Fabrication of nanotubes using supramolecular liquid crystal states, their utilization for coating and liquid-crystallization of carbon nanotubes

合成了化合物1((4-(3，4，5-tridodecyloxyphenylmethoxy)-3，5-bis(propenoyloxymethyl)benzoic酸)，并与核心化合物混合得到超分子液晶化合物。对其液晶度进行了鉴定，并对其性能和超结构进行了研究。此外，还合成了它们的同系物，化合物2(4-(3，4，5-trihexadodecyloxy-phenyl-methoxy)-3，5-bis(propenoyloxymethyl)benzoic酸的配合物，并研究了它们的相行为和超结构。作为核心化合物，分别使用了嘧啶、dipyridyl，1，2-dipyridylethane，1-2-dipyridylethene，1，3，5-tris(4-pyridyhnethyloxycarbonyl)benzene.在偏光显微镜下，1与1，2-联吡乙烷和1，2-联吡啶乙烯的2：1络合物和1-with(1，3，5-tris(4-pyridylmethyloxycarbonyl)benzene的3：1络合物均为柱状液晶。将1和2与1，2-联吡乙烷的2：1混合物分别涂覆在玻璃板上，在紫外灯下进行光聚合。X-射线衍射仪研究表明，聚合后1，2-联吡乙烷与1，2-联吡乙烷的2：1混合物的超结构保持不变，而2，2-联吡乙烷的超结构消失。用盐酸洗涤1，2-联吡啶乙烷的聚合物薄膜以去除核心化合物，并用X射线衍射仪进行监测。洗涤后，核心分子被去除，柱直径减小。核心化合物1，2-联吡啶乙烷被放置在薄膜上。然而，核心化合物根本没有被薄膜吸收。然后，1，2-二氨基乙烷被涂在薄膜上并被薄膜吸收。随着客体分子的加入，柱的直径增大。

Compound 1 (4-(3,4,5-tridodecyloxyphenylmethoxy)-3,5-bis(propenoyloxymethyl)benzoic acid) was synthesized and mixed with core compounds to give supermolecular liquid crystalline compounds. The liquid crystallinity was identified and the properties and superstructure were investigated. Further, their homologue, complexes of compound 2 (4-(3,4,5-trihexadodecyloxy-phenyl-methoxy)-3,5-bis(propenoyloxymethyl)benzoic acid) were also synthesized and their phase behaviors and superstructures, were investigated. As the core compounds, were used pyrimidine, dipyridyl,1,2-dipyridylethane,1-2-dipyridylethene,1,3,5-tris(4-pyridyhnethyloxycarbonyl)benzene. The 2:1 complexes of 1 with 1,2-dipyridylethane and 1,2-dipyridylethene, and the 3:1 complex of 1 with(1,3,5-tris(4-pyridylmethyloxycarbonyl)benzene showed columnar liquid crystal phases in polarized optical microscopy. The 2:1 mixture of 1 and 2 with 1,2-dipyridylethane were coated on a glass plate, respectively, and photopolymerized by a UV-lamp. The X-ray diffraction study of the polymers indicated that the superstructure of the 2:1 mixture of 1 and 1,2-dipyridylethane was maintained after the polymerization and that of 2 and 1,2-dipyridylethane was lost. The thin polymer film of 1 with 1,2-dipyridylethane was washed with hydrochloric acid to remove the core compounds, which was monitored by an X-ray diffractometer. After the washing, the core molecules are removed and the column diameter was decreased. The core compounds, 1,2-dipyridylethane, was put on the thin film. However, the core compounds was not absorbed in the film at all. Then, 1,2-diaminoethane was put on the film and absorbed in the filme. The diameter of the columns were increased with inclusion of the guest molecules.
