Trip the light of plastic : An aqueous fluorogenic sensing system consisting of selective and specific analyte‐triggerable charge‐generation polymers (CGPs) and a negatively charged aggregation‐induced emission active fluorogen (TPE‐COOH 4 ) is presented. In the presence of a triggering analyte of interest, the CGPs undergo electrostatic complexation with TPE‐COOH 4 leading to intense fluorescence emission due to the aggregation of TPE‐COOH 4 .
