The supramolecular network formation through inclusion complexation between α ‐cyclodextrin‐based molecular tube (MT) and poly(ethylene oxide) monocetylether‐ graft ‐dextran (5C 16 PEO‐ g ‐Dex40) was demonstrated. From isothermal titration calorimetric (ITC) measurement, it was confirmed that MT formed an inclusion complex with two C 16 PEO side chains in 5C 16 PEO‐ g ‐Dex40. From viscosity measurements, the specific viscosity of the solution containing MT and 5C 16 PEO‐ g ‐Dex40 was much larger than that containing 5C 16 PEO‐ g ‐Dex40. It is considered that MT participates in the supramolecular network formation of 5C 16 PEO‐ g ‐Dex40 through inclusion complexation with two C 16 PEOs grafted to independent Dex40s.
