ELEKTROAKTIVE POLYMERE UND DARAUS HERGESTELLTE GERÄTE

摘要

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 at least one of the following:
(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
(c) a negative charge carrier polymer block that is consistently conjugated along the backbone of the negative charge carrier polymer block for transporting negative charge carriers to the emissive polymer block so that the negative charge carriers can combine with positive charge carriers to generate light, and
(d) a host polymer block that is consistently conjugated along the backbone of the host block for providing a matrix for emitter that affords Forster energy transfer and minimization of concentration quenching effects The emissive block copolymer comprises a fluorine group and a diazine group fused to a ring benzene ot a to a thiophene group, the positive charge carrier polymer block comprises a fluorene group and a triarylamine group, and the host polymer block contains a fluorene group.
