    摘要:
    硅氧烷基砌块的受控组装为二氧化硅基多孔材料的设计架构提供了一种合理的方法。此处报道了一种非水热法,由笼型低聚硅氧烷制备微孔晶体的方法。通过氢键辅助的有序组装以及随后的甲硅烷基化的分子间连接来形成晶体。用二甲基硅烷醇基团修饰了具有双四环(D4R)结构的笼式硅氧烷。二甲基硅烷醇基团的分子间氢键导致形成由D4R单元组成的柱状结构。通过将硅烷醇基团与三氯硅烷直接甲硅烷基化,将晶体中的相邻笼架桥起来,从而实现了一种保留原始有序排列的新型晶体微孔材料。

The first method was based on the subsequent hydrosilylation of two alkenes in a one-pot manner, whereas the second one consisted of a two-step protocol in which intermediates (RSiMe2O)∼4(HSiMe2O)∼4Si8O12 were isolated and then reacted with the second alkene, in the presence of the same or a different catalyst. Resulting systems due to the presence of two

    作者:Kyeong-Min Choi、S.J. Harshavardhan、Ch. Sridhar、B.V.D. Vijaykumar、Deepak Kumar、Kiwan Jang、Man-Sig Lee、Dong-Soo Shin

    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.
