AN ORGANIC LIGHT-EMITTING DEVICE USING A COMPOUND HAVING A CARRIER TRANSPORT PROPERTY AND A PHOSPHORESCENT PROPERTY

摘要

Disclosed is an organic light-emitting device which contains one or more organic layers sandwiched between an anode and a cathode, wherein at least one of the organic layers is a light-emitting layer comprising a polymer compound (I), the polymer compound (I) comprising structural units derived from a hole transport or electron transport and phosphorescent polymerizable compound (a1) and structural units derived from a polymerizable compound (b) capable of transporting an oppositely charged carrier, the polymerizable compound (a1) being selected from the group consisting of the following formulae (E1-1) and the like.
