Design Strategies of Fluorescent Dopant for Enhanced Photoluminescence Quantum Yield and Suppressed Dexter Energy Transfer

Student

Description:

In this work, we developed novel fluorescent materials, BFD01, BFD02, and BFD03, by incorporating benzothiophene into the multiple resonance structure of boron-nitrogen compound. BFD02 achieved a maximum external quantum efficiency of 8.6% in fluorescent devices by high photoluminescence quantum yield and BFD03 achieved an impressive external quantum efficiency of 18% in hyperfluorescence devices as a terminal emitter by suppressing Dexter energy transfer through bulky blocking groups.
