NEW TRIPHENYLENE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT ELEMENT USING SAID DERIVATIVE |
摘要 |
Triphenylene derivatives represented by the following general formula (1), wherein Ar1 and Ar2 are aromatic groups. The compounds have a structure in which an aromatic tertiary amine is introduced into a triphenylene ring. Owing to this structure, the compounds exhibit (A) favorable hole injection property, (B) large hole mobility, (C) excellent electron blocking power, (D) stability in their thin-film form, and (E) excellent heat resistance. The compounds are useful as hole-transporting materials for use in the organic EL devices. |
