Fund Project: This research was supported by the NNSFC (Nos.20332020,20472079).

A novel fluorescence enhancement Cu²⁺chemosensor derived from coumarin was prepared. Emission study found that it exhibits evident Cu²⁺-amplified fluorescence prior to Co²⁺, Pb²⁺, Mg²⁺, Mn²⁺, Ni²⁺, Zn²⁺, Fe³⁺, Ag⁺ and Cd²⁺, and the largest emission enhancement factor is about 9 at a ratio of 2:1 (chemosensor 1/Cu²⁺)
