  硫醇-烯化学制备的基于聚硅氧烷的液晶聚合物和弹性体

  摘要：

  通过将介晶单体通过硫醇-烯点击化学接枝到聚[3-巯基丙基甲基硅氧烷]（PMMS）上，已经合成了具有聚硅氧烷骨架的一系列侧链液晶聚合物（LCP）。通过组合1对它们的性质进行了详细研究1 H NMR，凝胶渗透色谱，热重分析，差示扫描量热法，偏振光学显微镜和小角X射线散射。与需要贵金属催化剂铂的传统氢化硅烷化方法相比，这种新设计的硫醇-烯方案可在良性条件下生产仅含反马尔科夫尼科夫加成产物的基于聚硅氧烷的LCP。此外，通过控制PMMS和介晶单体的摩尔比，可以将PMMS基LCP进行部分功能化，同时保留剩余的巯基，这些巯基可以进一步用作交联位点，以制备聚硅氧烷基液晶弹性体（LCE）。除了制备向列向各向同性转变温度时最大收缩率为42％的LCE纤维外，

  In recent years, sequence-controlled side-chain liquid crystal polymers (SCLCPs) have gained extensive interest because mesogenic units with different lengths and distributions can form various ordered sequences, which further endow LCP materials with diverse functions. In this manuscript, a side-chain side-on maleimide-containing monomer 2,5-bis-(4-butoxybenzoyloxy)-benzoic acid 6-(2,S-dioxo-2,S-dihydro-pyrrol-1-yl)-hexyl ester (Y1801) and a side-chain end-on styrene-containing monomer 4'-[6-(4-vinyl-phenoxy)-hexyloxy]-biphenyl-4-carbonitrile (Y1802) are combined in one single macromolecular chain and orderly polymerized in an alternative sequence to form an alternating copolymer Poly(Y1801-alt-Y1802). The chemical structure and alternating sequence of Poly(Y1801-alt-Y1802) are confirmed by GPC and NMR techniques. The combination of DSC, POM, and WAXS data indicates that, although the side-on homopolymer PY1801 and the end-on homopolymer PY1802 both exhibit the nematic phase, their alternating copolymer Poly(Y1801-alt-Y1802) shows an interdigitated smectic A phase, a compromised molecular arrangement instead. In addition, a strong fluorescence emission of Poly(Y1801-alt-Y1802) is observed, which might provide this novel alternating-structured liquid crystal polymer with potential applications in luminescent materials and devices.
