Application of Imidazole Derivative for Fluorescent Detection and Determination of Cu(II) in Aqueous and Biological Media

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 Cu 2+ ions over other metal ions in aqueous media throug...

Description
Summary: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 Cu 2+ 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 Cu 2+ has been demonstrated by live cell imaging.
