Elektroaktive Polymere und daraus hergestellte Geräte

Electroactive polymers and devices made therefrom

Polymères électroactifs et dispositifs fabriqués à partir de ceux-ci


An organic block polymer useful in an electroluminescent polymer device, comprising: (a) an emissive polymer block that is consistently conjugated along the backbone of the emissive polymer block; and (b) a positive charge carrier polymer block that is consistently conjugated along the backbone of the positive charge carrier polymer block for transporting positive charge carriers to the emissive polymer block so that the positive charge carriers can combine with negative charge carriers to generate light.
