Novel Design Strategy of Multiple-Resonance-Type Blue Fluorescent Dopants with High Efficiency and High Color Purity

Student

Description:

Deep blue boron based MR type fluorescent materials were synthesized and evaluated. Benzo[b]thiophene substituent which has low triplet energy was introduced to lower triplet energy to suppress the intermolecular interactions. Further, bis(4-(tert-butyl)phenyl)amine was introduced to control the wavelength, color purity, and molecular distance. The DABNA-BzTh-DPA based device showed CIEy coordinates of 0.087 and external quantum efficiency of 7.9%.
