  High purity synthesis of a polyhedral oligomeric silsesquioxane modified with an antibacterial

  摘要：

  Here, high purity octa(3-mercaptopropyl) POSS has been synthesized and subsequently reacted with a variety of alkenes via radical and base catalyzed thiol-ene addition reactions. Among them a unique antibacterial agent, eugenyl methacrylate (EgMA), was attached yielding an organic soluble octaEgMA-POSS compound as a potential antibacterial additive for polymeric systems.

  dendrimer was initially prepared from octamercaptopropyl-substituted polyhedral oligomeric silsesquioxane (POSS) and diethyl allylmalonate by a photochemical thiol–ene reaction. The POSS dendrimer was used as a ligand to coordinate with lanthanide ions (Eu3+ and Tb3+) to form hybrid luminescent complexes. The resulting hybrid lanthanide complexes were incorporated into the PMMA matrix via in situ polymerization

  最初由八巯丙基取代的多面体低聚倍半硅氧烷（POSS）和烯丙基丙二酸二乙酯通过光化学硫醇-烯反应制备了一种新型的β-二酮官能化POSS树状聚合物。POSS树状聚合物用作配体，与镧系元素离子（Eu 3+和Tb 3+）配位，形成杂化发光复合物。通过原位聚合将所得杂化镧系元素络合物掺入到PMMA基质中。形态学研究表明，这些杂化复合物组装成直径约100 nm的球形颗粒，并且可以很好地分散在PMMA基质中。所得的基于POSS的混合发光PMMA表现出高度饱和的颜色和良好的热稳定性。

  Through UV-initiated thiol-ene click chemistry, carbazole-substituted ladder-like structured polysilsesquioxane and cage-structured polyhedral oligomeric silsesquioxane (T8-POSS) compounds were synthesized and fully characterized. Perfectly carbazole-substituted T8-POSS was synthesized via post-modifications of a mercaptopropyl T8-POSS, while the ladder polysilsesquioxane was synthesized through a base-catalyzed hydrolysis-polycondensation reaction with a carbazole-substituted trialkoxysilane monomer. Through a comparative evaluation of the thermal, mechanical, and photophysical properties of the synthesized compounds, we demonstrate the utility and superiority of the ladder-like structure over the T8-POSS material.

  通过紫外光引发的硫醇-烯点击化学反应，合成了咔唑取代的梯状结构聚硅烷基二氧杂环戊烷和笼状结构的多面体低聚硅烷基二氧杂环戊烷（T8-POSS）化合物，并对其进行了全面表征。完全咔唑取代的 T8-POSS 是通过对巯丙基 T8-POSS 进行后修饰合成的，而梯状聚硅烷基quioxane 则是通过碱催化与咔唑取代的三烷氧基硅烷单体进行水解-缩聚反应合成的。通过对合成化合物的热性能、机械性能和光物理性能进行比较评估，我们证明了阶梯状结构比 T8-POSS 材料更实用、更优越。
