Abstract

A simple pyrene-based triazole receptor has been synthesised and shown to self-assemble in the presence of ZnCl2 in an exclusively 2:1 ratio, whereas a mixture of 2:1 and 1:1 ratios are observed for other Zn2+ salts. The pyrene units are syn in orientation, this is supported by a strong excimer signal observed at 410 nm in the presence of ZnCl2 in acetonitrile. DFT calculations and 2D NMR support the proposed structure.
