Fluorinated porous organic frameworks for improved CO2 and CH4 capture

A porous 3D selectively fluorinated framework (F-PAF1), robust yet flexible and with a surface area of 2050 m2 g-1, was synthesised by condensation of an ad hoc prepared fluorinated tetraphenylmethane (TPM) monomer to ensure homogenously 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.
Steps to demarcate the effects of chromophore aggregation and planarization in poly(phenyleneethynylene)s. 2. The photophysics of 1,4-diethynyl-2-fluorobenzene in solution and in crystals

Crystals of 1,4-bis(2-hydroxy-2-methyl-3-butynyl)-2-fluorobenzene 4 have a rich packing structure with four distinct molecules in the unit cell. A complex hydrogen bonding network results in the formation of cofacial trimers, cofacial dimers, and monomers

Subject It is to provide a polymerizable compound having a high polymerization reactivity, a high conversion yield and a high solubility in a liquid crystal composition, a polymerizable composition including this compound, a liquid crystal composite prepared from this polymerizable composition and a liquid crystal display device containing this composite. Means for solving the Subject A compound represented by formula (1), the liquid crystal composition and the liquid crystal display device. In the formula, for example, ring A1, ring A2 and ring A4 are phenylene or cyclohexylene; Sp1 and Sp2 are a single bond or alkylene having 1 to 6 carbons; Z1 and Z2 are —CH═CH— or —C≡C—; a is 1, b is 0; and P1 and P2 are a polymerizable group.
