Supramolecular chemistry of thiazole based urea thiourea and imine amine derivatives polymorphism molecular ion recognition

Abstract

Self assembly guided by noncovalent interactions is one of the fundamental features associated with biological systems Inspired by this biological phenomenon self assembly has become a key step for miniaturization of functional devices and the development of future nanotechnology Based on free rotation of C N bond over intramolecularly hydrogen bonded six membered synthon of a phenyl thiourea tethered thiazole derivative three polymorphs were isolated Each polymorph was obtained by crystal
