报道了金属有机配合物二苯基锡双羟基喹啉(Sph2q2)的合成及其电致发光性质。该络合物由二苯基二氯化锡与8-羟基喹啉反应而成，其吸收截止波长为460 nm，最大发光波长为508 nm。用光电子能谱测得Sph2q2的电离电势为∼6.0 eV，电子亲和势为3.3 eV。Sph2q2被用作双层器件的发射层和电子注入层。对Sph2q2的电致发光特性和电荷注入特性进行了表征。Sph2q2易溶于常见有机溶剂，进一步修饰其性质是可能的。结果表明，四价锡配合物是一种潜在的电致发光和电荷注入材料。
We report the synthesis and electroluminescent properties of the organometallic complex diphenyltin bis-hydroxyquinoline (Sph2q2). The complex was prepared by the reaction of diphenyltin dichloride with 8-hydroxyquinoline and shows an absorption cutoff wavelength of 460 nm and bright photoluminescence with a peak wavelength at 508 nm. The ionization potential of Sph2q2 was determined to be ∼6.0 eV by photoemission apparatus, and the electron affinity is estimated to be 3.3 eV. Sph2q2 was used as an emitting and electron injection layer in bilayer devices. The electroluminescence (EL) properties and charge injection properties of Sph2q2 are characterized. Sph2q2 is easily soluble in common organic solvents and further modification of its properties is possible. The results indicate that tetravalent tin complexes are potential emitting and charge injection materials for EL applications.
