  Broad Molecular Ribbons of Nanometer Size Composed of Biphenyl Units

  摘要：

  The new tetrafunctionalized biphenyl key building blocks 16 and 39 led, for the first time, to the hitherto broadest molecular ribbons that contain biphenyl units in a transverse arrangement by iterative synthetic methods. The length and breadth of the molecular ribbons, as single chemical entities, are diversified. They can be used as cyclization precursors in the synthesis of long molecular tubes of type 2 with a large diameter. The solubility and the host-guest behavior (clathrate formation with benzene, dimethylformamide, and dichloromethane) of these nanometer-size molecular ribbons were optimized by the introduction of various side chains (benzenesulfonamide, 4-toluenesulfonamide, and 4-terf-butylbenzenesulfonamide groups) into the skeleton of the ribbons. New 14-, 15-, and 16-membered model ring systems (compounds 20a, 22a, and 24 respectively) were synthesized in order to examine the constitution of the 16-membered diaza[3.3]-phane 18a. Nanometer-size tube-shaped molecules 7a, 7b and 8 were obtained by cyclization of tetrafunctionalized molecular ribbons with the biphenyl building block. The constitution and conformation of the molecular ribbons and belts were proven by NOE experiments and X-ray analyses.

  由支链低聚物构建的金属-有机框架

  摘要：

  已经研究了由低聚物或聚合物有机配体制备的金属有机框架 （MOF），分别称为 oligoMOF 和 polyMOFs。在此，描述了几种 oligoMOFs，它们是由具有树突状或星状结构的支链低聚物制备的。制备了具有四个 （4（H2bdc）-b） 或八个 （8（H2bdc）-b） 1,4-苯二羧酸 （H2bdc） 基团的支链寡聚配体，用于合成等网状型 Zn（II） 基 MOF （IRMOF）。与 IRMOF-1 或先前描述的 oligoMOF 相比，支链四聚体 （4（H2bdc）-b） 产生的 oligoIRMOF-1 具有更高的环境稳定性。为了了解配体结构的影响，还从线性四聚体 （4（H2bdc）-l） 制备了 oligoIRMOFs。对于支链八聚体 （8（H2bdc）-b），发现需要添加有机碱基才能产生结晶寡核苷酸 IRMOF。多变量 MOF （MTV-MOFs） 也可以用八聚体 （8（H2bdc）-b）
