The work described herein describes post-synthesis modification of Nanoporous Organic Frameworks (NPOFs) and its impact on gas storage and selective CO2 capture. The synthesis of NPOF-4 was accomplished via a catalysed cyclotrimerization reaction of 1,3,5,7-tetrakis(4-acetylphenyl)adamantane in Ethanol/Xylenes mixture using SiCl4 as a catalyst. NPOF-4 is microporous and has high surface area (SABET = 1249 m2 g-1). Post-synthesis modification of NPOF-4 by nitration afforded (NPOF-4-NO2) and subsequent reduction resulted in an amine-functionalized framework (NPOF-4-NH2) that exhibits improved gas storage capacities and high CO2/N2 (139) and CO2/CH4 (15) selectivities compared to NPOF-4 under ambient conditions. These results demonstrate the impact of nitro- and amine- pore decoration on the function of porous organic materials in gas storage and separation application.","abstract_html":"Porous organic polymers containing nitrogen-rich building units are among the most promising materials for selective CO2 capture and separation applications that impact the environment and the quality of methane and hydrogen fuels.
