“…Higher uptakes are found for DF8 with 73.28 cm 3 /g (3.26 mmol/g) of CO 2 adsorbed at a pressure around 1 bar while for DF2 the amount of CO 2 adsorbed is assessed at 57.40 cm 3 /g (2.55 mmol/g) around 1 bar. These values are comparable 23−25 or higher 3,12,22 with respect to CO 2 uptakes recorded for other hyper-cross-linked polymers (see also Table S1). If a ratio between the SSA BET and the amount of CO 2 adsorbed by the material is obtained it is seen that DF materials, particularly DF2, show a ratio lower with respect to many reported HCPs (see Table S1).…”

“…Hyper-cross-linked polymers (HCPs) are porous organic materials easily obtained via the Friedel–Crafts alkylation reaction which leads to stable and amorphous polymeric networks incorporating both micro- and mesoporosities. HCPs have been employed for numerous applications like gas adsorption, , pollutants removal, separation, and energy storage, , as additives for polymer-based mixed matrix membranes (MMMs) for gas separations applications, , and for catalysis and sensing . Unfortunately, the lack of regioselectivity associated with Friedel–Crafts alkylation does not allow one to control the resulting 3D structure, limiting the possibility to customize the polymeric framework for specific applications.…”

An optimized Friedel -Crafts based methodology to prepare high surface area and pore volume hypercrosslinked polymers (HCPs) is here presented. A significant reduction in catalyst quantities resulted in an HCP showing SSABET of 905 m 2 /g and total pore volume of ≈ 1.12 cc/g. Spectroscopic investigations (DR-FTIR and SS-NMR) reveal that lowering the amount of catalyst avoid uncontrolled reaction pathways. For the optimized material CO2 uptakes are 2.55 mmol/g at 273 K and 1 bar. High pressure measurements at 298 K resulted in the uptake of 7.33 mmol/g of CO2 at 24 bar and 3.84 mmol/g of CH4 at 42 bar.

“…A probable explanation for these drops is that the pores were partially blocked by the produced phosphonium-based ILs. 40 Fig. 4b shows that the pore-size distribution of PPh 2 PStD-PCoVPP-1 was mainly in the range of 3.8 nm to 32.36 nm.…”

Ruthenium nanoparticles stabilised by an amine‐modified Ordered Mesoporous Silica Immobilized Ionic Liquid (OMSIIL) are efficient catalysts for the partial reduction of nitrobenzene to hydrazobenzene with 100% selectivity as well as the complete reduction to aniline. High selectivity for the partial reduction of nitrobenzene to hydrazobenzene was obtained when the reaction was conducted in ethanol with 0.5 mol% catalyst and NaBH4 as the hydrogen donor whereas aniline was obtained as the sole product in water when dimethylamine borane (DMAB) was used as the hydrogen donor. Interestingly, while a range of electron poor nitroarenes were reduced to the corresponding hydrazoarene with high selectivities and good conversions, nitroarenes substituted with electron donating groups resulted in complete reduction to the aniline. Composition‐time profiles suggest that reductions conducted in ethanol with sodium borohydride occur via the condensation pathway while those conducted in water using dimethylamine borane as the hydrogen source may well go via the direct pathway. This is the first example of the selective reduction of nitrobenzene to hydrazobenzene using a ruthenium nanoparticle‐based catalyst and the initial TOF of 320 mol nitrobenzene converted mol Ru‐1 h‐1 is markedly higher than previous literature reports.
