5.1 Introduction

Sommario/riassunto

In the past few years, supramolecular chemistry has led to new approaches in homogeneous catalysis. While host-guest chemistry had already found applications in catalysis as a result of the pioneering work carried out by Professor Ronald Breslow and Nobel prizewinner Professor Jean-Marie Lehn that began some 40 years ago, the construction of catalysts by supramolecular forces has only recently become a powerful tool. This development paves the way for large numbers of new potential catalysts that can be varied in an expedient way by changing the constituting building blocks.Written by some
