Abstract
A simple fluorescent chemosensor 2-(furan-2-yl)-4,5-diphenyl-1H-imidazole (P1) based on an imidazole furan conjugate has been designed, synthesized and characterized. Fluorimetric studies on chemosensor P1 showed excellent selectivity toward Cu2+ ions over other metal ions in aqueous media through a “turn on−off” process. A possible reverse photoinduced electron transfer mechanism is proposed. The viability of P1 to Cu2+ has been demonstrated by live cell imaging.
