Patent ID: 10439147

Abstract:
Compounds exhibiting high hole mobility and/or high glass transition temperatures are provided which are of the formula [Ar1]m[Ar2]n wherein:      Certain of the compounds may be used in electron transport layers and may be doped with p-type dopants. They may be incorporated into OLEDs, organic photovoltaic devices, imaging members and thin film transistors.In further embodiments there are provided OLEDs or other devices e.g. electrostatic latent image forming members in which improved efficiency is obtained by using as electron transport layers, electron injectors, hosts and emitters (dopants) ambipolar or electron-transmitting compounds in which thianthrene is bonded to aryl e.g. 1-anthracenyl-9-yl-thianthrene, 1-biphenyl-4-yl-thianthrene and 9,10-Bis(1-thianthrenyl) anthracene.
