HOLE TRANSPORT MATERIALS, HIGH MOLECULAR COMPOUND FORMED BY POLYMERIZATION OF HOLE TRANSPORT MATERIALS, COMPOSITION FOR ORGANIC ELECTRIC FIELD LIGHT-EMITTING ELEMENT, AND THE ORGANIC ELECTRIC FIELD LIGHT-EMITTING ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide hole transport materials suitable for wet film formation method.;SOLUTION: This invention relates to hole transport materials, expressed by formula (I) the molecular weight range of which is 300 to 5,000. The organic electric field light-emitting element, which comprises an anode, a cathode, and an organic light emitting layer arranged between the two on a substrate, includes a layer containing a high polymer compound fabricated by polymerization of the hole transport materials. Here, R¹ to R⁴ represent hydrogen atoms, and a direct coupling to spacer group Z¹ or monovalent groups; n represents 1 to 4; A1 represents a hydrogen atom or a specific cross-linking group; however, at least one A¹ in a molecule is a cross-linking group; and E¹ is -O-R⁰ or -Ar².;COPYRIGHT: (C)2008,JPO&INPIT
