Abstract

The structural properties of Co-doped tris(8-hydroxyquinoline)aluminum (Alq(3)) have been studied by grazing incidence X-ray absorption fine structure (GIXAFS) and Fourier transform infrared spectroscopy (FTIR). GIXAFS analysis suggests that there are multivalent Co-Alq(3) complexes and the doped Co atoms tend to locate at the attraction center with respect to N and O atoms and bond with them. The FTIR spectra indicate that the Co atoms interact with the meridional (mer) isomer of Alq(3) rather than forming inorganic compounds.

摘要

通过掠入射 X 射线吸收精细结构（GIXAFS）和傅里叶变换红外光谱（FTIR）研究了 Co 掺杂三（8-羟基喹啉）铝（Alq（3））的结构特性。GIXAFS 分析表明，存在多价 Co-Alq（3）配合物，掺杂的 Co 原子倾向于位于相对于 N 和 O 原子的吸引中心，并与之键合。FTIR 光谱表明，Co 原子与 Alq（3）的子午（mer）异构体相互作用，而不是形成无机化合物。
