  New Liquid-Crystalline Elastomers: 1. Synthesis, Structure, and Phase Behavior of a Series of Mesogenic Crosslinking Agents Containing Reactive Bifunctional Groups

  摘要：

  The synthesis of eight mesogenic crosslinking agents (1c-8c) containing reactive bifunctional groups is described. The chemical structures were characterized by Fourier transform infrared (FTIR) and 1H nuclear magnetic resonance (NMR) spectra. The mesomorphism was investigated by differential scanning calorimetry (DSC) and polarizing optical microscopy (POM). The compounds 1c, 2c, 3c, 5c, 6c, and 8c showed an enantiotropic nematic phase. In addition, 5c exhibited a smectic A (SmA) phase on cooling; 4c exhibited a smectic C (SmC) phase, a SmA phase, and a nematic phase and a monotropic a smectic B (SmB) phase on cooling. 7c revealed an SmA phase and a nematic phase and a monotropic SmC phase on cooling.

  The crosslinkable nematic polyorganosiloxanes are cyclic polyorganosiloxanes containing at least three different mesogenic side groups per polyorganosiloxane, where at least two mesogenic side groups per polyorganosiloxane each contain at least three radicals selected from aromatic, heteroaromatic and cycloaliphatic radicals. They contain a methacrylic or acrylic group in at least one of the mesogenic side groups. The cyclic polyorganosiloxanes have a broad nematic phase and can be readily aligned.

  The present invention relates to liquid-crystalline compounds and to a process for preparing liquid-crystalline polyorganosiloxanes having methacryloxy and/or acryloxy groups by the reaction of organosiloxanes having hydrogen atoms bonded directly to silicon atoms and/or organosilanes which can be condensed to form organosiloxanes having hydrogen atoms bonded directly to silicon atoms, with alkenes and/or alkynes having mesogenic groups, which comprises reacting in a first step the organosiloxanes with an alkene and/or alkyne having at least one non-enolic hydroxyl group protected by a protective group, and in a second step the protective group is removed and the hydroxyl group which is now free is esterified with (meth)acrylic acid, esters, anhydrides and/or halides thereof and thereafter optionally condensing the organosilanes to organosiloxanes.

• Side-Chain Cholesteric Liquid Crystalline Elastomers Derived from a Mesogenic Cross-Linking Agent

  DOI：10.1021/ma034915k

  日期：2003.12.1

  The synthesis of the two monomers M-1 and M-2 and a series of new side-chain cholesteric liquid crystalline elastomers P-2-P-8 is presented. The chemical structures of the monomers and elastomers obtained were confirmed by FTIR or H-1 NMR spectroscopy. The cross-link density of the elastomers was determined by swelling experiments. The mesomorphic properties were investigated by differential scanning calorimetry (DSC), thermogravimetric analyses (TGA), polarizing optical microscopy (POM), and X-ray diffraction (XRD) measurements. Monomer M-1 showed a cholesteric phase, and M-2 revealed smectic and nematic phases. The effect of the cross-link density on the phase behavior Of P-2-P-8 is discussed. Elastomers P-2-P-6 containing less than 12 mol % of the cross-linking units displayed elasticity, reversible liquid crystalline phase transition, wide mesophase temperature ranges, and high thermal stability. Elastomer P-7 displayed stress-induced birefringence, and P-8 showed only elasticity with no other texture. Experimental results demonstrated that the glass transition temperatures increased, and the isotropization temperatures and the mesophase temperature ranges Of P-2-P-6 decreased with increasing cross-link density.
