Abstract:
Herein, we present a facile synthesis of three azide-functionalized fluorophores and their covalent attachment as triazoles in Huisgen-type cycloadditions with model alkynes. Besides two ortho- and para-bromo-substituted benzaldehydes, the azide functionalization of a fluorene-based structure will be presented. The copper(I)-catalyzed azide–alkyne cycloaddition (CuAAC) of the so-synthesized azide-functionalized bromocarbaldehydes with terminal alkynes, exhibiting different degrees of steric demand, was performed in high efficiency. Finally, we investigated the photophysical properties of the azide-functionalized arenes and their covalently linked triazole derivatives to gain deeper insight towards the effect of these covalent linkers on the emission behavior.

Abstract:
Mesitylene was used as a core in seven new tritopic nitrogen containing linkers. Three of the linkers, each containing three nitrile groups, were obtained through Suzuki, Sonogashira and Heck-type coupling reactions. Next, these were converted to tetrazol-5-yl moieties by the cycloaddition of sodium azide to the nitrile functionalities. The last linker, containing three 1,2,3-triazol-4-yl moieties, was synthesized by the Huisgen cycloaddition of phenyl azide to the corresponding alkyne. The latter was obtained via a Corey–Fuchs reaction sequence from the previously reported formyl derivative. As the proof of concept for their potential in MOF design, one of the nitriles was used to build an Ag-based network.

Abstract:
Many clinically relevant therapeutic agents are formed from the conjugation of small molecules to biomolecules through conjugating linkers. In this study, two novel conjugating linkers were prepared, comprising a central coumarin core, functionalized with a dimaleimide moiety at one end and a terminal alkyne at the other. In our first design, we developed a protein labelling method that site-specifically introduces an alkyne functional group to a dicysteine target peptide tag that was genetically fused to a protein of interest. This method allows for the subsequent attachment of azide-functionalized cargo in the facile synthesis of novel protein-cargo conjugates. However, the fluorogenic aspect of the reaction between the linker and the target peptide was less than we desired. To address this shortcoming, a second linker reagent was prepared. This new design also allowed for the site-specific introduction of an alkyne functional group onto the target peptide, but in a highly fluorogenic and rapid manner. The site-specific addition of an alkyne group to a protein of interest was thus monitored in situ by fluorescence increase, prior to the attachment of azide-functionalized cargo. Finally, we also demonstrated that the cargo can also be attached first, in an azide/alkyne cycloaddition reaction, prior to fluorogenic conjugation with the target peptide-fused protein.

In this study, the synthesis of a telechelic linker bearing both azide and thiol functional groups was described. The reaction conditions were investigated to optimize the reaction yield. The product was analyzed using thin layer chromatography (TLC) and proton nuclear magnetic resonance (1H NMR). The employment of the obtained azide–thiol linker in heterogeneous polymer “click” functionalization was demonstrated for the first time, which was monitored by an online FT–IR method. The obtained telechelic azide–thiol linker is envisioned to be useful chemical tools to link macromolecular chains via orthogonal click reactions.

SYNOPSIS OF THIS THESIS The aim of this thesis is to more fully understand and explain the binding mechanism of organic molecules to the Au(111) surface and to explore the conduction of such molecules. It consists of five discreet chapters connected to each other by the central theme of “The Single Molecule Device: Conductance and Binding”. There is a deliberate concentration on azine linkers, in particular those with a 1,10-phenanthroline-type bidentate configuration at each end. This linker unit is called a “molecular alligator clip” and is investigated as an alternative to the thiol linker unit more commonly used. Chapter 1 places the work in the broad context of Molecular Electronics and establishes the need for this research. In Chapter 2 the multiple break-junction technique (using a Scanning Tunnelling Microscope or similar device) was used to investigate the conductance of various molecules with azine linkers. A major finding of those experiments is that solvent interactions are a key factor in the conductance signal of particular molecules. Some solvents interfere with the molecule’s interaction with and attachment to the gold electrodes. One indicator of the degree of this interference is the extent of the enhancement or otherwise of the gold quantized conduction peak at 1.0 G0. Below 1.0 G0 a broad range for which the molecule enhances conduction indicates that solvent interactions contribute to a variety of structures which could bridge the electrodes, each with their own specific conductance value. The use of histograms with a Log10 scale for conductance proved useful for observing broad range features. vi Another factor which affects the conductance signal is the geometric alignment of the molecule (or the molecule-solvent structure) to the gold electrode, and the molecular alignment is explored in Chapters 3 for 1,10-phenanthroline (PHEN) and Chapter 4 for thiols. In Chapter 3 STM images, electrochemistry, and Density Functional Theory (DFT) are used to determine 1,10-phenanthroline (PHEN) structures on the Au(111) surface. It is established that PHEN binds in two modes, a physisorbed state and a chemisorbed state. The chemisorbed state is more stable and involves the extraction of gold from the bulk to form adatom-PHEN entities which are highly mobile on the gold surface. Surface pitting is viewed as evidential of the formation of the adatom-molecule entities. DFT calculations in this chapter were performed by Ante Bilic and Jeffery Reimers. The conclusions to Chapter 3 implicate the adatom as a binding mode of thiols to gold and this is explored in Chapter 4 by a timely review of nascent research in the field. The adatom motif is identified as the major binding structure for thiol terminated molecules to gold, using the explanation of surface pitting in Chapter 3 as major evidence and substantiated by emergent literature, both experimental and theoretical. Furthermore, the effect of this binding mode on conductance is explored and structures relevant to the break-junction experiment of Chapter 2 are identified and their conductance values compared. Finally, as a result of researching extensive reports of molecular conductance values, and having attempted the same, a simple method for predicting the conductance of single molecules is presented based upon the tunneling conductance formula.

Abstract:
Two-photon absorption and two-photon excitation fluorescence of salicylaldehyde azine crystals were investigated. It was observed an intense visible fiuorescence when this material was excited with a laser tuned at the near infrared region. Varying the laser intensity we identified this phenomenon as a simultaneous two-photon laser absorption process. Using open aperture Z-scan measurements we characterized this two-photon absorption phenomenon and measured the value of the two-photon absorption crosssection of this molecule to be equal to 87 GM. Our results indicate that this is a promising organic material aiming nonlinear photonics applications.

The synthesis of cyclic amphiphilic graft copolymers with a hydrophobic polycarbonate backbone and hydrophilic poly(N-acryloylmorpholine) (PNAM) side arms via a combination of ring-opening polymerization (ROP), cyclization via copper-catalyzed azide–alkyne cycloaddition (CuAAC), and reversible addition–fragmentation chain transfer (RAFT) polymerization is reported. The ability of these cyclic graft copolymers to form unimolecular micelles in water is explored using a combination of light scattering, small-angle X-ray scattering (SAXS), and cryogenic transmission electron microscopy (cryoTEM) analyses, where particle size was found to increase with increasing PNAM arm length. Further analysis revealed differences in the solution conformations, loading capabilities, and morphologies of the cyclic graft copolymers in comparison to equivalent linear graft copolymer unimolecular micelle analogues. Furthermore, the cyclic and linear graft copolymers were found to exhibit significantly different cloud point temperatures. This study highlights how subtle changes in polymer architecture (linear graft copolymer versus cyclic graft copolymer) can dramatically influence a polymer’s nanostructure and its properties.

Abstract:
l volume propone una rinnovata lettura della libertà di manifestazione del pensiero, classico tema della riflessione costituzionalistica, attraverso un'analisi casistica articolata su due livelli. Il lavoro ripercorre sia la giurisprudenza costituzionale sui limiti alla libertà di espressione e sui mezzi di diffusione del pensiero, sia gli orientamenti dei giudici ordinari e amministrativi su alcuni casi emblematici riguardanti, ad esempio, le opinioni razziste e "negazioniste"; il diritto di cronaca, di critica politica, di satira; la disciplina del mercato radiotelevisivo, della par condicio e della stampa on-line. La libertà di espressione è così descritta "in azione", a partire dall'opera delle Corti, che assurgono al rango, tanto promettente quanto impegnativo, di "custodi" del discorso pubblico, cioè di uno spazio di comunicazione che contribuisce a fondare l'autonomia politica di individui e soggetti privati.

Abstract:
A rapid, facile, and modular surface modification scheme for the covalent attachment of pre-formed polymer moieties to self-assembled monolayers via ‘click’ chemistry within glass microfluidic channels (3 cm long, 110 μm wide and 15 μm deep) is described. The effect that different moieties have on the electroosmotic flow (EOF) within the microchannels is evaluated. The application of linear polymers such as poly(ethylene glycol) (PEG) generates hydrophilic surfaces that reduce the analyte-wall interactions, thereby increasing separation efficiency and improving resolution, especially in bio-separations. Dendritic polymers such as poly(amido amine) (PAMAM) on channel walls can provide high-surface area structures with tunable surface charge depending on the generation of the dendrimer coating. Modified surfaces are characterized by X-ray photoelectron spectroscopy (XPS), Fourier Transform Infrared-Attenuated Total Reflection spectroscopy (FTIR-ATR), and contact angle measurements. EOF measurements in modified and unmodified channels provide information about wall-analyte interactions. A PAMAM dendrimer coated channel presents an amine terminated surface with a positive charge in contrast to a negatively charged bare-glass surface. Use of surface coatings can lead to an increase of the EOF by 15% as is the case for an azide terminated surface or reverse the direction of EOF as is the case for the PAMAM coatings by changing the surface charge polarity.

Abstract:
La promozione della qualità della vita urbana passa necessariamente attraverso la costruzione di una città inclusiva, una città effettivamente "usabile" da tutti i suoi abitanti. Anche e soprattutto da chi, a causa di una qualche condizione (permanente o temporanea), si discosta dall'immagine dell'abitante-tipo adulto, maschio, sano, istruito, ricco e automunito e non é quindi "capace" (o non lo è pienamente) di accedere ai luoghi, ai servizi, alle opportunità e alle informazioni della città che sono progettate, organizzate e governate precisamente in funzione delle esigenze e dei desideri di questo abitante-tipo. Rilevanti sono in tal senso i progetti e le politiche che si concentrano soprattutto sulle periferie con l'intento di promuovere la qualità della vita urbana quotidiana degli abitanti . Accanto ai grandi (e costosi) interventi di riqualificazione, particolarmente utili sono le trasformazioni a scala di quartiere, le "micro" trasformazioni, perché sono in grado di migliorare concretamente l'usabilità di quella che può essere definita "città quotidiana e di prossimità", la città, cioè, che gli abitanti conoscono, "usano" (o "userebbero" se fosse effettivamente accessibile e usabile) e di cui possono prendersi cura. L'articolo cerca di mostrare perché è efficace e pertinente un approccio legato ad una dimensione "micro" degli interventi, anche attraverso il racconto di alcune esperienze sul campo condotte da Tamalacà, un gruppo di ricerca e azione del Dipartimento di Architettura Design e Urbanistica (DADU) dell'Università di Sassari. Upgrading the quality of urban life necessarily goes hand in hand with building up an inclusive city, a city actually “usable” by all its inhabitants. The kind of project that is important from this point of view will focus on the most marginal areas of the city. Alongside the large, costly urban redevelopment interventions, transformations on a neighbourhood scale and "micro" dimension are particularly useful. This article attempts to show why an approach involving intervention linked with a “micro” dimension is effective and pertinent, and also describes a significant experiment carried out by the action research group TaMaLaCà of the Department of Architecture Design and Planning - Architecture at Alghero (University of Sassari) in the town of Sassari.
