Porphyrin based porous organic polymers: novel synthetic strategy and exceptionally high CO2 adsorption capacity.
نویسندگان
چکیده
Iron containing porous organic polymers (Fe-POPs) have been synthesized by a facile one-pot bottom-up approach to porphyrin chemistry by an extended aromatic substitution reaction between pyrrole and aromatic dialdehydes in the presence of small amount of Fe(III). The Fe-POPs possess very high BET surface area, large micropores and showed excellent CO(2) capture (~19 wt%) at 273 K/1 bar.

Porous organic polymers with anchored aldehydes: a new platform for post-synthetic amine functionalization en route for enhanced CO2 adsorption properties.
A novel porous organic polymer has been synthesized using the molecular building block approach to deliberately encompass aldehyde functionalities amenable to post functionalization. The resultant porous framework allows a facile, one-step quantitative and post-synthetic functionalization by amines, permitting enhanced CO2 sorption properties.
متن کاملEnhanced catalytic activity through the tuning of micropore environment and supercritical CO2 processing: Al(porphyrin)-based porous organic polymers for the degradation of a nerve agent simulant.
An Al(porphyrin) functionalized with a large axial ligand was incorporated into a porous organic polymer (POP) using a cobalt-catalyzed acetylene trimerization strategy. Removal of the axial ligand afforded a microporous POP that is catalytically active in the methanolysis of a nerve agent simulant. Supercritical CO2 processing of the POP dramatically increased the pore size and volume, allowin...
متن کاملA triazine-based covalent organic polymer for efficient CO2 adsorption.
A new triazine functionalized hexagonally ordered covalent organic polymer (TRITER-1) has been synthesized via the Schiff-base condensation reaction between a tailor made triamine 1,3,5-tris-(4-aminophenyl)triazine (TAPT) and terephthaldehyde. This ordered porous polymer showed a high BET surface area (716 m(2) g(-1)) and an excellent CO2 uptake capacity of 58.9 wt% at 273 K under 5 bar pressure.

In this study, a novel solid dendrimer amine (hyperbranched polymers) was prepared using mesoporous carbon nitride functionalized by melamine based dendrimer amines. This adsorbent was denoted MDA-MCN-1. The process was stepwise synthesis and hard-templating method using mesoporous silica SBA-15 as a template. Cyanuric chloride and N,N-diisopropylethylamine (DIPEA, Merck) were used for function...
متن کاملSelective CO2 adsorption in a porphyrin polymer with benzimidazole linkages
A new nanoporous porphyrin-based benzimidazole linked polymer, PBILP, was synthesized. The use of porphyrin monomers as molecular building units led to the formation of a rigid amorphous network that has a moderate surface area (SBET 1⁄4 557 m g ). The CO2 adsorption ability of PBILP is 12.1 wt% (2.76 mmol g ) and it has a CO2/CH4 selectivity of 7.2 at 273 K/1 bar and a CO2/N2 selectivity of 72...
