Treatment of AlO(OH) with 3 equiv of 8-hydroxyquinolinol in refluxing deionized water provided the meridional and facial isomers of tris(8-hydroxyquinolinate)aluminum (Alq3) with good yields as solid deposits after 1 and 90 h, respectively. X-ray diffraction and solid-state 13C NMR studies revealed that mer-Alq3 is formed in the early stage of the reaction and then gradually converts to fac-Alq3, which is thermodynamically less stable, although no existence of a catalyst substance is implied.
在回流的去离子水中，用3当量的8 - 羟基喹啉醇处理氢氧化铝（AlO(OH)），分别在1小时和90小时后，以良好的产率得到固体沉淀形式的三（8 - 羟基喹啉酸）铝（Alq3）的经式和面式异构体。X射线衍射和固态13C核磁共振研究表明，经式 - Alq3在反应早期形成，然后逐渐转化为面式 - Alq3，尽管没有暗示存在催化剂物质，但面式 - Alq3在热力学上不太稳定。
