Inclusion compounds
WebThe inclusion concept in crystal chemistry arises because there exist a large number of crystal classes in which one can clearly identify a host structure that contains guest atoms, ions, or molecules. In these, geometric and topological effects are of very great importance, and the concept of inclusion is useful not only in determining whether ... WebSingle crystals of inclusion compounds between urea or thiourea and carotenoids have been grown from solution, using 2-propanol as solvent. Figure 41 shows the structures of the dialkylpolyenes from which inclusion compounds have been obtained.

IUPAC definition. 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 … 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. … See more WebSep 7, 2024 · Complexation of aroma compounds using starch inclusion complex could be a potential approach due to the hydrophobicity of the left-handed single helical structure.
