About this collection
The Mechanics of Supramolecular chemistry refers to the underlying “physical organic chemistry” of the field. This collection of works, Guest Edited by Professor Tony James, Professor Jonathan Sessler and Professor Bruce Gibb, was conceived to celebrate the 60th Birthday of Eric V Anslyn who has been an inspiration to countless minds working on solving the fundamental science behind supramolecular chemistry.
”My childhood was filled with repairing and constructing mechanical entities, such as internal combustion motors, where many components work together to achieve a function. Analogously, the field of supramolecular chemistry creates systems of high complexity that achieve functions or perform tasks. Therefore, in retrospect a career in supramolecular chemistry appears to be simply an extension of childhood hobbies”
