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).
