  Synthesis and Characterization of Siloxane Contained Liquid Crystalline Polymers with Two Symmetric Mesogens

  摘要：

  New thermotropic siloxane contained liquid crystalline polymers with two symmetric mesogens were prepared by hydrosilation with Rh(PPh(3))(3)Cl catalyst. It was found that Rh(PPh(3))(3)Cl catalyst was effective for low molecular weight polymerization. The resulting polymers exhibited good solubility in organic solvents such as tetrahydrofuran(THF), chloroform, and so on. The structures of the monomer and polymers were confirmed by IR, H-1 and C-13 NMR spectra The number average molecular weight(<(Mn)over bar>) values of the polymers were in the range of 2000 similar to 6000. Thermal properties of the monomers and the polymers were analyzed by differential scanning calorimetry(DSC), and polarized optical microscopy. Monomers did not show liquid crystalline phase but the polymers exhibited nematic phases.

  glass transition temperature of the polymer block to −25 from +20 °C, the Tg when an alkyl spacer was used. Although no distinct LC phase was observed with the polyoxyethylene spacer when MPOB was used, when BPP4 was attached via a polyoxyethylene spacer, a distinct liquid crystalline transition was observed. Polymers with an alkyl spacer exhibited liquid crystalline behavior and good phase segregation

  The monosubstituted ferrocene derivatives, omega-[4-(4-methoxyphenoxycarbonyl) phenoxy]alkoxycarbonyl ferrocene, were synthesized in order to compare the liquid crystallinity to that of disubstituted ferrocene derivatives, 1,1'-bis[omega-[4-(4-methoxyphenoxycarbonyl) phenoxy] alkoxycarbonyl] ferrocene. Some of the monosubstituted ferrocene derivatives containing relatively longer flexible spacer showed the liquid crystalline phase, nematic and/or smectic phases. The crystal structure of 2-[4-(4-methoxyphenoxycarbonyl) phenoxy] ethoxycarbonyl ferrocene was determined by X-ray diffraction method using a single crystal. The molecular structure revealed a bent structure that is almost a half of "Z'' shaped molecular structure of 1,1'-bis[2-[4-(4-methoxyphenoxycarbonyl)phenoxy]ethoxycarbonyl]ferrocene.
