    摘要: A method of aligning liquid crystal material by bringing into contact with a thin layer of polymer which contains the anthracenyl group, the polymer having previously been treated with plane polarised ultraviolet light. A liquid crystal cell is described wherein each of the substrates defining two opposing cell walls are coated on their inner surface with a suitable polymer for carrying out the invention. A typical embodiment of the invention would have repeat unit (II). ##STR1##

    摘要: This invention relates to an organic semiconductor device comprising a substrate bearing an organic layer sandwiched between electrode structures wherein the organic layer comprises a polymer of general Formula (I): wherein X is selected from H, CN, F, Cl, Br, COOCH3. Y is given by the following general Formula (II): wherein A is a phenyl group which may be further substituted in 1 or 2 or 3 positions with groups independently selected from C1-8 alkyl, CN, F, Cl; B and C are both phenyl groups which may be further substituted, independently of each other, in 1 or 2 or 3 or 4 or 5 positions with groups independently selected from C1-8 alkyl, CN, F, Cl; A, B and C may also be, independently of each other, selected from pyrimidine, pyridazine and pyridine; m=5-20,000.
