| Abstract: | The chemical syntheses of 12 new azo dyes are reported. The optically active compounds were prepared by the Mitsunobu reaction, amide formation, and esterification with optically active alcohols or acids. Several new compounds showed liquid-crystalline properties, and their phase transition behavior was investigated. |
