Abstract

A new type of benzimidazole-based imine-linked fluorescence chemosensor for Zn^{2 +} was synthesized. Coordination of Zn^{2 +} with the receptor led to enhanced fluorescence while other metals quenched the receptor fluorescence. The resulting complex had a supramolecular assembly with a 1:1 host-guest ratio with variable size. The (1.Zn^{2 +})_n assembly showed high selectivity towards the complexation of L-cysteine even in the presence of other potentially competitive biologically important anionic species.
