Abstract: | It has been reported that the length of the molecular chain and the rigidity of molecules influence the structure of the polymer
network in PDLC films and hence the electro-optical properties of the composites. Herein, a series of new aromatic monomeric
monomethacrylates, bismethacrylates and monovinylbenzene derivatives with a mesogenic core were successfully synthesized under
microwave irradiation. The microwave assisted synthesis resulted in decreased reaction times, reduced solvent requirement,
increased operational simplicity, and in most cases, improved yields and selectivity.
