This conference is dedicated to a very fundamental concept in chemistry and material science - chemical bonding. For centuries, qualitative ideas of chemical bonding (such as Lewis electron pair, covalency, aromaticity, conjugation and hyperconjugation) helped scientists in the rationalization and prediction of molecular structures and properties. To date, the theory of chemical bonding keeps undergoing its rapid development, with new and unexpected aspects of chemical bonding continuously being discovered, and new functional materials being prepared along the way. This annual meeting will bring in theorists and experimentalists who probe and reveal new aspects of chemical bonding in matter and bond manipulation, and who use their research for the rational design of materials and property analysis.
