The major findings in the growing field of aggregation induced emissive (AIE) active materials for the detection of environmental toxic pollutants have been summarized and discussed in this Review article. Owing to the underlying photophysical phenomenon, fluorescent AIE active molecules show more impact on sensing applications. The major focus in current research efforts is on the development of AIE active materials such as TPE based organic fluorescent molecules, metal organic framework, and polymers that can be employed for the detection of toxic pollutants such as CN − , NO 2 − , Hg 2+ , Cd 2+ , As 3+ , As 5+ , F − , Pb 2+ , Sb 3+ ions.

“…The former usually introduces anions with negative charge to the side chain, using electrostatic attraction to realize detection 14 . The latter selects heteroatoms with coordination ability to provide recognition sites of metal ions, which leads to significant changes in optical signals 15 . These conjugated polymers containing heterocycles can be divided into main‐chain type and side‐chain type according to the different ways in which the coordination units are connected on the conjugated backbone.…”

A novel conjugated polymer PFCZ‐IM containing 2‐(thiophen‐2‐yl)‐1H‐benzo[d]imidazole units was synthesized and characterized. The basic photophysical properties of the polymer and its fluorescence recognition behaviors toward metal ions and amino acids were investigated. In the study of the response of metal ions, PFCZ‐IM had high sensitivity to Fe3+, Ag+ and Cu2+, which significantly quenched the fluorescence of the polymer. The binding of the 2‐(thiophen‐2‐yl)‐1H‐benzo[d]imidazole moiety to Cu2+ was investigated by density functional theory calculation. Interestingly, [PFCZ‐IM‐Cu2+] also exhibited outstanding characteristics of fluorescence ‘turn on’ in the presence of cysteine (Cys), as the interaction between Cu2+ and Cys caused the polymer to dissociate from the complex. In particular, addition of 30 μmol L–1 of Cys can increase the Cu2+‐quenching fluorescence of PFCZ‐IM by 34.8 times with short response time, demonstrating that [PFCZ‐IM‐Cu2+] has tremendous potential in the actual detection of Cys. This polymer is expected to be utilized for dual fluorescence detection of specific metal ions and Cys. © 2021 Society of Industrial Chemistry.
