The present invention comprises a conjugated polymer for optoelectronic devices, comprising a structural unit of formula (I) or formula (II):-[A-D1-A-D2]n-&#x2003;&#x2003;(I)-[A1-D1-A2-D2]n-&#x2003;&#x2003;(II)wherein A is an acceptor group; A1 and A2 are acceptor M groups which differ from one another; D1 and D2 are donor groups which differ from one another; and n is an integer between 30 and 1000.

Conjugated polymers

A light emitting device comprising: an anode; a cathode; a light emissive layer located between the anode and the cathode, said light emissive layer comprising a charged metal complex for emitting light and a counterion or counterions with sufficient charge to balance the change on the charged metal complex; characterized in that the counterion or counterions are substantially immobile so (that light output from the device is immediate, provided that the combined charged metal complex and counterion do not have General Formula: (I) or (II); where C&#x2014;N is a cyclometallated liquid.

Light-emitting device

A light emitting device comprising an anode, a cathode, a light emissive layer located between the anode and the cathode, said light emissive layer comprising a compound for emitting light, said compound comprising a metal complex and X, said metal complex containing a metal (M) and a phosphorous atom that is coordinated directly to M, and an aryl or heteroaryl group Arthat is directly bonded to the phosphorous atom, where Aris substituted with X, and characterized in the X comprises an aryl or heteroaryl group.

Metal complex

A method of forming an electroluminescent device comprising the steps of:
