Let there be more light! TPA-substituted anthracene derivatives result in stable organic light-emitting diodes. The more balanceable hole and electron transport in TPA-substituted anthracene, together with the easier hole-injection and hole-trapping mechanism, leads to high electroluminescence efficiency (see picture; ETL: electron transport layer; HTL: hole transport layer).
