摘要

Two polyoxovanadate-based metal-organic polyhedra with octahedral (oct ) and rhombic dodecahedral (rdo ) geometries have been constructed from a concave molecular building block and linear and triangular carboxylate ligands. VMOP-7 is constructed from {V_(5)O_(9)Cl} SBU and a linear anthracene-9,10-dicarboxylic acid ligand in which all the anthracene groups are perpendicular to the edge of the octahedron. Such an arrangement mode can effectively reduce the steric hindrance between ligands. VMOP-8 is constructed from {V_(5)O_(9)Cl} SBU and a triangular biphenyl 3,4,5-tricarboxylate ligand, which exhibits an elongated rhombic dodecahedral configuration due to the geometry of the ligand. Furthermore, VMOP-8 can serve as a heterogeneous catalyst and exhibits efficient and common catalytic activity for oxidative desulfurization.
