Paper Abstract

Banana-shaped molecules have been prepared and their mesophase behavior was investigated. The constitution of the fiber-ring compounds was varied, e.g. with the type and direction of connecting groups and, especially, the influence of substituents situated at different positions of the angled middle part. According to preliminary investigations by x-ray measurements, polarizing microscopy and mixing behavior several mesophases could be distinguished. Ferroelectricity could be detected only for one of the phases by electro-optical switching and pyroelectrical investigation.
