Abstract

A novel tren-based tripodal chemosentor 1 bearing a rhodamine and two tosyl groups was synthasized and its sensing behavior toward metal ions was investigated by UV/vis and fluorescence spectroscopies. Addition of a Hg 2+ ion to a CH3CN solution of 1 gave a visual color change as well as significantly enhanced fluorescence, while other ions including Pb2+, Zn2+, Cu2+, Ca2+, Ba 2+, Cd2+, Co2+, Mg2+, Ag +, Cs+, Li+, and Na+ induced no or much smaller color/spectral changes, which constituted a Hg2+- selective fluorescent chemosensor (OFF-ON).
