  A New Family of Polymerizable Lyotropic Liquid Crystals:  Control of Feature Size in Cross-Linked Inverted Hexagonal Assemblies via Monomer Structure

  摘要：

  An efficient and versatile synthesis of a series of polymerizable amphiphilic mesogens that affords control over tail length and position of the :polymerizable group is described. The synthesis employs a novel and facile method of preparing styrene ethers. The monomers are sadium salts of styrene ether-modified fatty acids that can be used to form cross-linkable inverted hexagonal (H-II) lyotropic liquid crystal (LLC) phases at ambient temperature with controllable nanometer-scale dimensions. Examination of a series of regioisomers with the same alkyl chain length but with the styrene: ether group at different locations along the chain revealed that the position of the styrene ether has a profound effect on the dimensions of the resulting HII phase at a fixed temperature and composition. Increasing overall monomer tail length also has a significant, although smaller, effect on the unit cell dimensions of the LLC phase. By controlling the structure of the LLC monomer in this manner, cross-linked HII phases with interchannel distances (ICD) ranging from 29 to 54 Angstrom can be obtained. Furthermore, changing the counterion from Na+ to tetraalkylammonium ions leads to further expansion of the H-II unit cell to a maximum ICD of 65 Angstrom, as well as to the production of a lamellar phase. Use of these monomers affords a new and unparalleled degree of control over phase structure and dimensions for the production of nanostructured organic materials.

• Tandem Isomerization/Hydroformylation/Hydrogenation of Internal Alkenes to <i>n</i>-Alcohols Using Rh/Ru Dual- or Ternary-Catalyst Systems

  A one-pot three-step reaction, isomerization/hydroformylation/hydrogenation of internal alkenes to n-alcohols, was accomplished by employing a Rh/Ru dual-catalyst system. By using a combination of Rh(acac)(CO)2/bisphosphite and Shvo's catalyst, (Z)-2-tridecene was converted to 1-tetradecanol in 83% yield with high normal/iso selectivity (n/i = 12). The method was applicable to other internal alkenes

  内烯烃异构化/加氢甲酰化/加氢生成正醇的一锅三步反应是通过使用Rh/Ru双催化剂体系完成的。通过使用 Rh(acac)(CO)2/二亚磷酸酯和 Shvo 催化剂的组合，(Z)-2-十三烯以 83% 的产率转化为 1-十四醇，具有高正/异选择性 (n/i = 12)。该方法适用于其他内部烯烃，包括功能化烯烃，如烯醇和烯酸酯。此外，第三种组分 Ru3(CO)12 的加入有效地提高了油酸甲酯串联异构化/加氢甲酰化/氢化中的 n/i 比（从 n/i = 1.9 到 4.4）。对照实验表明异构化是由 Rh 和 Ru 介导的，并且 Rh 和 Ru 的共存对于 H2/CO 下醛的加氢是必不可少的。

  The biocatalytic hydroxylation of fatty acids is an appealing reaction, but the generation of over-oxidation by-products and the lack of selectivity hampers its transfer to industry. Now a highly selective and efficient peroxygenase has been engineered for the production of hydroxy fatty acids through a synthetic procedure that can be rapidly adapted to the preparative scale.

  脂肪酸的生物催化羟基化是一个吸引人的反应，但过度氧化副产物的产生和选择性的缺乏阻碍了它向工业的转移。现在，一种高选择性和高效的过氧化酶已被设计用于通过可快速适应制备规模的合成程序来生产羟基脂肪酸。
