Synthesis And Luminescent Property Of Cu/Ir/Re Complexes

In order to gain new organic optical functional materials, phosphorescene iridium complexes with1,2,4-triazole derivatives as the first ligands and actylacetone(acac) as ancillary ligands have been successfully synthesized, and Cu(Ⅰ) and Re(Ⅰ)complexes with1-[(2’,3’,4’,5’-tetraphenylbiphenyl-4-yl)methyl]-2-(pyridin-2-yl)-1H-benzo[d]imidazole have been successfully synthesized.]HNMR, IR, UV/Vis absorption and luminescent of the above complexes have been studied to gain their structure and property. The ground state geometry and their uv-vis absorption spectra of the Cu(Ⅰ) complexes, Re(Ⅰ) complexes and benzylsulfonyl functionalized phenylpyridine iridium(Ⅲ) complexes were also theoretically studied. All the synthesized iridium(Ⅲ) complexes give rise to resemble absorptions, but differ in the max emission wavelength. Cu(Ⅰ) and Re(Ⅰ) complexes also have aggregation-induced emission property.
