有機膜及び有機エレクトロルミネッセンス素子及び感光体

Organic film, organic electroluminescent element and photoreceptor

Abstract

PROBLEM TO BE SOLVED: To improve the luminous characteristics of an organic electroluminescent element and the photosensitivity of a photoreceptor by using an organic film comprising a specified phenanthridine derivative for the hole transfer layer or luminescent layer. SOLUTION: A hole injection electrode (anode) comprising an indium-tin oxide, a luminescent layer which comprises a phenanthridine derivative having diphenylamino groups, represented by formula I wherein R1 to R3 are each alkyl (-Cn H2n+1 ) (wherein n is 1 to 10), cyano, amino, alkoxyl, halogeno, H, or a group of formula II or III [wherein R is H or Cn H2n+1 (wherein n is 1 to 10)]} and has a film thickness of about 500Å, an electron transfer layer which comprises an oxazole derivative of formula IV and has a film thickness of about 500Å, and an electron injection electrode (cathode) which comprises an Mg-In alloy (at a ratio of about 10:1) and has a film thickness of about 2,000Å are formed into films in order on a transparent glass base plate to give an organic electroluminescent element. A voltage is applied to bias the hole injection electrode plus and the electron injection electrode minus.
