Three porous and robust metalloporphyrin frameworks exhibiting preferable gas storage.

We have achieved success in obtaining three novel two-dimensional porous metalloporphyrin frameworks (MPFs) through solvothermal reactions, by using 5,15-di(4-pyridyl)-10,20-bis(3,4,5-trifluorophenyl) porphyrin ( trans -Py 2 (F 3 -ph) 2 Por) metalated with Fe ( 1 ), Co ( 2 ), and Ni ( 3 ) salts respectively. TGA reveals that they all have high thermal stabilities. Gas adsorption studies indicate that three MPFs have relatively preferable H 2 uptake capacities and the selective adsorption of CO 2 over N 2 . [ABSTRACT FROM AUTHOR]
