Oligophenylenevinylene (OPV) tetracarboxylate luminescent ligand 5 has been synthesized and used for the design of a new Ni(II) layered organic-inorganic compound (8) obtained by the reaction of 5 with nickel(II) nitrate hexahydrate. The hybrid compound 8 has been characterized by powder X-ray diffraction and its magnetic and luminescent properties have been investigated as a function of temperature. The structure consists of the stacking of ferromagnetic Ni(II) based layers at ca. 29 Å apart. A ferromagnetic 3D order occurs at TC = 9.5 K. The study of the temperature dependence of the luminescent properties of the OPV-based hybrid compound shows that the electron sub-system is influenced by the magnetic ordering of the Ni(II) sub-network.
