A series of functionalized coumarino[4,3-d]pyrazolo[3,4-b]pyridine derivatives 3a~3h were synthesized by the addition and cyclization of 3-acetoacetylcoumarin with 5-aminopyrazole catalyzed by CuSO4. Some of the synthesized compounds had high fluorescence quantum yields. The properties of the compounds with cations such as Ag+, Cr3+, Co2+, Cu2+, Pb2+, Sn4+, Fe3+ and Zn2+ were examined by fluorescence spectroscopy. The results showed that compounds 3a and 3b have selective recognition for Zn2+.

Key words: coumarino[4,3-d]pyrazolo[3,4-b]pyridine derivative, synthesis, fluorescence property, Zn2+, selective recognition
