简单介绍


ossila材料TSBPA  的详细介绍

4,4'-(Diphenylsilanediyl)bis(N,N-diphenylaniline) (TSBPA) is diphenylsilyl based with two electron donating triphenylamine units. For its electron rich nature, TSBPA is normally used as a high triplet energy hole transport material for blue phosphorescent organic light-emitting diodes (PHOLEDs).

Also due to its electron donating nature, TSBPA can also be used together with electron accepting materials to form exciplex as emitting layer materials. Green PhOLEDs based on TSBPA:PO-T2T exciplex showed TADF emission with close to the maximum theoretical power efficiency and EQE of 60.9 cd/A, 71 Im/W and 20% respectively.
