Synthesis and Characterization of Liquid Crystalline Monomers and Side-Chain Polymers Containing Diphenyldiacetylene Mesogens

Nine unsymmetrically diphenyldiacetylenic monomers were prepared.The phase behavior as well as thermal polymerization of the obtained monomers were characterized by optical polarizing microscopy and DSC measurement.UV absorption, refractive indices and dielectric constants of the monomers were also measured.The olefinic monomers were subjected to undergo hydrosilylation reaction with poly(methylhydrogensiloxane) to form the polysiloxanes.Thermal behavior of the prepared polysiloxanes were studied.

Synthesis of Three Phenolic Pent-1-en-4-ynes

Three novel pent-1-en-4-ynes 3, 4 and 5, analogues of the naturally-occurring rooperol 2, have been synthesized.The procedure involves initial protection of the phenolic groups as allyl ethers followed by deprotection with Wilkinson's catalyst.
