The Donor-Acceptor Approach to Molecular Interactions

DOWNLOAD EBOOKRecent developments in various areas of chemistry have been decisively influenced by the principles of structure and mechanism and by the ideas of coordination chemistry, in particular by the donor-acceptor approach, A unified view of almost all kinds of molecular forces is provided by quantum mechanics, and for practical purposes have been classified according to model assumptions, namely, dispersion, polarization, electrostatic, and short-range forces. The latter are divided into two- and three-center covalent chemical bonds, metallic bonds, and exchange-repulsion forces. This approach allows statements of principle and systematic analysis. However, quantitative predictions on concrete large systems are virtually impossible, and there are no general rules that account for structural and chemical changes due to intermolecular interactions. Chemists are therefore left with qualitative descriptions in which the changes in electron densities are considered. Such models as the MO theory or the resonance concept unrealistically assume that the nuclei remain in fixed positions. Further difficulties are encountered in the attempted description on the "nature" of the chemical bond, e.g., the forces involved. In order to avoid these difficulties an extension of the donor-acceptor concept, characterized by the comparison between equilibrium structures in different molecular environments, will be presented in this book. In this way, changes in the positions of the nuclei can be taken into account and the question of the nature of the molecular forces is no longer important.

DOWNLOAD EBOOKThis book documents the proceedings of the Second International Symposium on Acid-Base Interactions: Relevance to Adhesion Science and Technology held in Newark, New Jersey, October 19--21, 1998. Since the first symposium on this topic was held on the occasion of the 75th birthday of Professor Frederick M. Fowkes in 1990, it was deemed opportune and necessary to hold the second symposium on this topic. This symposium was organized with the following objectives in mind: (i) to consolidate the R&D activity carried out since the first symposium, (ii) to provide a forum for discussion of latest research results, (iii) to provide an opportunity for cross-pollination of ideas, (iv) to identify topics where there was discordance of opinion or discrepancy, and (v) to highlight areas which needed intensified R&D activities. The final technical program contained a total of 36 papers by researchers and technologists from academia, industry and other organizations. This book contains a total of 32 papers, which were rigorously peer reviewed and suitably revised before inclusion in this book. The book is divided into three parts as follows: Part 1: Fundamental Aspects of Acid-Base Interactions; Part 2: Characterization of the Acid-Base Properties of Materials; and Part 3: Applications of Acid-Base Interactions. The topics covered include: Surface free energy acid-base theory applied to solid surfaces; Good, van Oss and Chaudhury theory; contact angle measurements and interpretation; acid-base theory of contact angles; acid-base strength of solid surfaces; acid-base interactions at solid surfaces; acid-base interactions at the molecular level; characterization of acid-base properties of a host of materials (polymers, wood, glass, ceramics, silica particles, textile fibers, rocks) by XPS, inverse gas chromatography, immersion calorimetry, contact angle titration, and thin layer wicking; and relevance of acid-base interactions to bioadhesion, microbial adhesion, polymer adhesion, and adhesion in reinforced polymer composites.

DOWNLOAD EBOOKCyclophanes are bridged aromatic compounds and represent the central class of synthetic receptors in molecular recognition. All types of substrates, from inorganic and organic cations and anions, to neutral molecules have been complexed by tailor-made cyclophanes. This monograph focuses on the principles of supramolecular complexation and catalysis. It provides a state-of-the-art review of the intermolecular forces that hold together the supramolecular complexes of cyclophanes with neutral and charged organic molecules in the liquid phase. Cyclophanes also demonstrates the characteristics and advantages of bridged aromatic compounds as receptors. The book has great clarity, is very readable and will be extremely useful in both teaching and research.
