Guest replacement in a flexible single-crystal host by mixing the surrounding gas.

چکیده
The adsorption behavior of a single-crystal host [Cu2(bza)4(pyz)]n under vapor was studied by adsorption measurements and single-crystal X-ray analyses, demonstrating the sharp replacement of the included guest by mixing the surrounding vapor.

Magmatic Interaction as Recorded in Texture and Composition of Plagioclase Phenocrysts from the Sirjan Area, Urumieh-Dokhtar Magmatic Arc, Iran
Tertiary andesitic basalts of the Sirjan area, Urmieh-Dokhtar Magmatic Arc, Iran, contain plagioclase phenocrysts enclosed in a matrix of amphibole, clinopyroxene and rare olivine crystals. Textural and compositional evidence suggests two significantly different types of plagioclase phenocrysts occur in the andesitic basalts. The most common type of plagioclase phenocrysts have zoning patterns ...
متن کاملTransformable Single-Crystal Adsorbent Based on 1-D Coordination Polymer Skeletons
Recently, we found a single crystal host, [M(II)2(bza)4(pyz)]n (bza and pyz = benzoate and pyrazine, M = Rh and Cu), which is suitable for the study of gas-containing structure through gas adsorption. They generated gas inclusion crystals by transition from a closed to an open phase through the process of smooth physisorption; guest gases are adsorbed into the generated narrow channels of the l...
متن کاملHydrogen and halogen bonding drive the orthogonal self-assembly of an organic framework possessing 2D channels.
Orthogonal self-assembly of an open organic framework showing 2D channels has been obtained by combining hydrogen and halogen bonding. The framework is able to host various guest molecules with a diverse set of steric demands and substitution patterns, and survives single-crystal-to-single-crystal guest exchanges from liquid and gas phases.
متن کاملSupramolecular-jack-like guest in ultramicroporous crystal for exceptional thermal expansion behaviour
The dynamic behaviours of host frameworks and guest molecules have received much attention for their great relevance with smart materials, but little has been developed to control or understand the host-guest interplay. Here we show that the confined guest can utilize not only molecular static effects but also bulk dynamic properties to control the host dynamics. By virtue of the three-dimensio...
متن کاملExperimental and molecular dynamics studies of anthraquinone dyes in a nematic liquid-crystal host: a rationale for observed alignment trends.
Five anthraquinone dyes with bis(4-propylphenyl) substituents, connected via sulfide or amine linking groups at the 1,5-positions or directly at the 2,6-positions, have been studied as guests in the nematic liquid crystal host, E7. Polarized UV-visible absorption spectra of aligned samples were used to obtain experimental dichroic order parameters, which exhibit values in the range 0.51-0.74. F...
