Abstract

A new anthracene-appended benzimidazolium-based receptor 1 has been designed and synthesised. The receptor shows selective recognition of iodide in the excited state by exhibiting quenching of emission of anthracene. In the ground state, receptor 1 shows different selectivity and prefers to bind bromide with higher binding constant value as established from NMR titration experiment. Other anions in the study indicated weak or no ...
