73‐1: Invited Paper: Decoration Strategy in Para Boron Position: An Effective Way to Achieve Ideal Multi‐Resonance Emitters

Abstract

Narrowband, full‐color, and quenching‐resistant emitters are urgently needed for the next generation high‐resolution displays. Though the flourishment of narrowband multiple resonance (MR) emitters in blue region, these materials still face thorny challenges such as effective light‐color regulation strategies and concentration‐induced spectral broadening/emission quenching. Herein, we highlight the research status of an effective "decoration strategy for para B position". On one hand, the introduction of an electron donor or acceptor could induce a hypochromatic‐ or bathochromic‐shift emission respectively without undesirable FWHM broadening. On the other hand, a more advanced molecular motif is further proposed through adopting a peripheral benzene ring on the para position of the B‐substituted phenyl in MR core to construct the high‐purity, highefficiency, quenching‐resistant and stable MR emitters. Such concept is expected to provide a possible way for the modification, optimization and expansion of MR emitters to meet more possible applications.
