With a scalable synthesis of C 18 and OPP develop in future, OPP and its derivatives are expected to be used as storage materials for C 18 ring with controllable lowtemperature enrichment and high-temperature release, and the applications of supramolecular material containing 2C 18 @OPP as a nanoengine in electronic area is promising. Given the great success of C 18 and OPP in synthesis, and the excellent performance of these two molecules in intermolecular interactions, it is believed that the systems considered in this work are not elusive predictions, but supramolecular complexes that are very likely to be realized. We hope that experimental scientists can realize this idea in the near future.
