摘要：

A new pyrazoline derivate was designed and synthesized. The structure of the pyrazoline was confirmed by single crystal X-ray diffraction and its photophysical properties were studied by absorption and fluorescence spectra. This compound can be used to determine Cu2+ ion with high selectivity and sensitivity among a series of cations in aqueous tetrahydrofuran. This sensor forms a 1:1 complex with Cu2+ and displays fluorescent quenching. (C) 2012 Elsevier Ltd. All rights reserved.
