Abstract

We present here a new example of aggregation-induced emission enhancement (AIEE), which involves an original mechanism based on the formation of organic ion pairs. The phenol 4-hydroxy-7-nitrobenzoxadiazole (NBDOH) is dissociated in water at pH 5.0 to give the corresponding phenolate, which is poorly fluorescent in this medium. We bring evidence that fluorescence quenching is due to an interaction with water molecules. In the presence ...
