BLUE LIGHT-EMITTING POLYMER COMPOUND, ORGANIC ELECTROLUMINESCENT DEVICE AND USE THEREOF

摘要

Disclosed is a light-emitting material which is thermally more stable and exhibits high luminous efficiency and high durability when used as a blue light-emitting material for an EL device. Specifically disclosed is a blue light-emitting polymer compound characterized by containing a structural unit derived from a compound represented by the following formula (1). (1) (In the formula (1), R1-R4 and R11-R14 independently represent a hydrogen atom, a substituent or an electron-withdrawing substituent, and at least one of R1-R4 and at least one of R11-R14 independently represent an electron-withdrawing substituent; and R5-R8 and R15-R18 independently represent a hydrogen atom or a substituent.In this connection, one of R11-R18 is a substituent having a polymerizable carbon-carbon double bond.)
