Jan 19, 2021 · We demonstrate that the CH 4 –CO 2 guest composition impacts the guest–host interactions in hydrates during static temperature measurements at 10 K, implying that these interactions are ...
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.
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.
A host–guest complex is an interesting configuration where the ‘host’ is a molecular configuration that resembles the shape of a ring, with the central cavity playing an essential role of hosting other ‘threads’ of polymer.
Oct 28, 2020 · A relatively small number of guest molecules with a shorter induction time for pure guest hydrate nucleation can promote the formation of initial nuclei of a mixed hydrate. Detailed cage analysis shows that small guests such as CH 4 can induce the formation of more standard cages for mixture systems with either C 2 H 6 or C 3 H 8 systems ...
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.
Besides hydrophobic effect, electrostatic attraction and charge transfer, the host–guest complex is stabilized by the C–H⋯π hydrogen bonding between the included pyridinium ring of the dMV and aromatic walls of CPA5 ( Fig. 2b ); the shortest C⋯π (centroid) distances are 3.21 and 3.16 Å.
