisierten Nanostrukturen an, welche in Abhängigkeit von dem Substratoberflächengitter untersucht wurden um das komplizierte Zusammenspiel von Molekül−Molekül und Molekül−Substrat-Wechselwirkungen bei der Selbstorganisation zu verstehen. Erhitzen der Adsorbatschichten dieses Moleküls führt zu einer schrittweisen Deprotonierung, und außerdem konnte auch ein Schalten der Leitfähigkeit einzelner Porphyrin-Moleküle durch lokale Deprotonierung mittels Spannungspulsen demonstriert werden. Eine Polymerisationsreaktion, welche auf der Ullmann-Reaktion basiert, aber direkt auf einer Oberfläche stattfindet, wurde für Kupfer-octabromotetraphenylporphyrin Moleküle, die auf Au(111) adsorbiert sind, gefunden. Nach einer thermischen Abspaltung der Bromatome von den Molekülen reagieren dabei die Radikalmoleküle bei hohen Temperaturen miteinander und bilden geordnete, kovalent gebundene Netzwerke aus. Die Bromabspaltung und die nachfolgenden Reaktionen und Veränderungen der elektronischen Struktur der Moleküle wurden ausführlich für die Substratoberflächen Au(111) sowie Ag(110) untersucht. Weiterhin, wird die Adsorption und Selbstorganisation von metall-freien Phthalocyanin-Molekülen auf einer Ag(110)-Oberfläche, und deren Selbstmetallierungsreaktion mit Silberatomen des Substrats umfassend und verständlich beschrieben. Zuletzt wurden organische Hybrid-Grenzflächen zwischen verschiedenen Metall-Phthalocyaninen untersucht, wobei ein Ladungstransfer zwischen Kobalt- und Platin-Phthalocyanin-Molekülen gefunden wurde. Dotierung gemischter Metall-Phthalocyanin-Filme durch Einlagerung von Kaliumatomen und deren selektive Adsorption im Molekülgitter führt zu einer deutlichen Veränderung der elektronischen Eigenschaften, aufgrund einer Ladungsübertragung an die Kobalt-Phthalocyanin Moleküle.

Abstract:
Loline alkaloids (LA) are secondary metabolites produced by Epichloandamp;euml; (anamorph, Neotyphodium) grass endophytes. They are toxic and deterrent to a broad range of herbivorous insects but not to livestock. This protective bioactivity has spurred considerable research into the LA biosynthetic pathway. LOL, the gene cluster containing nine genes, is required for LA biosynthesis. The regulation of LOL genes during LA production in culture and in symbio is of interest. In this study, coordinate regulation between LOL gene expression and LA production level was investigated in both MM culture and symbiota. Results showed that expression of LOL genes in N. uncinatum MM culture were tightly correlated with each other (p andamp;lt; 0.0005), and all presented a significant temporal quadratic pattern during LA production. Gene expression started before LA were detectable, and increased while LA accumulated. The highest gene expression level was reached before the highest amounts of LA were detected, and gene expression level declined to a very low level after amounts of LA plateaued. Observations suggested that the hierarchical clusters based on the correlation coefficient could help to predict the roles of LOL genes in the LA pathway. In symbiota, coordinate coregulation of LOL gene expression with LA was found in E. festucae-meadow fescue inflorescences and stromata, whereby lower LOL gene expression corresponded with the lower LA level in stromata. In N. uncinatum (or N. siegelii)-meadow fescue vegetative tissues, dramatically higher LA levels were found in younger leaf tissue than in older leaf tissue, yet no evidence was found to relate this difference to LOL gene expression differences. Instead, substrate availability may regulate the LA level. In particular, asparagine was more than 10-fold higher in young leaf tissue than in old tissue, although proline was significantly lower in young tissue. Therefore, different regulatory mechanisms underlie LOL gene expression and LA production in different circumstances. The GUS activity of Pro-lolC2-GUS and Pro-lolA2-GUS in Neotyphodium species was almost undetectable in culture, though the activity could be detected in symbiota. The mRNA of GUS did not exhibit the same pattern as lolC2 or lolA2 in culture during LA production time course. A Pro-lolC2-cre transgene was expressed in complex medium, in which lolC2 mRNA was not detectable. These results suggest that proper regulation of LOL genes in culture or symbiota is dependent on the LOL cluster.

Les fluorophores développés sont principalement des dérivés du bore-dipyrométhene (BODIPY), comportant des groupements réactifs (azoture, perfluorophényle), des chaines hydrophobes, ou sont intégrés à un récepteur de calcium biocompatible. Le développement d'architectures auto-assemblées multicompartimentées de type vésicules dans des polymersomes géant y est décrit. Ces architectures ont été utilisées pour la génération de lumière blanche dans un micro-domaine, et constitue un modèle pour l'étude de transfert d'ions calcium entre vésicules localisées dans des polymersomes individuels. Ce transfert entre nano-objets confinés à l'intérieur d'un polymersome géant représente un système prototype de communication cellulaire artificiel rudimentaire
The thesis focuses on the study and design of novel photoactive molecules and their application as labeling agents, fluorescent molecular Ca2+-sensors and photolabile Ca2+-decaging agents in aqueous media and organized supramolecular assemblies. The designed fluorophores are based on boron-dipyrromethene (BODIPY) bearing hydrophobic chains or a reactive group like an azide or a perfluorophenyl moiety. Biocompatible calcium receptors have been prepared harnessing the fluorescence properties of BODIPY, naphthalimide and furan fluorophores. The development of self-assembled multicompartmentalized architectures, namely fluorocarbon vesicles in giant polymersomes is reported and the system has been used to create white light emission in confined microdomains. The Ca2+-based ion transfer ion the confined polymer compartments between individual fluorinated vesicles has been studied.

Abstract:
Ce mémoire décrit la synthèse d’hôtes organiques et organométalliques contenant des motifs riches en électrons, particulièrement le tétrathiafulvalène (TTF), pour la complexation supramoléculaire de fullerènes C60 et C70. Le chapitre 1 est une revue de la littérature qui présente les notions de cavitant, de métallocavitant et des hôtes supramoléculaires. Le chapitre 2 présente les méthodes de caractérisation utilisées dans ce travail. Le chapitre 3 est consacré à une nouvelle méthode de synthèse de pinces moléculaires et des récepteurs tripodaux contenant l’unité riche en électrons (TTF). Les pinces triazoles ont été préparées par chimie « clic » entre l'azoture -TTF et des dérivés benzéniques disubstitués en position 1 et 3 par un acétylène. La réaction de l'azoture-TTF et des 1,3, 5-benzènes trisubstitués a donné des récepteurs tripodaux. L'affinité des hôtes avec les fullerènes C60 et C70 a été étudiée par la méthode optique spectroscopique UV-vis dans quatre solvants différents. La constante d’association la plus élevée a été calculée pour l’hôte 4 dans le chlorobenzène. Cependant, le récepteur tripodal n'a pas montré une affinité importante envers les fullerènes. Le chapitre 4 est consacré à la synthèse des nouveaux metallocavitands de zirconium TTF- Zr3 préparés par la méthode d’agrégation. Un seul hôte a été isolé et caractérisé par la méthode spectroscopique. Dans ce chapitre, nous présentons l'étude des interactions supramoléculaires avec les fullerènes en surveillant la réponse UV-vis à l’addition d’une quantité croissante de fullerènes à la solution contenant l’hôte. Le chapitre 5 décrit la synthèse de nouveaux metallocavitants de Zr3 à partir de la réaction de dichlorure de zirconocène sur l'acide carboxylique. Quatre metallocavitants de Zr3 ont été préparés. Les structures cristallographiques, les propriétés photophysiques et leurs utilisations potentielles en tant que matériaux émissifs bleus ont été présentées. Le chapitre 6 est séparé en trois sections. La première section décrit la synthèse et l’affinité de metallocavitant de tantale (V) avec les fullerènes. La deuxième section illustre la tentative de synthèse d’une librairie de Zr3 en utilisant la réaction de couplage croisée. Enfin, la dernière section présente la synthèse du nouveau metallocavitant de Ta3Carbox obtenu par la méthode d’agrégation à partir de la réaction de Cp*TaMe4 avec de l'acide 4 - iodobenzoïque. La structure est étudiée par rayons X.
This thesis described the synthesis of organic and organometallic hosts containing electron rich units in particularly tetrathiafulvalene (TFF) to bind fullerenes C60 and C70. Chapter two illustrates the different analysis techniques used in this thesis. Chapter three described new method for the synthesis of tweezers-like TTF and tripodal TTF molecules in addition to their binding affinity towards fullerenes C60 and C70. The tweezers-like TTF were prepared by click chemistry from azide-TTF and 1,3 substituted benzene. Similarly, the reaction of azide-TTF and 1,3, 5 substituted benzene yielded the tripodal-TTF receptor. The affinity toward fullerenes C60 and C70 were studied in four different solvents. The highest binding constant was calculated for host 4 in chlorobenzene toward fullerene C70. Moreover, solvent dependant behavior was observed with the studied host. However, the tripodal receptor did not showed significant affintity towards fullerenes. Chapter four described the synthesis of new TTF-Zr3 metallocavitand by coordination method; two hosts were isolated and characterized. In this chapter we present the binding study toward fullerenes by monitoring the UV-vis response to increasing amount of fullerenes added to the solution of the host. Chapter five described the synthesis of new Zr3 metallocavitand in one pot reaction from the reaction of zirconocene dichloride with carboxylic acid in aqueous media. Four Zr3 metallocavitand were prepared and the crystallography was presented in addition to the photophysical properties and their potential uses as blue emissive materials. The last chapter is separated into three sections. The first section described our early work on tantalum (V) metallocavitand in addition to their hosting capability toward fullerenes. The second section illustrate the tentative has been committed to the design and synthesis of Zr3 library using cross-coupling reaction in addition to the synthesis of extended Zr3-cinnamate metallocavitand. Lastly, the last section illustrates the synthesis of new Ta3-Carbox achieved by aggregation method from reaction of Cp*TaMe4 with 4-iodobenzoic acid. The single X-ray structure revealed a new structure with trimetallic core comparable to the core observed for tantalum metallocavitand.

Abstract:
Self-assembling molecules are central to a plethora of processes found in nature, biotechnology and even disease. The importance of the non-covalent interaction of monomers to the formation of fibrillar assemblies is evident in the repeated use of this mechanism throughout nature, from essential cellular processes such as the formation of the cytoskeleton to the production of silk. Further, it has been recognised in the last two decades that a self-assembly mechanism, that is the formation of amyloid, underpins the pathology of protein misfolding diseases; it is therefore essential to dissect these mechanisms. Despite recent technological and model system developments, self-assembling molecules remain challenging to investigate. Using combined structural and biophysical characterisations of penta- and hexa-peptide self-assembling model systems these investigations shed further light on the structure of amyloid-like fibrils. The elucidation of the structures of these fibrillar systems not only has implications for disease but also makes them well placed for consideration for biotechnological applications. In reflecting upon how cross-ß structural architectures can be organised in the fibrillar state, a molecular and supramolecular model of fibrils formed by a fragment of !-synuclein is reported. The fibrils are found to consist of a novel and elaborate cross-ß architecture that leads to a helical supramolecular assembly spanning length scales previously unobserved for such a system. Where self-assembly is a useful route to supramolecular structure formation, the use of low molecular weight gelator (LMWG) peptides to create fibrillar structures with defined material properties is also explored. The complex link between molecular structure, self-assembled architecture, fibril formation, fibril interaction and ultimately bulk material properties is described. It is found that the determinants of self-assembly are distinct from the determinants of gelation and so future LMWG design will have to consider both individually. This work presents methodological advances in the characterisation of self-assembled structures. The investigations presented here have relevance for disease related processes but also to the technological use of these systems as materials. Finally, this work emphasises the beauty of the extravagant, yet elegant connection between molecular interaction and supramolecular selfassembly.

Abstract:
The design and construction of artificial supramolecular architectures on surfaces is of great current interest and represents an important aspect of molecular self-assembly, because self-assembly offers highly ordered mesoscale structures with desired chemical functionalities and physical properties. The fabrication of polar molecular superstructures proves particularly challenging since polar molecular materials are essential to second-order nonlinear optical (NLO) technologies. Several approaches such as the Langmuir-Blodgett technique and liquid crystals have been reported to generate molecular-based materials with organized polar structures. However, the orientation in these materials is maintained by weak bonding or steric hindrance, which lose the polar alignment over time. Recent developments in self-assembly and host-guest chemistry offer a novel route to ordered materials through the design and synthesis of new molecular building blocks that can be organized into supramolecular assemblies. The synthetic approach here is to fix dipole orientation by structural interlocking of NLO chromophores into cone conformation, and then to utilize them to build polar self-assembled monolayers. In this report, we discuss the molecular design of calixarene-based, NLO molecular "pyramids", their monolayer self-assemblies on oxide surfaces, and their spectroscopic second order NLO properties.

Abstract:
Self-assembly of β-sheet forming peptides into filaments has drawn great interests in biomedical applications [1,2]; Hydrogels formed by filaments self-assembled from de novo designed peptides possess potential applications for cell culture scaffolds [3]. On the other hand, peptides derived from amyloidogenic proteins in neurodegenerative diseases such as Alzheimer’s and Parkinson’s also form similar β-sheet filaments in vitro. They share little sequence homology, yet filaments formed by these self-assembling peptides commonly have the cross-β structure, the key signature of the amyloid fibril. Detailed structural information of the self-assembled β-sheet filaments has been limited partly due to the difficulty in preparing ordered filament samples, and it has been only recently that solid-state nuclear magnetic resonance and x-ray techniques have revealed their molecular structure at the atomic level [4,5]. Although molecular structures of amyloid fibrils are becoming available, physical principles governing their self-assembly and the properties of the filaments are not well-understood, for which computational as well as theoretical approaches are desirable [6].

Abstract:
Hydrogel-based tissue engineering scaffolds can allow tissues to repair and regenerate by providing a 3D environment similar to soft tissue. Type I collagen has the ability to assemble into a fibrillar gel at physiological temperature and pH, while promoting cell adhesion and growth. Our lab has modified type I collagen by covalently adding methacrylate groups to lysine residues to create collagen methacrylamide (CMA). This biomaterial, like collagen, maintains the ability to self-assemble, and can then be photocrosslinked with long-wave UV light and a water-soluble photoinitiator, which allows extensive spatiotemporal control of mechanical and biochemical properties [1]. In characterizing CMA and developing it for other applications, we discovered an interesting property. Unlike type I collagen hydrogels, which maintain a stable fibrillar network during cooling and freezing, CMA will spontaneously disassemble at temperatures less than 10°C. In this paper, we discuss the temperature-dependent rheological properties of CMA as well as the nature of its molecular and supramolecular structure in comparison to collagen.

Abstract:
Polymeric microcapsules can be fabricated by using kernel process called “micro chemical plant system”. The size of microcapsules is more uniform than those made in the conventional pathways. Spherical microcapsules are fabricated through the innovative conjunction of the well-defined amphiphilic block copolymer and stable microfluidic procedure. Crossed microchannel chemical plant are fabricated by using double deep reactive ion etch (DRIE) on 400 μm-thick silicon wafer. The width and depth of this are 100 μm, respectively. PS-b-PMMA copolymer is synthesized by atomic transfer radical polymerization (ATRP) and molecular weight and poly dispersity index (PDI) is 9837 g/mol and 1.08, respectively. With the introduction of two immiscible fluids into the microchannel, droplet flows are visualized by using a high speed CCD camera. The microcapsule was formed due to supramolecular self-assembly of copolymer in the droplet. The characteristics of the produced microcapsules were measured by SEM. A new microfilter was also introduced to separate microcapsule from the suspension fluid.
