The crystal structure of compound 1 is stabilized by C–H…O, N–H…N, N–H…O, O–H…N and C–H…N hydrogen bonds. The spectroscopic studies of the title compound toward various metal ions were also investigated in 25%(V/V) ethanol aqueous solution, and the result showed that it can selectively recognize Cu^2+ with fluorescence quenching.展开更多
