We have investigated the performance of a class of heterocycles, 5, 10-dihetera-5,10-dihydroindeno[3,2b]indenes, as hole transport agents in simple double heterostructure organic light-emitting diodes with tris(8-hydroxyquinoline)aluminum (Alq). The best of these materials, 5,10-dihydroindolo[3,2b]indole, yields devices with luminance and lifetimes comparable to those obtained using N,N{prime}-di-(3-methylphenyl)-N,N{prime}diphenyl-4,4{prime}-diaminobiphenyl (TPD) as a hole transporting material.
