[摘要]:Pillar substitution in a long-known metal-organic material with saturated metal centres, [Cu(bipy)(2)(SiF6)](n), has afforded the first crystallographically characterized porous materials based upon TiF62- and SnF62- anions as pillars. Gas adsorption studies revealed similar surface areas and adsorption isotherms but enhanced selectivity towards CO2 vs. CH4 and N-2. |
