PHENYLPHENOXAZINE OR PHENYLPHENOTHIAZINE BASED COMPOUNDS AND ORGANIC ELECTROLUMINESCENCE

摘要

A phenylphenoxazine or phenylphenothiazine-based compound is provided to ensure excellent hole transfer capability due to delocalized electron distribution and to improve thermal stability due to high glass transition temperature by having a phenyl phenoxazine or a phenyl phenothiazine substituent in a nitrogen atom of phenyl benzidine. A phenylphenoxazine or phenylphenothiazine-based compound is represented by the chemical formula 1. In the formula 1, R 1~R9 which are the same or different, represent hydrogen, halogen, cyano group, hydroxyl group, substituted or non-substituted C1-20 alkyl group, substituted or non-substituted C3-20 cycloalkyl group, substituted or non-substituted C5-30 heterocycloalkyl group, substituted or non-substituted C1-20 alkoxy group, substituted or non-substituted C6-30 aryl group, substituted or non-substituted C6-30 aralkyl group, and substituted or non-substituted C2-30 heteroaryl group; X is O or S; Ar1 and Ar2 are substituted or non-substituted C6-30 aryl group and substituted or non-substituted C2-30 heteroaryl group.
