A theoretical survey on strength and characteristics of F•••F, Br•••O and Br•••Br interactions in solid phase
A quantum chemical investigation was carried out to study the properties of intermolecular F•••F, Br•••Br and Br•••O interactions in crystalline 1-bromo-2,3,5,6-tetrafluoro-nitrobenzene (BFNB). This system was selected to mimic the halogen-halogen as well as halogen bonding interactions found within crystal structures as well as within biological systems. We found that fluorine atoms have weak ...
متن کاملEnhancement of CO2 Affinity in a Polymer of Intrinsic Microporosity by Amine Modification
Nitrile groups in the polymer of intrinsic microporosity PIM-1 were reduced to primary amines using borane complexes. In adsorption experiments, the novel amine-PIM-1 showed higher CO2 uptake and higher CO2/N2 sorption selectivity than the parent polymer, with very evident dual-mode sorption behavior. In gas permeation with six light gases, the individual contributions of solubility and diffusi...
متن کاملMixed Matrix Membranes of Boron Icosahedron and Polymers of Intrinsic Microporosity (PIM-1) for Gas Separation
This work reports on the preparation and gas transport performance of mixed matrix membranes (MMMs) based on the polymer of intrinsic microporosity (PIM-1) and potassium dodecahydrododecaborate (K₂B12H12) as inorganic particles (IPs). The effect of IP loading on the gas separation performance of these MMMs was investigated by varying the IP content (2.5, 5, 10 and 20 wt %) in a PIM-1 polymer ma...
متن کاملSimulated swelling during low-temperature N2 adsorption in polymers of intrinsic microporosity.
Polymers of intrinsic microporosity (PIMs) are a promising alternative in gas separation applications; however, their industrial applicability is greatly reduced by their susceptibility toward sorption-induced plasticization. In this study, the effects of swelling during nitrogen adsorption isotherms at 77 K for five PIMs (PIM-1, PIM-1c, PIM-SBF, PIM-SBF-Me, and sPIM-1) were examined through pr...
متن کاملA computational chemistry investigation of the intermolecular interaction between ozone and isothiocyanic acid (HNCS)
The binding energy and geometrical structure of all the possible dimeric systems of isothiocyanic acid (HNCS) with ozone have been investigated in the gas phase, theoretically. Six minima located on the singlet potential energy surface of the HNCS–ozone system at the MP2 level with binding energies (corrected with ZPE and BSSE) in the range 492.29–531.40 kcal/mol. All intermolecular interaction...
