In order to control and stabilize the liquid crystalline behaviour, and hence the self-organization, the polymerization process can be effectively used. Mesogenic units incorporated into the backbones as functional side-chains of weakly cross-linked macromolecules can become orientationally ordered. Several new calamitic reactive mesogens possessing the vinyl terminal group with varying flexible chain lengths and with/without lateral substitution by the methyl (methoxy) groups have been designed and studied. Depending on molecular structure, namely the type and position of lateral substituents, the resulting materials possess the nematic, the orthogonal SmA and the tilted SmC phases structure of mesophases was confirmed by SAXS. The main objective of this work is to contribute to better understanding of molecular structure – mesomorphic property relationship for new functional reactive mesogens aimed for further design of smart self-organizing macromolecular materials.
