摘要：

Organosoluble polyimides were synthesized with the alicyclic dianhydride 1,8-dimethylbicyclo[2,2,2]oct-7-ene-2,3,5,6-tetracarboxylic dianhydride and aromatic diamines. The polyimides possessed good solubility both in strong dipolar solvents and in common solvents; the thermal decomposition temperature of the polyimides exceeded 420 degreesC. Strong and flexible films of the polyimides, with the cutoff of ultraviolet-visible absorption lower than 310-320 nm, exhibited good features as the alignment layers for nematic liquid crystals with pretilt angles of 1.5-2.9 degrees.
