Inclusion compounds
WebTo form conventional urea inclusion compounds, guest molecules act as a template, while hydrogen-bonded urea molecules are arranged along the guests76. Urea molecules adopt a helical rotation, either right-handed or left-handed77, along the hexagonal tunnels. In urea inclusion compounds, the guest molecules are densely packed within and along ...

Inclusion Compound: A complex in which one component (the host) forms a cavity or, in the case of a crystal, a crystal lattice containing spaces in the shape of long tunnels or channels in which molecular entities of a second chemical species (the guest) are located. See more In host–guest chemistry, an inclusion compound (also known as an inclusion complex) is a chemical complex in which one chemical compound (the "host") has a cavity into which a "guest" compound can be accommodated. … See more Calixarenes Calixarenes and related formaldehyde-arene condensates are one class of hosts that form inclusion compounds. One famous illustration is the adduct with cyclobutadiene, which otherwise is unstable. See more Cryptands and crown ethers typically do not form inclusion complexes since the guest is bound by forces stronger than van der Waals bonding. If the guest is enclosed on all … See more
