Synthesis of Prodigious Supramolecules and Their Characterization Bharat Makwana

This book deals with the rapid, eco-friendly and convenient method of synthesis of parent calix[4]resorcinarene (basic calix platforms) using microwave irradiation technique. The basic calix platform has been further functionalised as its ester and hydrazide derivatives. In effect, two calix[4]resorcinarene hydrazides i.e. one having twelve and other having four hydrazide groups on the periphery of basic calix platforms have been synthesized. The structures of all basic calix platforms and their derivatives have been confirmed on the basis of various physico-chemical techniques such as elemental analysis, FT-IR, 1H NMR, ESI-MS and 13C NMR spectroscopy. Single crystal structure of basic calix platforms i.e. 5,11,17,23-tetra methyl calix[4]resorcinarene and octamethoxy calix[4]resorcinarene has also been reported. In recent years, microwave technology has created an undeniable place for itself in chemical laboratory practice as a very effective and non-polluting method for activating reactions.
