Abstract


Organic - inorganic ligand supramolecular polymer chemistry based on the self-assembly strategy is one of the international chemical industry is the most active, the most cutting-edge research areas, and is also the synthesis of new organic - inorganic composite functional materials, one of the most effective way. This paper reports a series of rigid conjugated nanoscale fulvene ligands, cyclopentadienyl and pyridazine triazine structure of the new fulvene ligands, benzo pyrazine ligand end group of Schiff-base organic complexing body and The transition metal ion coordination reaction chemistry. 22 new fulvene and Schiff-base organic ligands and 12 new organic - inorganic coordination polymers synthesized by X-ray single crystal diffraction, IR, elemental analysis and thermal gravimetric analysis to characterize the structure; addition still represented by the solid-state fluorescence emission guest molecule adsorption - desorption and conductive nature. Containing cyclopenta pyridazine triazine structure novel fulvene ligand with the reaction chemistry of the metal ion by the functionalization reaction of hydrazine hydrate, phenyl hydrazine, and the fulvene ligand obtained containing cyclopenta pyridazine triazine structure fulvene ligand L6-L10. This class of ligand and metal silver salt was synthesized three based on the fulvene ligand-metal organic coordination polymer [Ag (L6) (] ClO4) · 1.5 (C6H6 () 1), [Ag (L6)] SbF6 (2), [Ag (L10)] (ClO4) · (C6H6) (3). Second, the Schiff-base polydentate organic ligand with the reaction chemistry of the metal ion studied systematically symmetric Schiff-base polydentate organic ligand (L11) and (L12) with an inorganic silver salt ligand assembly chemistry. L11, L12 AgClO4 · H2O, AgPF6, AgSbF6, AgBF4 and AgNO3 reaction, get the novel structure of the coordination polymers of Ag3 (L11) 3 (BF4) 3 (CH2Cl2) 3 (H2O) (4), Ag2.5 (L11) 1.5 (ClO4) 2.5 (H2O) 2 (5), Ag4 (L11) 3 (PF6) 4 (6), Ag4 (L11) 3 (SbF6) 4 (7), Ag3 (L12) 2 (SbF6) ? 0.5H2O (8), Ag3 (L12) 2 (ClO4)? 0.5H2O (9), [Ag3 (L12) 2 (PF6) 3]? H2O (10), and [Ag (L12) NO3]? CH3OH (11 The); asymmetrical double Schiff-base ligand the L19 and AgSbF6 reaction has been a novel supramolecular structure [Ag (C31H26N10)] SbF6 (12). Third, apart from elemental analysis and IR, 1H NMR and thermal gravimetric analysis to characterize the structure of the above polymer, yet their single crystal structure was determined by X-ray diffraction method. In addition, the solid state fluorescence of the part of the representative compounds emission, the adsorption - desorption and the conductive properties of the guest molecules were studied. The above two types of organic supramolecular and organic - inorganic composite materials chemistry - inorganic coordination polymers not only adds new content; provide a new approach to finding and screening new organic - inorganic composite.
