Selective gas sorption in a [2+3] 'propeller' cage crystal

Selective gas sorption in a [2+3] 'propeller' cage crystal

A [2+3] organic cage compound based on the condensation reaction of 1,3,5-tri(4-formylphenyl)benzene with 1,5-pentanediamine was synthesized. The resulting porous molecular crystal demonstrates selective adsorption of hydrogen and carbon dioxide over nitrogen. As for porous polymer membranes, a trad...

Zusammenfassung:A [2+3] organic cage compound based on the condensation reaction of 1,3,5-tri(4-formylphenyl)benzene with 1,5-pentanediamine was synthesized. The resulting porous molecular crystal demonstrates selective adsorption of hydrogen and carbon dioxide over nitrogen. As for porous polymer membranes, a trade-off between sorption capacity and selectivity is observed for materials in this class.
