Induction of supramolecular chirality in di-zinc(ii) bisporphyrin via tweezer formation: synthesis, structure and rationalization of chirality§

Abstract

Two new supramolecular complexes consisting of an achiral bisporphyrin host and a chiral diamine guest are reported. One shows a remarkably high amplitude bisignate CD signal while the other one shows a very low value. X-ray structure and other spectroscopic investigations of the tweezer complexes clearly rationalize the origin of the optical activity that has so far remained an unresolved issue.
