  Synthesis and structures of triptycene-derived Tröger's base molecular clips

  摘要：

  A series of triptycene-derived Troger's bases with molecular clip shaped structures have been conveniently and efficiently synthesized by one-pot condensation of corresponding amino-substituted triptycenes with paraformaldehyde in the presence of trifluoroacetic acid, and their structures have been characterized by NMR, MALDI-TOF MS spectra, elemental analyses and single-crystal X-ray diffraction.

  本征微孔性的基于三萜烯的聚合物：可以针对气体吸附量身定制的有机材料

  摘要：

  我们报告了固有的微孔性（network-PIMs）网络聚合物的合成和性质，该聚合物来自具有连接至其桥头位置的烷基的三茂基单体。可以通过烷基链的长度和支链来控制气体的吸附，从而使材料的表观BET表面积可以在618-1760 m 2 g -1的范围内进行调整。。较短的（例如甲基）或支链的（例如异丙基）烷基链提供了最大的微孔性，而较长的烷基链似乎阻止了由刚性有机骨架产生的微孔。与其他PIM相比，增强的微孔性源自骨架的大分子形状，这是由三萜烯单元决定的，这有助于减少刚性骨架的延伸平面支柱之间的分子间接触，从而降低了填充在骨架内的效率。坚硬的。对于具有低或中等压力（在1 bar / 77K下为1.83质量％；在18 bar / 77 K下为3.4质量％）的纯有机材料，具有甲基或异丙基取代基的三茂基PIM的氢吸附能力是最高的。 ）。

  is presumably due to the preorganization of the rigid spacers, the cooperation between charge‐transfer interactions of rigid spacers, and the complexation of the binding motifs. Furthermore, the intermolecular photoinduced electron transfer (PET) between rigid spacers in these robust complexes could be switched on and off by modulating their complexation through acid–base reactions, which is reminiscent

  通过使用互补的刚性间隔基（蒽与1,4,5,8-萘二酰亚胺（NDI））和两对[24] crown-8醚和仲二烷基铵官能团作为结合基序，成功构建了两个坚固的二价络合物。结果表明，正确选择的刚性间隔基比柔性间隔基更有效地实现强大的多价缔合。据推测，这是由于刚性间隔基的预组织，刚性间隔基的电荷转移相互作用之间的协作以及结合基序的复杂化所致。此外，这些坚固的配合物中刚性间隔基之间的分子间光诱导电子转移（PET）可以通过酸碱反应调节它们的络合而被打开和关闭，这让人想起能够进行电子转移的插头插座系统。此外，与包含NDI作为间隔基的二价客体络合后，以蒽为间隔基的二价主体的自增敏光氧化作用可被完全抑制。也可以通过调用分子间PET来理解该过程，并且可以通过酸碱反应打开和关闭该过程。这些坚固的配合物的光物理和光化学特性已被解释为带有报警系统的分子键盘锁。因此，双插头插座系统和分子键盘锁成功地集成在了坚固的多价系

  Six 5,9,14,18‐tetrathiaheptacene derivatives (1 a–1 f) were synthesized by using a simple ether–ether exchange reaction and fully characterized. In contrast to the planar conformation usually observed in thiophene‐fused benzene systems, single‐crystal analysis indicates that 7,16‐dipropyl‐5,9,14,18‐tetrathiaheptacene (1 a), 7,16‐diphenyl‐5,9,14,18‐tetrathiaheptacene (1 b), and 7,16‐di(4′‐chlorophenyl)‐5

  通过简单的醚-醚交换反应合成了六种5,9,14,18-四硫杂庚烯衍生物（1 a – 1 f），并进行了充分表征。与通常在噻吩-熔融苯系统中观察到的平面构象相反，单晶分析表明7,16-二丙基-5,9,14,18-四噻庚烯（1 a），7,16-二苯基-5,9 ，14,18-四硫庚烯（1b）和7,16-di（4'-氯苯基）-5,9,14,18-四硫庚烯（1 c）采用椅子构象。1 a，1 b和1 c时，蒽与末端苯单元之间形成的二面角为137.258、137.855和134.912°分别接近理论优化结果（1 b时为128° ）。有趣的是，7,16-二（三氟甲基苯基）-5,9,14,18-四硫杂庚烯（1 e）的氧化产物呈鞍形，这导致在单晶中形成圆柱状单元。苯基侧基上的取代基对其UV / Vis吸收光谱的影响较小，但可以在发射光谱中观察到明显的红移，这是分子内电荷转移的原因。电化学测量表明，所有化合物均出现两个氧化波。基于1
• Rational Design of Intrinsically Ultramicroporous Polyimides Containing Bridgehead-Substituted Triptycene for Highly Selective and Permeable Gas Separation Membranes

  Highly ultramicroporous, solution-processable polyimides bearing 9,10-bridgehead-substituted triptycene demonstrated the highest BET surface area reported for polyimides (840 m(2) g(-1)) and several new highs in gas selectivity and permeability for hydrogen (1630-3980 barrers, H-2/CH4 similar to 38) and air (230-630 barrers, O-2/N-2 = 5.5-5.9) separations. Two new dianhydrides bearing 9,10-diethyl- and 9,10-dipropyltriptycenes indicate that the ultramicroporosity is optimized for fast polymeric sieving with the use of short, bulky isopropyl bridgeheads and methyl-substituted diamines (TrMPD, TMPD, and TMBZ) that increase intrachain rigidity. Mechanically, the triptycene-based analogue of a spirobisindane-based polyimide exhibited 50% increases in both tensile strength at break (94 MPa) and elastic modulus (2460 MPa) with corresponding 90% lower elongations at break (6%) likely due to the ability of highly entangled spiro-based chains to unwind. To guide future polyimide design, structure/property relationships are suggested between the geometry of the contortion center, the diamine and bridgehead substituent, and the mechanical, microstructural, and gas transport properties.
