Topological supramolecule such as rotaxane and catenane, which has mechanically interlocked molecular system, is one of the most intensive research areas in chemistry from interests of molecular switch and motor. The University of Tokyo, Advanced Softmaterials Inc. and Nissan Motor Co., Ltd. have cooperatively developed new coating materials with high scratch-resist properties and stretchability based on supramolecular network and slide-ring materials invented by Kohzo Ito and others.
