摘要：

Chiral discotic liquid crystalline polymers are of interest because of their similarity to helical polymers, and for a comparison with chiral rod-shaped liquid crystals. They are now accessible in several forms, e.g. by doping achiral donor polymers with chiral acceptors (see Figure). The chirality of the discotic phases was investigated CD-spectroscopically on thin films.
