Abstract

A di-triazole based peptide has been synthesised by copper catalyzed Huisgen cycloaddition. Fluorescence intensity is enhanced selectively in the presence of Zn2+, which is ascribed to reversal of photoelectron transfer. Compound 7 was found to self-assemble in the presence of Zn(ClO4)2 in an exclusive 2 : 1 ratio, which is supported by 1H NMR titration and mass spectral data. The fluorescence intensity of 7 shows a subsequent ON–OFF phenomenon upon repetitive and alternate addition of Zn(ClO4)2 and HClO4.
