Chem. Commun., 2015, 51,895-898
DOI: 10.1039/C4CC07955H, CommunicationSk Asif Ikbal, Sanfaori Brahma, Sankar Prasad Rath
A clear structural rationalization of the origin of chirality transfer from an optically active diamine guest to an achiral Zn(II) bisporphyrin host in a 1 : 1 and 2 : 3 host-guest supramolecular complex has been demonstrated for the first time. During the process, chirality inversion along with amplification was observed.
