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.

Organic light emitting polymer comprising light-emitting repeat unit in backbone of polymer and device therewith

Organic Light-Emitting Device An organic light-emitting device () comprising an anode (); a cathode (); a light-emitting layer () between the anode and the cathode; and a hole-transporting layer () between the anode and the cathode, wherein the light-emitting layer comprises a light-emitting compound of formula (I) and the hole-transporting layer comprises a hole-transporting material having a HOMO level that is no more than 5.1 e V from vacuum level: N N ML x R 2 (R) m (R) n y (I) wherein: R in each occurrence is independently a substituent; R 2 is H or a substituent; m is 0, 1 or 2; n is 0, 1, 2, 3 or 4; M is a transition metal; L is a ligand; y is at least 1; and x is 0 or a positive integer.

Organic light-emitting device

An organic light-emitting device comprising an anode; a cathode; a first light-emitting layer between the anode and the cathode; and a second light-emitting layer between the first light-emitting layer and the cathode, wherein:
