| 摘 要： | A new cyclometalated platinum complex containing 2, 5-bis（naphthalene-1-yl）-1,3,4-oxadiazole ligand was synthesized and characterized. The UV-Vis absorptions and photoluminescent properties of the ligand and its platinum complex were investigated A characteristic metal-ligand charge transfer absorption peak at 439 nm in the UV spectrum and a strong emission peak at 625 nm in the photoluminescence spectrum were observed for this complex in dichloromethane. Cyclic voltammtry （CV） analysis shows that the EHOMO （energy level of the highest occupied molecular orbital） and ELUMO （energy level of the lowest unoccupied molecular orbital） of the platinum complex are about -5.69 and -3.25 eV, respectively, indicating that the oxadiazole-based platinum complex has a potential application in electrophosphorescent devices used as a red-emitting material.

| Abstract: | A new cyclometalated platinum complex containing 2, 5-bis(naphthalene-1-yl)-1,3,4-oxadiazole ligand was synthesized and characterized.
The UV-Vis absorptions and photoluminescent properties of the ligand and its platinum complex were investigated. A characteristic
metal-ligand charge transfer absorption peak at 439 nm in the UV spectrum and a strong emission peak at 625 nm in the photoluminescence
spectrum were observed for this complex in dichloromethane. Cyclic voltammtry (CV) analysis shows that the E
HOMO (energy level of the highest occupied molecular orbital) and E
HOMO (energy level of the lowest unoccupied molecular orbital) of the platinum complex are about −5.69 and −3.25 eV, respectively,
indicating that the oxadiazole-based platinum complex has a potential application in electrophosphorescent devices used as
a red-emitting material.
