Phenylcarbazole compounds and organic electroluminescence devices using the same

Abstract

A phenylcarbazole compound of formula (1) below is provided, where each of Rand Ris independently a monosubstituted or polysubstituted functional group selected from the group consisting of hydrogen atom, a substituted or unsubstituted C-Calkyl group, a substituted or unsubstituted C-Caryl group, a substituted or unsubstituted C-Cheterocyclic group, a substituted or unsubstituted C-Ccondensed polycyclic group, wherein groups adjacent to Rand Rbind and form a saturated or unsaturated cyclic hydrocarbon group, and Ar is a substituted or unsubstituted C-Caryl group or a C-Cheteroaryl group, wherein the substituent Ris defined herein. Also included is an organic electroluminescence device comprising the above phenylcarbazole compounds.
