摘要：

A novel family of electron-transporting hole blockers, 1,3-bis[5-(dimesitylboryl)thiophen-2-yl]benz and 1,3,5-tris[5(dimesitylboryl)thiophen-2-yl]benzene (TMB-TB), were designed and synthesized. They were found to exhibit multiple redox behavior in electrochemical reduction and to readily form stable amorphous glasses with high glass-transition temperatures above 100 degreesC. TMB-TB was proven to function well as a hole blocker in blue-emitting organic electroluminescent devices.
