Abstract:

Two examples of artificial supramolecular host-guest systems derived from resorc[4]arenes (calix[n]arenes based on resorcinol) and ammonium ions as guests have been studied by atomic force microscopy (AFM). For the first time, real single-molecule events have been determined for this type of supramolecular complexes and off-rates as well as molecular parameters of single-molecule aggregates such as the depths of the binding pocket (molecular length parameter) could be measured by applying the methods of dynamic force spectroscopy. In addition, this technique was also applied to differentiate b

Abstract:

A supramolecular gel is a fascinating combination of flexibility and orderliness. While the supramolecular nature of crosslinking contributes towards the adaptivity and the reversibility of the system, orderliness at the molecular level amplifies the functional output and induces extraordinary selectivity into the system. Therefore, use of supramolecular gels as the soft template is an emerging area of research, which includes but not limited to catalysis of a chemical or a photochemical process, transcription of gel property to a substrate, or even controlling the nucleation of drug molecules

Abstract:

Supramolecular chirogenesis represents an effective way to induce chirality at the supramolecular level. For the previous host–guest chirogenic systems, metal–ligand coordination, hydrogen bonding, π–π stacking and hydrophobic interactions have been mainly employed as the non-covalent driving forces. In this study, Pt(II)···Pt(II) metal–metal interactions have been engineered to induce supramolecular chirogenesis, by forming non-covalent clipping structures between chiral platinum receptors and achiral platinum guests together. This results in the emergence of Cotton effects in the metal–metal

Abstract:

Guanosine is an important building block for supramolecular gels owing to the unique self-assembly property that results from the unique hydrogen bond acceptors and donor groups. Guanosine-derived supramolecular hydrogels have promise in the fields of drug delivery, targeted release, tissue engineering applications,etc.However, the property of poor longevity and the need for excess cations hinder the widespread applications of guanosine hydrogels. Although guanosine-derived supramolecular hydrogels have been reviewed previously by Dash et al., the structural framework of this review is differe

Abstract:

Supramolecular gels are complex materials which have an expanding scope of industrial and biomedical applications, due to their unique viscoelastic properties, high biocompatibility and possibility of functionalisation. The hierarchical structure of molecular materials combines domains with drastically different degrees of ordering and molecular mobility. This makes their full characterisation a significant methodological and experimental challenge. The focus of this work was therefore the understanding of a variety of supramolecular semicrystalline gels in which very rigid solid components co

Abstract:

Beyond their application in switchable optical materials, photochromic molecules are also solid building blocks to make nanoscopic objects light-responsive, in order to control molecular motions, convert and store light into chemical energy, or drive chemical reactions. An outstanding quality, in these regards, is the possibility of operating a minor variation on the photochrome structure, such as via covalent or supramolecular strategies, that can ultimately result in a large tuning of the photoresponsivity, both at the molecular and material level. The PhD manuscript here highlighted, titled “Novel Photo- and Electro-responsive Supramolecular Systems and Molecular Machines” and awarded the 2020 European Photochemistry Association PhD Prize, covered several studies on how azobenzene- and terarylene-based photochromes can be employed as photoresponsive components of smart materials and how minor adjustments on their molecular structure can generate drastic changes in their performance, in a sort of butterfly effect fashion.

Abstract:

Multi-drug therapy involves the simultaneous or sequential administration of two or more drugs with similar or different mechanisms of action and is efficient in combating various ailments such as cancer, diabetes, and rheumatoid arthritis. It has emerged advantageous due to larger therapeutic benefits, an increase in patient compliance, lower administrative costs, and reduced number of prescriptions. In the recent past, the clinical success of the Novartis product Entresto (sacubitril, disodium valsartan and water) and Esteve product E-58425 (tramadol and celecoxib) has boosted the development of multi-drug . The present article is hence designed to provide an overview of different multicomponent addicts which provide option of combining the drugs at a supramolecular level (nano-sized level). Key features of multi-drug cocrystal, co-amorphous system and eutectics are described with major emphasis on screening tools, preparation methods, characterization techniques, biopharmaceutical aspects and scale up.

Full text

Abstract:

Flexible metal–organic frameworks (MOFs) form an attractive class of solid-state materials that exhibit structural softness and a discernible response to external stimulus, physical or chemical. These features make them suitable for several applications for energy, environment and biomedicine, with the ability to tune their characteristics at the molecular level. This chapter provides a detailed analysis of their synthesis and structural properties, with the aim to derive design principles. The flexibility is stated at two levels: one part with the focus on the building blocks of such systems, and the other considering the topological viewpoint in their supramolecular assemblies. The role of metals, ligands and guest molecules in influencing their dynamic nature is discussed with several examples from a range of MOFs. The chapter closes with a perspective on the factors that can enable complete understanding of flexibility in MOFs and thereby lead to a greater understanding in terms of designing such materials.

Abstract:

Azobenzene is a well-known dye that undergoes fast trans-cis photoisomerization and has been widely studied and used in the development of organic functional materials. Due to its selective isomeric distribution in the excited state, azobenzene has been used as a photoswitch in the storage of information on a molecular level, photo-controllable catalysis, solar light harvesting, photo-pharmacology, optical-to-mechanical energy conversion, molecular electronic, and photonic devices. Furthermore, the characteristic and distinguishable photoelectronic properties of trans and cis azobenzene have been recently used in the sensing properties of different ions and the recognition of molecules. Here, we are going to review the recent literature where different intermolecular forces show the supramolecular properties under the stimuli of photo-light.

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
