• Fast synthesis employing a microwave assisted neat protocol of new monomers potentially useful for the preparation of PDLC films
  作者：M. Teresa Barros、Ana Mouquinho、Krasimira Petrova、Mara Saavedra、João Sotomayor

  DOI：10.2478/s11532-011-0046-2

  日期：2011.8.1

  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.
