Abstract

A simple pyrene-based triazole receptor has been synthesised and shown to self-assemble in the presence of ZnCl2 in an exclusively 2[thin space (1/6-em)]:[thin space (1/6-em)]1 ratio, whereas a mixture of 2[thin space (1/6-em)]:[thin space (1/6-em)]1 and 1[thin space (1/6-em)]:[thin space (1/6-em)]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.
