Oct 5, 2016 · The characteristics of host–guest systems, such as molecular recognition, complexation, encapsulation, guest composition, and dynamic exchange, are manifested by changes in the chemical shifts (Δω) in the NMR spectrum.
Aug 7, 2018 · Radial distribution functions and three-dimensional density distributions provide insight into the changes in guest orientation and interactions with the host framework as a function of guest composition.

Aug 12, 2021 · The study thus gave a novel example of a host–guest mixture that is able to carry out composition-driven structural modulation and guest-induced nanotemplates. The finding broadens the horizon of host–guest chemistry and may inspire more nanoinnovation.

Aug 3, 2021 · In supramolecular host–guest complexes, the guest molecules are encapsulated either partially or entirely into the cavities of the macrocyclic cavitand or host molecules. Thus, the compatibility in the size and shape of the host cavity and the guest molecule is essential in the formation of the host–guest complex.

Considering these aspects, we recently began investigating their solid-state supramolecular chemistry and reported the first structural authentication of carboxylic acid substituted pillararene (CPA5), its basic self-assembly properties and formation of a host–guest complex with active pharmaceutical ingredient tetracaine.8 Our current work is focu...
While the shape of the CPA5 macrocyclic core resembles a regular pentagon, the closer look reveals some deviation from regular Euclidean geometry. For a regular pentagon, the interior angles are 108°, while the sp3 hybridization of the bridging methylene groups in pillararene would favor the bonding angle of 109.28°. The structural strain within th...
