  固有特性的微孔聚合物，源于Tröger碱的碳环类似物

  摘要：

  Tröger的碱（TB）由于具有刚性的双环V形结构，经常被用作合成本征微孔聚合物（PIM）的基础材料。在这项研究中，PIM结构中的TB成分被2,3：6,7-二苯并双环[3.3.1]壬烷（一种纯粹的TB碳环类似物）取代。如使用氮吸附所确定的，这种修饰仅导致微孔量略微减少。与以前报道的PIM的进一步比较表明，该建筑单元（因此TB）在生成固有的微孔性方面比螺双双辛烷（PIM合成中常用的结构单元）的效率明显降低。似乎2,3：6,7-二苯并双环[3.3.1]壬烷和TB单元的V形允许聚合物链之间更紧密的接触，从而提高包装效率。

• Design and Synthesis of Polyimides Based on Carbocyclic Pseudo-Tröger’s Base-Derived Dianhydrides for Membrane Gas Separation Applications

  Two novel carbocyclic pseudo-Troger's base-derived dianhydrides, 5,6,11,12-tetrahydro-5,11-methanodibenzo [a,e][8]annulene-2,3,8,9-tetracarboxylic anhydride (CTB1) and its dione-substituted analogue 6,12-dioxo-5,6,11,12-tetrahydro-5,11-methanodibenzo [a,e][8]annulene-2,3,8,9-tetracarboxylic dianhydride (CTB2), were made and used for the synthesis of soluble polyimides of intrinsic microporosity with 3,3'-dimethylnaphthidine (DMN). The polyimides CTB1-DMN and CTB2-DMN exhibited excellent thermal stability of similar to 500 degrees C and high BET surface areas of 580 and 469 m(2) g(-1), respectively. A freshly made dione-substituted CTB2-DMN membrane demonstrated promising gas separation performance with O-2 permeability of 206 barrer and, O-2/N-2 selectivity of 5.2. A higher O-2 permeability of 320 barter and lower O-2/N-2 selectivity of 4.2 were observed for a fresh CTB1-DMN film due to its higher surface area and less tightly packed structure as indicated by weaker charge-transfer complex interactions. Physical aging over 60 days resulted in reduction in gas permeability and moderately enhanced selectivity. CTB2-DMN exhibited notable performance with gas permeation data located between the 2008 and 2015 permeability/selectivity upper bounds for O-2/N-2 and H-2/CH4.
