英文摘要: A series of peripheral dendron-incorporating 1,4-bis[2,2-bis(4-alkoxyphenyl)vinyl] benzenes with aggregation-induced emission properties were synthesized. As the generation of the dendrons increased, there was an enhancement in the fluorescence emission of the corresponding fluorophore not only in the solid state but also in various solvent systems. The fluorescence quantum yields of the molecule with the largest dendons were up to 71% in the solid state and 66% in solution. The dendrons acted as a shell to the fluorophore core to prevent intermolecular pi-pi interactions and restrict the intramolecular rotations of the fluorophore, which improved the luminous intensity. This study shows that the incorporation of bulky dendrons is an effective way to increase the fluorescence emission efficiency of aggregation-induced emission fluorophores.
