  Toward Synthetic Tubes for NO₂/N₂O₄:  Design, Synthesis, and Host−Guest Chemistry

  摘要：

  Design of molecular nanotubes is proposed for entrapment and conversion of NO2/N2O4 gases. Synthesis of 1,3-alternate bis-calix[4]arene tube 3 of 5 x 11 Angstrom internal dimensions is presented, and its reversible reactions with NO2/N2O4 in solution are studied. Exposure of 3 to NO2/N2O4 in chlorinated solvents results in the rapid encapsulation of nitrosonium (NO+) cations within its interior. Mono- and dinitrosonium complexes 4 and 5, respectively, were isolated and characterized by UV-vis, FTIR, and H-1 NMR spectroscopies, and also molecular modeling. The NO+ entrapment process is reversible, and addition of water quickly recovered starting tube 3. Encapsulated within the tube NO+ species act as nitrosating agents for secondary amides. These findings open wider perspectives toward NO2/NOx storing and converting materials and also offer a promise for further development of supramolecular chemistry of synthetic nanotubes.

  We report the synthesis and encapsulation properties of long (up to 5 nm) molecular nanotubes 1-4, which are based on calix[4]arenes and can be filled with multiple nitrosonium (NO(+)) ions upon reaction with NO(2)/N(2)O(4) gases. These are among the largest nanoscale molecular containers prepared to date and can entrap up to five guests. The structure and properties of tubular complexes 1(NO(+))(2)-4(NO(+))(5)

  我们报告长（可达5纳米）分子纳米管1-4的合成和封装性能，这些纳米管基于杯[4]芳烃，与NO（2）反应后可充满多个硝基（NO（+））离子）/ N（2）O（4）气体。这些是迄今为止制备的最大的纳米级分子容器，最多可容纳五名客人。管状配合物1（NO（+））（2）-4（NO（+））（5）的结构和性质通过溶液中的UV / Vis，FTIR和（1）H NMR光谱进行了研究，还通过分子建模。NO（+）截留在1（NO（+））（2）-4（NO（+））（5）中是可逆的，添加[18] crown-6可以快速恢复起始管1-4。FTIR和滴定数据表明，较长的试管中NO（+）的结合增强，这可能是由于协同作用所致。所述的纳米管可以用作存储和转化NO（x）的材料，并且还有望进一步发展分子容器的超分子化学。这些发现也为合成碳纳米管作为碳纳米管的替代品的应用开辟了广阔的前景。
