Aggregation effects on the one- and two-photon excited fluorescence performance of regioisomeric anthraquinone-substituted perylenediimide

Abstract

Regioisomerism is an efficient strategy for finely tuning the structures of molecules in the isolated or the aggregated state. Herein, two regioisomers of perylene diimide (PDI) derivatives have been designed and synthesized. The positions of the substituent anthraquinone groups display distinct influences on their molecular conformation and aggregate structures, resulting in different fluorescence properties upon one- and two-photon excitation. In addition, owing to the bright emission, cellular imaging tests based on their nanoparticles were also conducted.
