One of the most exciting classes of photosensitive organic materials that is able to self-assemble at nano-scopic scale are those exhibiting the LC behaviour which can be distantly tuned by external stimulus. Under UV light irradiation, the photoisomerisation process can be reversible in case of N=N or cinnamoyl group. However, the compounds possessing the cinnamoyl fragment with C=C double bond are capable of both photoisomerisation and photocycloaddition. Cinnamoyl-based reactive mesogens with polymerizable vinyl group were designed, their mesomorphic and structural behaviour were studied. Under UV irradiation the rod-like cinnamoyl-based molecules are transformed to cross-linked ones the process is irreversible. The main objective is to contribute to better understanding of molecular structure – mesomorphic property relationship for functional cinnamoyl-based photosensitive reactive mesogens which can be used for design of smart self-assembling macromolecular materials.
