Abstract

A new bispyrenyl azadiene derivative has been synthesized and examined for its cation recognition abilities toward different cations. The ligand shows strong affinity for Hg2+ ions over other cations such as Cu2+, Pb2+, Zn2+, Ni2+, Cd2+, Ag+, K+, Na+ and Li+. An “Off-On” type of fluorescent behaviour was observed with simultaneous presence of Cu2+ and Hg2+ ions. An ion selective electrode (ISE) is also formed which showed excellent selectivity to Hg2+ over all the other cations tested. The lower limit of detection is 7.08 × 10−6 M.
