Abstract

A novel ethynylpyridine containing E-Bodipy, 2 was synthesized from a Bodipy precursor 1 and its chemosensing properties towards various transition metal ions including Fe³⁺, Co²⁺, Cu²⁺, Zn²⁺ and Hg²⁺ were investigated. A large fluorescence enhancement of 2 was observed upon treatment with Zn²⁺ whereas addition of Fe³⁺, Co²⁺, or Cu²⁺ caused fluorescence quenching of 2, which suggests its potential application as a turn-on fluorescent chemosensor for Zn²⁺. The photophysical behaviors of 1 and 2 were characterized by spectroscopic and electrochemical methods. In addition, the structure and electronic properties of 1, 2 and its metal complex with Zn²⁺ were investigated by density functional theory (DFT) calculations.
