主　　题：aggregation-induced emission heavy metal detection hydrogel 

摘      要：A“turn-onfluorescent sensing strategy was developed for ultrasensitive detection of heavy metal mercury ion(Hg2+)directly in *** utilized an aqueous soluble aggregation-induced emission(AIE)-active probe,named 1,1,2,2-tetrakis(4-(1Htetrazol-5-yl)phenyl)ethene(TPE-4TA),composing of a luminescent tetraphenylene core and multiple anionic tetrazolate *** probe retained dark when molecularly dissolved in ***,mercury ions can ligate with multiple tetrazolate groups to form infinite coordination polymer particles spontaneously,thus inducing a fluorogenic AIE response for in situ ***,by embedding this AIE sensing molecules in a hydrophilic polyvinyl alcohol substrate,the resulting hydrogel film allowed in situ detection of Hg^(2+)on a laser-induced fluorescence analysis setup in aqueous *** strategy worked effectively in common aqueous environments with pH from 4 to 7.5 and showed high sensitivity(limit of detection down to 0.38 ppb/1.9 nM),good selectivity and a wide linearity range for *** work may lead to a reliable and promising platform for on-site environmental water analysis.
