Abstract:

In this study, a new type of luminogen with aggregation-induced-emission (AIE) behavior was designed and synthesized. The result of single-crystal X-ray structure showed a planar structure in which the dihedral angle between two aromatic rings is less than 30o. Moreover, two different intermolecular hydrogen bond interactions supported the stability of the crystal structure. After the formation of organic nanoparticles in poor solubility solvent, the emission intensity of the desired product was increased and the enhancement achieved was 14-fold. This new design of luminogen provided further understanding of the AIE mechanism.

Keywords: Aggregation-induced-emission, benzothiazole, cyanovinyl, fluorescence enhancement, organic nanoparticle
