Electroluminescent device comprising a chromophoric polymeric composition
First Claim
1. An electroluminescent device incorporating an emissive layer comprising a processible polymer matrix and a chromophoric component which emits radiation in the region of 400-500 nm when excited to luminesce, wherein the chromophoric component is blended with the polymer matrix or covalently attached thereto as a side group and is selected from stilbene or distyrylbenzene, where at least one ring of stilbene or distyrylbenzene is substituted with a solubilizing group.

Abstract
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.
