摘要：

A doped coumarin based photoalignment polymer is irradiated with polarised UV light and used to macroscopically orient a light-emitting photoreactive mesogen. This is subsequently crosslinked to form an electroluminescent nematic polymer network. The photoluminescence order parameter of the nemtatic is discussed in terms of the photoalignment conditions.
