Abstract

original image

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-COOH4) is presented. In the presence of a triggering analyte of interest, the CGPs undergo electrostatic complexation with TPE-COOH4 leading to intense fluorescence emission due to the aggregation of TPE-COOH4.
