【 摘 要 】

A series of blue fluorescent materials containing electron accepting pyrimidine and electron donating bis(biphenyl)amine, diphenylcarbazole, and diphenylindolo[3,2,1-jk]carbazole moieties were synthesized in moderate yields, and their optical and electrochemical properties were investigated. Diphenylindolo[3,2,1-jk]carbazole was revealed to be a promising building block for deep blue fluorescent materials with a very narrow full width at half maximum. (C) 2021 Elsevier Ltd.
