Abstract

Abstract: A fluorescent sensor TPE-TSC with aggregation induced emission (AIE) characteristic is synthesized for detecting Hg 2+ by attaching thiosemicarbazide (TSC) unit into tetraphenylethylene (TPE) group. TPE-TSC exhibits intense green emission in DMSO/H2 O (V:V = 1:9) solution with the formation of the aggregation. TPE-TSC shows outstanding fluorescence quenching toward Hg 2+ over other metal ions due to the formation of complex TPE-TSC/Hg 2+ with a 2:1 binding ratio. The detection limit of TPE-TSC for Hg 2+ is 1 × 10 −5 mol·L −1 . Graphical Abstract:
