摘要: Herein, a new fluorescence turn-on chemosensor 2-(4-(1, 2, 2-triphenylvinyl) phenoxy) acetic acid (TPE-COOH) specific for Al³⁺ was presented by combining the aggregation-induced-emission (AIE) effect of tertaphenylethylene and the complexation capability of carboxyl. The introduction of carboxylic group provides the probe with good water-solubility which is important for analyzing biological samples. The recognition toward Al³⁺ induced the molecular aggregation and activated the blue fluorescence of the TPE core. The high …
