  Synthesis and Characterization of Siloxane Contained Liquid Crystalline Polymers with Two Symmetric Mesogens

  摘要：

  New thermotropic siloxane contained liquid crystalline polymers with two symmetric mesogens were prepared by hydrosilation with Rh(PPh(3))(3)Cl catalyst. It was found that Rh(PPh(3))(3)Cl catalyst was effective for low molecular weight polymerization. The resulting polymers exhibited good solubility in organic solvents such as tetrahydrofuran(THF), chloroform, and so on. The structures of the monomer and polymers were confirmed by IR, H-1 and C-13 NMR spectra The number average molecular weight(<(Mn)over bar>) values of the polymers were in the range of 2000 similar to 6000. Thermal properties of the monomers and the polymers were analyzed by differential scanning calorimetry(DSC), and polarized optical microscopy. Monomers did not show liquid crystalline phase but the polymers exhibited nematic phases.

  用于选择性检测和轻松去除汞的基于硫醚的荧光共价有机框架 (II)

  摘要：

  重金属离子具有剧毒，作为环境污染物广泛传播。正在开发新的策略来同时检测和去除这些有毒离子。在此，我们利用共价有机框架 (COF) 的内在优势，开发了用于传感应用的荧光 COF。作为概念验证，一种硫醚功能化 COF 材料 COF-LZU8 “自下而上”与多功能性集成，用于选择性检测和轻松去除汞 (II)：作为信号传感器的 π 共轭框架，均匀且密集分布的硫醚基团作为 Hg(2+) 受体，有利于实时检测和传质的规则孔，以及用于循环使用的稳健 COF 结构。COF-LZU8在高灵敏度方面实现了优异的传感性能，出色的选择性、易于查看和实时响应。同时，从水中有效去除Hg(2+)和COF-LZU8的回收为实际应用提供了可能。此外，X 射线光电子能谱和固态核磁共振调查证实了 Hg(2+) 和 COF-LZU8 的硫醚基团之间的强和选择性相互作用。这项研究不仅证明了荧光 COFs 在感测和去除金属离子方面的应用，而且还强调了功能化

  Chiral C-2-symmetric 2,5-bisamide hydroquinone ligands, with beta-amino alcohols as chiral building units, were synthesized in excellent overall yields. The ligands gave up to 54.4% ee in the palladium-catalyzed 1,4-dialkoxylation of 1,3-dienes. These findings demonstrate the potential of asymmetric induction utilizing chiral benzoquinones as ligands in palladium(II) catalysis, albeit with modest enantiomeric excesses. Weakly coordinating hydroxyl groups of the ligand appear to be crucial for the success of the reaction. Mechanistic aspects and the origin of enantioselectivity are also discussed.

As a proof-of-concept, a thioether-functionalized COF material, COF-LZU8, was "bottom-up" integrated with multifunctionality for the selective detection and facile removal of mercury(II): the π-conjugated framework as the signal transducer, the evenly and densely
