Benzo[4,5]thieno[2,3-b]pyridine (BTP) was newly developed as an electron deficient moiety for high triplet energy materials and two BTP derivatives with the BTP and carbazole groups were synthesized as high triplet energy bipolar host materials. The BTP derivatives were effective as the host materia...
