Extended and functionalized porous iron(III) tri- or dicarboxylates with MIL-100/101 topologies

A series of nanometric isoreticular and/or functionalized analogues of the mesoporous environmentally-friendly iron(III) polycarboxy-lates MIL-100/101 have been successfully synthesized. Their exceptional pore size, of up to 68 angstrom, together with their relatively good stability in solvents, makes them promising candidates for heterogeneous catalysis or inclusion of large molecules, among others.
