控制超分子有机纳米管的壁厚在层次结构、尺寸和表面积方面是重要的。我们已经成功地选择性制备单壁不对称纳米管的配位/解离的Pt（II）配合物与羧基轴承bola两亲物。bola两亲物的常规pH调节产生多壁纳米管。有趣的是，顺铂或transplatin与bola两亲物的配位在中间组装中表现出acis-transefect，除去Pt（II）产生相同的单壁不对称纳米管。此外，内配位的顺铂-纳米管可以用作铂纳米颗粒的软模板。
Control of the wall thicknesses of supramolecular organic nanotubes is important in terms of the hierarchy, dispersibility, and surface areas. We have succeeded in the selective preparation of single-walled asymmetrical nanotube by the coordination/dissociation of Pt(II) complexes with a carboxylic-bearing bolaamphiphile. Conventional pH-adjustment of the bolaamphiphile yields multiple-walled nanotube. Interestingly, the coordination of cisplatin or transplatin with the bolaamphiphile demonstrate acis–transeffect in intermediate assemblies, removal of the Pt(II) yields the same single-walled asymmetrical nanotubes. Further, the endo-coordinated cisplatin-nanotube can serve as a soft template for platinum nanoparticles.
