The exquisite integration of ESIPT,PET and AIE for constructing fluorescent probe for Hg(Ⅱ)detection and poisoning
文献摘要：
Excessive mercury ions(Hg2+)in the environment can accumulate in human body along with the food chain to cause serious physiological reactions.The fluorescence probes were considered as conve-nient tool with great potential for Hg2+detection.Most existing probes suffer from aggregation-induced quenching(ACQ)effects and insufficient sensitivity.Herein,a novel type of fluorophore was developed by combining the aggregation-induced emission(AIE)and excited state intramolecular proton transfer(ES-IPT)characteristics.Subsequently,a phenyl thioformate group with photoinduced electron transfer(PET)effect was connected to give an efficient"turn-on"probe(HTM),which exhibited good selectivity toward Hg2+,short response time(30 min),coupled with extremely low detection limit(LOD=1.68 nmol/L).In addition,HTM was used successfully in real samples,cells and drug evaluation,underlying the superiority of HTM to detect Hg2+in practical applications.
