Synthesis Of Organic - Inorganic Coordination Polymers Based On 1,3,4-oxadiazole Bridging Organic Ligands And Rigid Conjugated Fulvene Ligands And Nature Of The Study

The chemistry of organic-inorganic coordination polymers has recently become area of increasing interest. Self-assembly of organic ligands and inorganic metal ions is one of the most efficient and widely used approaches for the construction of organic-inorganic composite materials. In this paper, we wish to report the syntheses, structures and luminescent properties of 22 new organic-inorganic coordination polymers generated from 1, 3, 4-oxadiazoie-containing ligands or fulvene ligands. A. The coordination chemistry of 1, 3, 4-oxadiazole-containing ligandsThe coordination chemistry of the oxadiazole-containing ligandsB. Synthesis of fulvene ligands and their coordination chemistryOne new Ag(I)-fulvene polymeric compounds, namely were synthesized based on ligands L16.C. The luminescent properties of organic ligands LI, L2 ,L3, L4 and also selected polymeric compounds were investigated in solid state and solvent. The results have shown that the emission wavelength and intensity of free organic molecules were affected by their incorporation into the metal -containing polymeric compounds.D. Some foundamental study in light emitting material of organic polymers.The results reported herein demonstrate that the use of 1,3,4-oxadiazole-containing or fulvene-type organic spacers as precursors to bind transition metal ions, is in fact a new approach for the formation of novel supramolecular networks with interesting physical properties.
