通过测量由三个交联桥连接的α-环糊精和偶氮苯修饰的聚乙二醇组成的分子纳米管混合物的诱导圆二色性，研究了分子纳米管与线性聚合物在溶液中的包合-解离行为.结果发现，在室温下形成的纳米管和线性聚合物之间的包合配合物，并随着温度的升高，聚合物从纳米管解离，如理论上预期的。
We have investigated the inclusion-dissociation behavior between molecular nanotubes and linear polymers in solutions by measuring the induced circular dichroism of the mixture of the molecular nanotubes, which are composed of α-cyclodextrins linked by three cross-linking bridges, and poly(ethylene glycol) modified with azobenzene. It was found that the inclusion complex between the nanotubes and the linear polymers was formed at room temperature, and that the polymers were dissociated from the nanotubes with increasing temperature, as expected theoretically.
