The optical properties of the compound were investigated in a methanol： HEPES solution. The compound displayed selectivity for Cu2＋, as evidenced by a colorless to yellow color change, which was characterized using UV-vis spectroscopy. The fluorescence of the compound can be quenched only by Cu2＋, accompanying by a color change from blue to colorless. Furthermore, it can be used in bioimaging.展开更多
