POLYMERE FÜR OPTISCHE VORRICHTUNGEN

An optical device such as an electroluminescent device is provided which comprises a first contact layer, and a semiconductive layer in contact with the first contact layer. The semiconductive layer comprises an emissive layer of a semiconductive conjugated polymer comprising arylene vinylene units...

More Information
Summary:An optical device such as an electroluminescent device is provided which comprises a first contact layer, and a semiconductive layer in contact with the first contact layer. The semiconductive layer comprises an emissive layer of a semiconductive conjugated polymer comprising arylene vinylene units forming at least part of the polymer main chain, and an electron-withdrawing group is conjugatively linked to the polymer main chain so that the polymer emits radiation when excited to luminesce. Enhanced efficiencies of electroluminescence may be obtained, especially where a hole-transporting polymer forms part of the semiconductive layer.
