摘　　要：Emitters with narrowband spectra are of great importance nowadays because of the growing demand for ultra-high-definition displays in the fields of panel displays and solid-state lighting.Though the reported multiple resonance(MR)emitters have been widely studied with extremely sharp spectra and color-tunable emissions,the electrophilic borylation synthetic strategies and stable narrowband blue devices still face great challenges.
