Host–guest chemistry - Wikipedia
In supramolecular chemistry, [1] host–guest chemistry describes complexes that are composed of two or more molecules or ions that are held together in unique structural relationships by forces other than those of full covalent bonds. Host–guest chemistry encompasses the idea of molecular recognition and interactions through non-covalent ...
6.5.1: Host-Guest Chemistry and π-π Stacking Interactions
In host-guest chemistry, a large molecule or network host uses noncovalent interactions to bind a smaller molecule guest in a binding pocket. Schematically this interaction is often represented as:
Host-Guest Complex - an overview | ScienceDirect Topics
Host–guest complexes can be seen to arise from the coordination of a cationic, anionic, or neutral guest entity within a discrete host molecule or supramolecular host assembly, using noncovalent interactions, such as H-bonds, ionic bonds, van der Waals forces, and hydrophobic interactions.
Host-Guest Chemistry - an overview | ScienceDirect Topics
The host-guest chemistry is a proven technique to encapsulate and stabilize different guest species inside the cavity of the nanocarriers with the aid of physical or chemical interactions. 11 Interestingly, this can alter the solubility of the guest molecules, and at the same time make the targeted delivery of the guest species possible.
Supramolecular Chemistry: Host–Guest Molecular Complexes
The physisorbed nanoporous supramolecular complexes have been widely used to restrain various guest species on compact supporting surfaces. The host–guest (HG) interactions in two-dimensional (2D) permeable porous linkages are growing expeditiously due to their future applications in biocatalysis, separation technology, or nanoscale patterning.

2023年10月2日 · In this Review, we summarize recent progress in macrocycle-based solid-state host–guest chemistry and discuss the basic physical chemistry of these complexes. Representative macrocycles and...
Host-Guest Interaction - an overview | ScienceDirect Topics
Host-guest interaction refers to a non-covalent interaction between two molecules, where one molecule acts as the host and the other as the guest. The host molecule has a cavity or cleft that allows the guest molecule to fit in, forming a complex. This interaction is reversible, allowing the guest molecule to dissociate from the host molecule.
The Design of Molecular Hosts, Guests, and Their Complexes | Science …
The origins, definitions, tools, and guiding principles of host-guest chemistry are developed. Perching, nesting, and capsular complexes are exemplified through molecular model and crystal structure comparisons. The degree of preorganization of a host for binding is a central determinant of its binding power.
Host–Guest Complexes - PMC
Host–guest complexes, also known as inclusion complexes, are supramolecular structures [1,2] composed of two or more molecules or ions that are maintained through noncovalent interactions in a reversible way .
In 1974 with Jane M. Cram, we published a general article entitled “Host-Guest Chemistry”, which defined our approach to this research [12]. Aeschylus, the Athenian Poet-Dramatist, wrote 2 500 years ago, “Pleasantist of all ties is the tie of host and guest” [13].
