The annulation reaction was dependent on the nature of the substituent at the β-position of the vinamidinium species.展开更多

Then the substrate was reacted with ruthenium and 6-bromo-2,2′-bipyridine to form a new Schiff base type Ru complexes. The process of the complexes assembled was characterized by UV-Vis absorption spectra and XPS. The film exhibited photoluminescence arising from π *-t_ 2g ligand-to-metal transition of Ru complex. From the fluorescent spectra, we observed the behavior of Ru(Ⅱ) complexes is greatly affected by the schiff base ligand. The novel Schiff base ligand Ru(Ⅱ) complexes exhibited strong and pure luminescent intensity. It was different from the other type ruthenium complexes. The result shows that there are many ralations between the structure and the properties of the complex.展开更多
