  Two New Series of Coordination Polymers and Evaluation of Their Properties by Density Functional Theory

  摘要：

  以 4,4′-二甲氧基-3,3′-联苯二甲酸为有机连接剂，通过溶热法合成了 CPO-68-M（M = Zn、Mn 和 Co）和 CPO-69-M（M = Ca 和 Cd）等五种新型配位聚合物（CPs）。三维框架由被连接剂分隔的金属羧酸链构成。结构分析表明，CPO-68-M 和 CPO-69-M 都具有窄菱形通道和 sra 拓扑结构的致密网络。这两个系列的氯化石蜡在结构上的主要区别在于金属配位多面体，CPO-68-M 和 CPO-69-M 的金属配位多面体分别为四配位和八配位。这两种氯化石蜡结晶度高、坚固，具有良好的热稳定性（> 350 °C）。鉴于 CPs 与 MIL-53 在拓扑结构上的相似性，我们测试了 CPs 在气体刺激下是否会表现出类似的柔性结构响应。密度泛函理论（DFT）建模用于评估氯化石蜡在较大压力范围内作为气体吸附材料的潜力。密度泛函理论分析的结论是，氯化石蜡由于其结构刚性而不适合气体吸附。不过，电子结构计算显示 CPO-68-M 和 CPO-69-M 是间接带隙半导体，估计带隙在 2.49 和 2.98 eV 之间。

  Self-assembly of vesicles from the stacking of a dipodal F⋯H–N hydrogen bonded arylamide foldamer

  摘要：

  In this paper, we report the synthesis and self-assembling behavior of an F center dot center dot center dot H-N hydrogen bonding-induced arylamide-based dipodal foldamer. SEM, AFM. TEM, and XRD studies reveal that this preorganized oligomer stacks to form vesicles in methanol-chloroform (10-70%) binary solvents due to the strong stacking interaction of the folded segments and the supramolecular polymeric feature of the dipodal molecule in the stacked state. In contrast, a simple folded molecule can give rise to vesicles only when the chloroform content is 45-55%. (C) 2009 Elsevier Ltd. All rights reserved.

  A new coordination polymer was synthesized hydrothermally using 4,4’-dimethoxy-3,3’-biphenyldicarboxylic acid (H2dmbpdc) and Ca(NO3)2∙4H2O. The structure of the new compound, Ca(dmbpdc)(H2O)2 (CPO-70-Ca), was determined from powder X-ray diffraction (PXRD) data using simulated annealing, followed by Rietveld refinement of the structure. The framework is based on one-dimensional metal carboxylate chains
