The synthesis and phase behaviour of side-chain liquid crystalline polymers containing the trans-azobenzene mesogenic unit are described.Depending on the structure of the repeating unit, the polymers give rise to nematic mesophases and/or different smectic modifications.The liquid crystalline properties of the polymers are discussed with respect to the influence of the polymer backbone nature, chemical constitution and length of the spacer segment, and type and length of the para substituent on the azobenzene moiety.Indications on the UV absorption and photoisomerization behaviour of trans-azobenzene containing polymers are also provided.
