Comotti, A.; Castiglioni, F.; Bracco, S.; Perego, J.; Pedrini, A.; Negroni, M.; Sozzani, P. published the artcile< Fluorinated porous organic frameworks for improved CO2 and CH4 capture>, SDS of cas: 76-84-6, the main research area is fluoropolymer polyacetylene synthesis adsorbent carbon dioxide methane adsorption.
A porous 3D selectively fluorinated framework (F-PAF1), robust yet flexible and with a surface area of 2050 M2 g-1, was synthesized by condensation of an ad hoc prepared fluorinated tetraphenylmethane (TPM) monomer to ensure homogeneously distributed C-F dipoles in the swellable architecture. Tetradentate TPM was also the comonomer for the reaction with fluorinated difunctional monomers to obtain frameworks (FMFs) with a controlled amount of regularly spaced reorientable C-F dipoles. The isosteric heat of adsorption of CO2 was increased by 53% by even moderate C-F dipole insertion, with respect to the non-fluorinated frameworks. CO2/N2 selectivity was also increased up to a value of 50 for the difluoro-containing comonomer. Moreover, methane shows optimal interaction energies of 24 kJ mol-1.
