摘要：

Herein we report the selective detection of Cu2+ and SO3 (2-) by phenanthraquinone thiosemicarbazone (PQTSC) chemosensor. The chemosensor is efficient in detecting Cu2+ over other metal ions, while the PQTSC-Cu2+ complex selectively sense SO3 (2-) over other anions. On addition of Cu2+ to the receptor solution, quenching of emission intensity is observed by 16 folds and upon gradual addition of SO3 (2-) to this solution, the emission intensity increases and the maxima is regained. The limit of detection for Cu2+ detection calculated from fluorescence titration is 1.06 x 10(-8) M and the association constant of PQTSC with Cu2+ is found to be 2.18 x 10(5).
