Abstract

Five 8-hydroxyquinoline complexes of tin were prepared by reacting diphenyltin dichloride with 8-hydroxyquinoline and its derivatives for using as fluorescent materials in organic light-emitting diodes (OLEDs). The elemental analysis and IR, UV–vis, 1H and 119Sn NMR spectroscopes were used to characterize the prepared compounds. The details and features of the reaction were described and discussed. The prepared compounds were utilized as the green-yellow EL dopant materials to fabricate OLED devices with a general configuration of ITO/PEDOT:PSS(90 nm)/PVK:PBD:tin-complex(80 nm)/Al(200 nm). PVK (polyvinyl carbazole) and PBD (2-(4-Biphenylyl)-5-phenyl-1,3,4-oxadiazole) as hole-transporting and electron-transporting materials, respectively, were doped within tin compounds as the emissive layer. The results of the investigation of electroluminescent (EL) and photoluminescence (PL) properties of prepared complex showed that the electron donating or withdrawing substituent groups on 8-hydroxyquinoline have a significant effect on the tuning and changing of emission wavelengths.
