New Liquid Crystalline Methacrylate Polymers Containing 4-Methacryloylox-yphenoxy Group and 4'-((S)-(+)-2-Methylbutoxy)biphenyl-4-carboxyl Mesogenic Group:1.Synthesis and Characterization of the Monomers

摘要

New two kinds of methacrylate monomers having a benzene ring inserted between spacer and meth-acryloyl group and the chiral center connected to the terminal of the mesogenic structures were synthesized.In these two series the effects for the formation of the liquid crystals in regard to the length changes of the spacers and mesogenic groups were investigated.The first series did not show any liquid crystalline phases in the intermediate compounds nor in the end products.However,the methacrylates of second series showed the liquid crystalline phases in the intermediate compounds as well as in the final products regardless of the length of the spacers.
