Abstract

A pyrene derivative has been synthesized as a visible light excitable fluorescent chemodosimeter which exhibits “on–off” and “green–red” fluorescence behavior for Ni²⁺ and Pb²⁺ with different reaction speed, respectively, and its sensing ability toward metal cations and counter ions was investigated in detail. The high selectivity of the ‘in situ’ prepared Ni²⁺ and Pb²⁺ complexes toward EDA and the reaction speed difference provide two new effective methods for distinguishing between Ni²⁺ and Pb²⁺.
