Organic light-emitting polymer and device

摘要

A light-emitting polymer comprising a light-emitting repeat unit in a backbone of the polymer, wherein the polymer has an anisotropy of no more than 0.8 and wherein a transition dipole moment of the light-emitting repeat unit is aligned with the polymer backbone. The light-emitting unit is a fluorescent repeat unit, such as a fluoranthene repeat unit or a phosphorescent repeat unit. The fluoranthene fluorescent repeat unit is used as an isomer mixture for forming an aligned light-emitting repeat of formulae: Also disclosed, is a method of forming a polymer comprising a light-emitting repeat unit in a backbone of the polymer and an organic light-emitting device comprising the said polymer.
