Patent ID: 8907114

Claim:
A method for preparing a MOF solid of porous and crystallized aluminum aromatic azocarboxylate, comprising: (i) mixing in a nonaqueous organic solvent: at least a metal inorganic precursor in the form of a metal Al, a metal salt Al 3+ or a coordination complex comprising metal ion Al 3+ ; and at least an organic precursor of ligand L, L comprising an aromatic azodi-, azotri-, or azotetra-carboxylate ligand of formula R 0 R 1 N 2 (COO − ) q where R 0 and R 1 independently from each other represent a mono- or poly-cyclic, fused or non fused, aryl radical, comprising 6 to 50 carbon atoms, a mono- or poly-cyclic, fused or non fused, heteroaryl radical comprising 4 to 50 carbon atoms, the R 0 radical being optionally substituted by one or more groups independently selected from the group consisting of C 1-10 alkyl, C 2-10 alkene, C 2-10 alkyne, C 3-10 cycloalkyl, C 1-10 heteroalkyl, C 1-10 haloalkyl, C 6-10 aryl, C 3-20 heterocyclic, C 6-10 aryl C 1-10 alkyl, C 5-10 heteroaryl C 1-10 alkyl, F, Cl, Br, I, —NO 2 , —CN, —CF 3 , —CH 2 CF 3 , —OH, —CH 2 OH, —CH 2 CH 2 OH, —NH 2 , —CH 2 NH 2 , —NHCHO, —COOH, —CONH 2 , —SO 3 H, and —PO 3 H 2 , and q=2 to 4; and (ii) heating the mixture obtained in (i) at a temperature of at least 50° C. so as to obtain said solid.
