WebNov 1, 2024 · The host–guest chemistry is usually a small guest molecule encapsulated in a larger host molecule via noncovalent interactions. And the common host molecules include cucurbiturils (CB) and cyclodextrins (CD) [ 41 ]. In addition, CD–participated polymer with well–defined structure, high reactive sites and flexible functionality [ 42 ]. WebHost–guest supramolecular chemistry is classified by the formation of a noncovalent complex of a guest molecule in the portal of a macrocyclic cavitand. Applications of this …
