Abstract
Polymers contain, as mesogenic groups, groups which produce a discotic phase, and furthermore can contain pleochroic dyes. The novel polymers possess novel properties, and combinations of properties, which the conventional polymers which form liquid-crystalline phases do not possess. The polymers can be used in electro-optical displays, in storage elements, as electrically or photo-electrically conductive polymers and as strain sensors.
