Synthesis and gas transport properties of new aromatic 3F polymers

Preparation of Ni-MOF-74 membrane for CO2 separation by layer-by-layer seeding technique

“…It is shown that the permeance of the support increases with transmembrane pressure drop. For the macroporous support, the increasing trend in permeance indicates that the gas transport through the support includes both Knudsen diffusion and viscous flow [39]. The permeance of hydrogen through different membranes (S-1, S-4, S-8 and the sample by in situ method) is also given at different transmembrane pressure drop in Fig.…”

Crystal packing analysis of in situ cryocrystallized 2,2,2-trifluoroacetophenone

“…Research work in recent years has shown that TFAP can be used as a green organocatalyst in synthetic procedures, e.g. for the epoxidation of alkenes (Limnios & Kokotos, 2014a), the oxidation of allyloximes to form isoxazoline (Triandafillidi & Kokotos, 2017), the oxidation of aliphatic tertiary amines and azines (Limnios & Kokotos, 2014b) and for the synthesis of substituted tetra-hydrofurans (Theodorou & Kokotos, 2017a), indolines and pyrrolidines (Theodorou & Kokotos, 2017b), besides being used for the synthesis of fluorinated polymers (Guzmá n-Gutié rrez et al, 2008). Interestingly, TFAP has been also used for probing intermolecular interactions involved in the bi-molecular complexes formed on Pt(111) surfaces (Goubert et al, 2011).…”

Investigation of the Molecular Structures, Electronic Properties and Vibrational Spectrum of Trifluoroacetophenone Using Density Functional Theory

“…11 It has been found that incorporation of fluorine atoms into macromolecules even with a slight difference leads to polymers with enhanced chemical resistance, thermal stability, glass transition temperature and solubility. 8 Similarly, the catalytic efficiency of epoxidation reactions using fluoroalkyl ketones is found to be affected by introducing a slight difference in molecular structures of this class of compounds. 4,12 The trifluoromethyl (CF 3 ) moiety is also reported to have played a crucial role in the modification and enhancement of the biological activities of trifluoromethylated organic compounds.…”

“…1,2 TFAP is regarded as an efficient, inexpensive, environmentally friendly, mild, fast, and sustainable organocatalyst for the oxidation of alkenes to corresponding epoxides, 3,4 the oxidation of azines and tertiary amines to corresponding nitrogen oxides, 5,6 enantionselective hydrogenation, 6,7 and aldol reactions. 8 It is also used for the synthesis of thermally stable fluorinated polymers that have good film-forming properties. 8 The study of the molecular structure and spectral properties of TFAP has attracted attention in recent years due to its catalytic and biological activities.…”

“…8 It is also used for the synthesis of thermally stable fluorinated polymers that have good film-forming properties. 8 The study of the molecular structure and spectral properties of TFAP has attracted attention in recent years due to its catalytic and biological activities. The surface vibrational spectroscopy of TFAP adsorbed on the surface of platinum was reported using high resolution energy loss spectroscopy.…”
