Carbon Nanocluster -hybrid Super Molecules -Design, Thin Film Formation and the Development of Their Novel Functions-

本研究的目的是构建碳纳米管基杂化纳米材料。碳纳米管与有机、无机和高分子材料的结合，可能会导致构建高性能的脐带纳米碳材料。所得结果总结如下：碳纳米管被发现可以溶解在含有几种携带芳香基团的两亲体的溶剂中，这些芳香基团包括蒽基、苯基和芘基。通过核磁共振、紫外可见近红外光谱和拉曼光谱对纳米管溶液进行了表征。我们在聚苯乙烯-马来酸酐中引入了芳香族基团。通过原子力显微镜、紫外可见近红外光谱、核磁共振和拉曼光谱对合成的共聚物进行了表征，发现它们是“活性碳纳米管增溶剂”，可用于设计和构建具有特定功能的碳纳米管/聚合物复合纳米材料。我们已经报道了双链DNA在水溶液中溶解swnt。通过在石英衬底上交替吸附聚(dC)-SWNTs和聚(dG)-SWNTs，成功地形成了DNA/碳纳米管薄膜。所得DNA-SWNTs薄膜的紫外-可见-近红外光谱显示，在500-600nm和1000- 1400nm区域分别可分配给met-SWNTs和sem-SWNTs。经过50次吸附循环后，DNA-SWNTs薄膜显示出基底上SWNTs的特征拉曼峰。

The aims of this study are the construction of carbon nanotube-based hybrid nanomaterials. The combination of carbon nanotubes and organic, inorganic and polymer materials may lead to the construction of navel nano carbonmaterials with high performances. The obtained results are summarized as follows.Carbon nanotubes are found to dissolve individually insolvents containing several kinds of amphiphiles carrying an aromatic moiety including anthryl, phenathryl and pyrenyl groups. The sollubilized nantube solutions were characterized by NMR, UV vis-near IR and Raman spectra.We have introduced an aromatic moiety to poly(styrene-alt-maleic anhydride). The synthesized copolymers were characterized by atomic force microscopy, UV-vis-near IR,NMR and Raman spectra and found that they act as "reactive carbon nanotube solubilizers" that should be useful for the design and construction of SWNTs/polymer composite nanomaterials with specific functions.We have already reported that double-stranded DNA dissolves SWNTs in aqueous solutions. DNA/carbon nanotube films were successfully formed by the alternating adsorption of poly(dC)-SWNTs and poly(dG)-SWNTs onto a quartz substrate. UV-vis-near IR spectra for the obtained DNA-SWNTs films showed absorption bands in the region of 500-600nm and 1000-1400 nm that are assignable to met-SWNTs and sem-SWNTs, respectively. The DNA-SWNTs films after the adsorption cycle of 50 times showed characteristic Raman peaks derived from the SWNTs on the substrate.
