An electroluminescent device is provided incorporating an emissive layer comprising a processible polymer matrix such as poly(methylmethacrylate) and a chromophoric component such as an asymmetric stilbene or distyrylbenzene. The chromophoric component is blended with the polymer matrix or covalently attached thereto as a side chain and is selected to emit radiation in the region 400 nm to 500 nm when excited to luminesce.
提供了一种电致发光装置,其中包含一层发光层,该发光层包括可加工的聚合物基质,例如聚甲基丙烯酸甲酯,以及一种色团成分,例如不对称的苯乙烯或二烯基苯。色团成分与聚合物基质混合或共价地附着在侧链上,并被选择为在激发发光时发射400nm至500nm范围内的辐射。
