| Summary: | In search of new thermotropic, photoswitchable materials, a number of 4′-alkoxy-4-(ω-cinnamoylalkoxy)azobenzenes were prepared. The synthetic procedure included <i>O</i>-alkylation of 4-nitrophenol, followed by reduction of the nitro group (H<sub>2</sub>, Pd/C), diazotization of the aniline, and subsequent reaction with ω-hydroxyalkoxybenzenes, followed by a modified Appel-type esterification (BrCCl<sub>3</sub>, PPh<sub>3</sub>). The photochemical behavior of the substances was investigated. |
