1. A porous material comprising (i) a single pore having a single pore size or (ii) a plurality of pores having an average pore size, wherein the single pore size or the average pore size is proportioned to accommodate a single gas molecule to the exclusion of additional gas molecules;
wherein the single gas molecule is positioned between at least two metal ion dimers in a pore of the material, wherein each dimer comprises an outer metal ion and an inner metal ion, wherein each inner metal ion participates in binding the single gas molecule, and wherein the outer metal ion and the inner metal ion are the same; and wherein (a) each metal ion dimer is bonded by four bis(monodentate) ligands, and at least one of the bis(monodentate) ligands is selected from a compound of formula (I) or (II):wherein A1 is selected from the group consisting of naphthalenyl, quinolinyl, naphthyridinyl, anthracenyl, and acridinyl;wherein A2 is selected from the group consisting of phenyl, pyridinyl, naphthalenyl, naphthyridinyl, and acridinyl, andX1 is selected from the group consisting of ethynyl,or
(b) each metal ion dimer is bonded by four tetra(monodentate) ligands, and at least one of the tetra(monodentate) ligands is selected from a compound of formula (V) or (VI):wherein A4 is selected from the group consisting of pyridinyl, naphthalenyl, quinolinyl, naphthpyridinyl, anthracenyl, and acridinyl;wherein A5 is selected from the group consisting of phenyl, pyridinyl, naphthalenyl, naphthpyridinyl, and acridinyl, andX2 is selected from the group consisting of ethynyl, |
