Title:
新規なアリールアミン含有ビニルポリマーおよびそれを用いた有機エレクトロルミネッセント素子
Document Type and Number:
Japanese Patent JP4608044
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To develop an arylamine-containing vinyl monomer and a novel arylamine-containing vinyl polymer which is obtained by polymerizing the monomer and has a high glass transition temperature, and to provide, by substituting the polymer for the conventionally used low molecular aromatic amines, a novel organic EL(electroluminescent) element which prevents the destruction of the element structure through recrystallization or agglomeration and the deterioration of the element during storage at a high ambient temperature. SOLUTION: An arylamine-containing vinyl monomer is represented by formula I (wherein R1 is hydrogen or an alkyl group; R2 and R3 are each independently a group chosen from a group consisting of hydrogen, a methyl group and an ethyl group; and Ar1 and Ar2 are each independently a group chosen from a group consisting of aromatic groups optionally having substituents). An arylamine-containing vinyl polymer is obtained by polymerizing this and has a number average molecular weight of from 1,000 to 1,000,000. An organic EL element is prepared using this polymer.
