Available in PDF, EPUB and Kindle. Book excerpt: Chirality, familiar to all chemists, is usually applied to molecules or assemblies of molecules and plays an important role in both animate and inanimate systems. It is commonly the case that chirality of a system arises from a chiral building block yet chiral systems can also emerge from achiral units. The objective of this research was to investigate the origin and recognition of chirality at the nanoscale level. To do this, self assembled monolayers made of chirally and achirally tailed molecules were used because such structures are known to form uniform surfaces, which can act as either a source of nucleation or the probing surfaces in chiral recognition. The strategy adopted in the first part of this study was to use chirally modified self assembled monolayers as a source of nucleation for crystallization of achiral compounds that can form either left or right tended forms in chiral crystallization. Such compounds, widely reviewed by Matsura, form chiral crystals even though their building blocks lack a chiral centre. This study presents experiments of induction of chirality in sodium chlorate, hippuric acid and 2,6-ditertbutyl-4-methylphenol crystals. Chiral crystallization of chosen compounds was conducted on D and L cysteine surfaces assembled on gold. The chirality of crystals grown on these surfaces was determined using polarised light microscopy, circular dichroism spectroscopy and NSOM. The small enantiomeric excess achieved in experiments was explained by the limits of chirality determination methods. It was found that crystals formed in enantiomeric excess were of opposite chirality to the SAM they were grown on. This confirms previous results presented by Mastai on crystallization of histidine on cysteine surfaces. The second part of this study presents studies of chiral recognition use of AFM technique-Force Distance Spectroscopy. Chirally and achirally modified SAMs were formed via the Cu-AAC reaction commonly called 'click Chemistry'. This project investigated how the surface preparation influences chiral recognition and if the presence of the second chiral centre affects probing ability. For surface preparation, three types of linkers were used. To functionalize them two complementary compounds equipped with AlaAlaDL and AlaAlaLL dipeptide tail were used. Additional studies were carried out with hippuric acid and glutamic acid-modified SAMs. These studies showed that the way the surface is prepared plays an important role in chiral recognition. In the final recognition experiments it was found that use of molecules possessing either peptide groups or amino acid groups generates additional forces between interacting surfaces, which can be equilibrated by conducting measurements in pH close to their isoelectric point. An influence of the second chiral centre was found for the loosely packed surfaces where the molecules can freely coil.
Download or read book Chirality in Supramolecular Assemblies written by F. Richard Keene and published by John Wiley & Sons. This book was released on 2017-01-03 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supramolecular chemistry deals with the organisation of molecules into defined assemblies using non-covalent interactions, including weaker and reversible interactions such as hydrogen bonds, and metal-ligand interactions. The aspect of stereochemistry within such chemical architectures, and in particular chirality, is of special interest as it impacts on considerations of molecular recognition, the development of functional materials, the vexed question of homochirality, nanoscale effects of interactions at interfaces, biocatalysis and enzymatic catalysis, and applications in organic synthesis. Chirality in Supramolecular Assemblies addresses many of these aspects, presenting a broad overview of this important and rapidly developing interdisciplinary field. Topics covered include: Origins of molecular and topological chirality Homochirogenesis Chirality in crystallinity Host-guest behavior Chiral influences in functional materials Chirality in network solids and coordination solids Aspects of chirality at interfaces Chirality in organic assemblies Chirality related to biocatalysis and enzymes in organic synthesis. This book is a valuable reference for researchers in the molecular sciences, materials science and biological science working with chiral supramolecular systems. It provides summaries and special insights by acknowledged international experts in the various fields.

Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology has received tremendous interest over the last decade, not only from the scientific community but also from a business perspective and from the general public. Although nanotechnology is still at the largely unexplored frontier of science, it has the potential for extremely exciting technological innovations that will have an enormous impact on areas as diverse as information technology, medicine, energy supply and probably many others. The miniturization of devices and structures will impact the speed of devices and information storage capacity. More importantly, though, nanotechnology should lead to completely new functional devices as nanostructures have fundamentally different physical properties that are governed by quantum effects. When nanometer sized features are fabricated in materials that are currently used in electronic, magnetic, and optical applications, quantum behavior will lead to a set of unprecedented properties. The interactions of nanostructures with biological materials are largely unexplored. Future work in this direction should yield enabling technologies that allows the study and direct manipulation of biological processes at the (sub) cellular level.
