Our vision is that this web collection will provide a showcase of current achievements while providing a springboard for future success in the field of host-guest chemistry. This collection, Guest Edited by Feihe Huang (Zhejiang University), Jonathan L. Sessler (The University of Texas at Austin), and Tomoki Ogoshi (Kyoto University), will cover not only host-guest complexes based on crown ethers, cyclodextrins, calixarenes, cucurbiturils, calixpyrroles, pillararenes, and other macrocyclic hosts, but also more complex supramolecular systems such as molecular switches, molecular machines, supramolecular polymers, supramolecular macromolecules and gels, macrocyclic amphiphiles, supra-amphiphiles, supra-monomers, supramolecular radicals, nonporous adaptive crystals, and other supramolecular materials based on host-guest chemistry. The collection will provide a spectrum of contributions that run the gamut from fundamental science all the way to real world applications involving areas as diverse as gene/drug delivery, smart/adaptive materials, devices, adsorption phenomena, separations, supramolecular chemotherapy, supramolecular cancer nanotheranostics, supramolecular analytical chemistry, information storage, coding and anti-counterfeitting, as well as supramolecular medicinal chemistry, to name a few of the many opportunities that are currently being perused. This collection intends to set a standard of excellence that will inspire current practitioners while attracting new researchers into the field.
