Heterocyclic compounds and their use in electro-optical or opto-electronic devices

摘要

Compounds exhibiting high hole mobility and/or high glass transition temperatures together with favourable HOMO, LUMO and triplet levels are provided which are 2-(4'-Diphenylamino)phenyl-8-(1'-thianthrenyl)- dibenzothiophene and 4-(1-Thianthrenyl)-bis(triphenylamine). The compounds may be used for hole transport layers e.g. in OLED devices.
