| 概 要 | Development of luminescent materials is a hot topic of current interest because of their applications to the development of fluorescence sensing and light-emitting diodes. The relationship with structures and light emission property of a series of aryl-substituted pyrroles was studied during aggregation. Compared the optical properties and aggregated structures of these pyrroles, it is suggested that the more twisted configuration which prevented parallel orientation of conjugated chromophores, combining with restricted intramolecular rotations (RIR) effect was the main cause the aggregation-induced emission (AIE) or aggregation-induced emission enhancement (AIEE) phenomenon. Due to introduction of carboxylic groups, triphenylpyrrole salts with AIE property as chemosensor are used to high-sensitively, high-selectively, turn-on detect Al3+ ion in the aqueous solution. |
