Abstract
Official abstract text for this publication.
Compounds comprising a 3,9-linked oligocarbazole moiety and a dibenzothiophene, dibenzofuran, dibenzoselenophene, aza-dibenzothiophene, aza-dibenzofuran, or aza-dibenzoselenophene are provided. The 3,9-linked oligocarbazole and dibenzo or aza-dibenzo moiety are separated by an aromatic spacer. The compounds may be used as non-emissive materials for phosphorescent OLEDs to provide devise having improved performance.
