Abstract

A new phosphorescent chemosensor for Hg²⁺ and acetonitrile (MeCN) based on iridium(iii) complex Ir(dpp)₂(dtc) (Ir1, dppH = 4,6-diphenylpyrimidine, dtcH = diethyl dithiocarbamic acid) was realized. Upon addition of a tetrahydrofuran (THF) solution of Hg²⁺, the dichloromethane (DCM) solution of Ir1 gave a visual color change and significant fluorescent quenching. When MeCN was added, a new fluorescent emission emerged, which constituted a selective MeCN phosphorescent chemosensor. Complex Ir1 has been developed as an AND logic gate with Hg²⁺ and MeCN as inputs.
