  Synthesis of the Organic/Inorganic Hybrid Star Polymers and Their Inclusion Complexes with Cyclodextrins

  摘要：

  In this study, we synthesized a series of the organic/inorganic hybrid star PCLs. These star PCLs can form inclusion complexes (ICs) with alpha- and gamma-CD, but not with beta-CD. These CD ICs were characterized by XRD, solid-state C-13 CP/MAS NMR spectroscopy, H-1 NMR spectroscopy, FT-IR spectroscopy, DSC, and TGA. Our results suggest that the PCL chains of these star polymers lose their original crystalline properties and were included inside the channels provided by the CDs to form a columnar crystalline structures. The stoichiometries (PCL:CD) that we determined by H-1 NMR spectroscopy for all of the ICs with alpha- or gamma-CD are higher than those of the corresponding CD/linear PCL ICs because of the steric hindrance around the bulky POSS core, which causes some of the c-caprolactone units near the core to be free from complexation with the CDs. From these analyses, we proposed some possible structures for the CD/star PCL ICs.

  In this work, a new family of polyhedral oligomeric silsesquioxanes (POSS) based esters have been synthesized that consists eight ester functional groups. These are classified into Type-I and Type-II esters based on the starting materials, octakis(3-chloropropyl)silsesquioxane (Cl-POSS) and octakis(3-hydroxypropyldimethylsiloxy) octasilsesquioxane (OHPS) respectively. These new POSS type ester moieties can be used as insulating oils and oil additives in the transformers and also considered to be alternatives to mineral and vegetable oils that are presently used in the insulation system.

  We present a novel hybrid cationic polymer based on polyhedral oligomeric silsesquioxanes (POSS). This is the first report of using a cationic POSS-based material for gene delivery. Due to its amphiphilic properties, hydrophobic drugs such as paclitaxel can be encapsulated within the hydrophobic core of this polymer. In this paper, it is shown that paclitaxel-encapsulated hybrid POSS-based polyplexes show superior gene transfection efficiency in human breast cancer cells than the non drug-loaded polyplexes.

  我们提出了一种基于多面体低聚硅倍半氧烷（POSS）的新型阳离子聚合物。这是首次报道使用基于阳离子POSS的材料进行基因传递。由于其两亲性，疏水性药物（如紫杉醇）可以封装在这种聚合物的疏水核心中。本文表明，与未加载药物的聚复合物相比，紫杉醇封装的基于POSS的混合聚复合物在人类乳腺癌细胞中显示出卓越的基因转染效率。
• Star-shaped POSS-polycaprolactone polyurethanes and their shape memory performance

  Star-shaped polyhedral oligomeric silsesquioxane (SPOSS)-based multi-arm poly(ε-caprolactones) (PCLs) with various arm lengths were synthesized by ring opening polymerization of ε-caprolactone. Increasing the PCL arm lengths was observed to increase the melting temperature and also the melt crystallization temperature in SPOSS-PCLs. Star-shaped POSS-PCL polyurethanes (SPOSS-PUs) were then prepared by cross-linking SPOSS-PCLs with hexamethylene diisocyanate (HMDI) and their shape memory (SM) behaviour was determined. For this purpose two cyclic thermo-mechanical testing concepts with similar programming (deformation and shape fixing) but different recovery strategies (free strain versus fixed-strain constrained stress recovery) were used and the synthesized polymers were systematically investigated around the crystallization and melting temperatures of PCL. SPOSS-PU with the highest POSS content exhibited remarkable cycles-averaged (N = 2–5) shape fixities and strain recoverabilities of 98% and stress recoverabilities close to 100%. The main structural factors that were expected to reduce the SM performances with increasing PCL arm lengths were a lowering of cross-link density (content of octasubstituted POSS) and an increase in chain flexibility/molecular mobility.

  通过ε-己内酯的环开聚合反应，合成了具有不同臂长的星形多面体寡聚倍半硅氧烷（SPOSS）基多臂聚（ε-己内酯）（PCL）。研究发现，增加PCL的臂长可以提高SPOSS-PCL的熔融温度和熔融结晶温度。然后，通过六亚甲基二异氰酸酯（HMDI）与SPOSS-PCL交联，制备了星形POSS-PCL聚氨酯（SPOSS-PU），并确定了其形状记忆（SM）特性。为此，我们使用了两种循环热力学测试概念，它们具有相似的编程（变形和形状固定），但不同的恢复策略（自由应变与固定应变约束应力恢复），并对合成的聚合物进行了系统研究，围绕PCL的结晶和熔融温度。POSS含量最高的SPOSS-PU表现出显著的循环平均（N = 2-5）形状固定性和应变恢复性（98%），应力恢复性接近100%。随着PCL臂长的增加，预计会降低SM性能的主要结构因素是交联密度（八取代POSS的含量）降低和链柔性/分子流动性增加。

  New low‐temperature curable organic/inorganic hybrid polymers were designed and synthesized as gate dielectrics for organic thin‐film transistors (OTFTs). Allyl alcohols were introduced to polyhedral oligomeric silsesquioxane (POSS) via hydrosilyation to produce an alcohol‐functionalized POSS derivative (POSS‐OH). POSS‐OH was then reacted with hexamethoxymethylmelamine at carrying molar ratios at 80

  设计并合成了新型的低温可固化有机/无机杂化聚合物，作为有机薄膜晶体管（OTFT）的栅极电介质。通过氢化硅烷化将烯丙醇引入多面体低聚倍半硅氧烷（POSS）中，生成醇官能化的POSS衍生物（POSS-OH）。然后在催化量的对甲苯磺酸存在下，在80°C下使POSS‐OH与六甲氧基甲基三聚氰胺以摩尔比反应，得到高度交联的网络聚合物（POSS‐MM）。制备的薄膜在热交联反应后光滑且坚硬，漏电流极低（<10 -8 A / cm 2）在可见光谱范围内无明显吸收。与使用热交联聚（乙烯基苯酚）和三聚氰胺作为栅极介电层（0.18 cm 2 / /）的器件相比，使用合成绝缘体作为栅极介电层的基于并五苯的OTFT具有更高的空穴迁移率（高达0.36 cm 2 / Vs）。VS）。©2014 Wiley Periodicals，Inc.
