Abstract

The inclusion behavior between molecular nanotubes and linear polymer chains in aqueous solutions is experimentally investigated by measuring the optical absorption spectra of the solutions with iodine as a probe. It is found that the amount of polymer chains included into nanotubes increases with polymer length, which indicates a molecular recognition of the nanotube for the polymer length in the complex formation. Furthermore, the experimental results are compared with a theory based on the Flory-Huggins lattice model. They are in good agreement with each other and the inclusion energy between the molecular nanotube and the linear polymer chain is evaluated.
