使用不同的氧化劑來使4-脂基胺苯胺或羥基芳香族胺與8羥-基喹啉(8HQ)反應，會得到不同收率的亞胺喹啉醌化合物(IQLO)。由氧化劑、苯胺類化合物和8HQ的氧化還原電位，推知以過硫酸氨同時氧化4-脂基胺萃胺與8HQ反應得到較高收率的IQLO。合成得到的IQLO化合物與金屬離子螫合可得到九種錯化合物，其最大吸收波長在581-757 nm之間。以元素分析確認其組成外，由其UV和IR吸收特性也可推論金屬離子螫合於配位化合物的亞胺喹醌部份之氧原子和吡啶部份的氮原子。

The iminoquinolinone-type ligands (IQLO) were synthesized by condensing 4-alkylaminopenylamines or hydroxy aromatic amines with 8-hydroquinoline (8HQ) in the presence of an oxidizing agent. The yield of IQLO was different from the reactants and experimental results, the reaction of 4-alkylaminophenylarnines with 8HQ was proposed to proceed by oxidation of aromatic hydroxyamines with oxygen and gave IQLO in 83-98% yields. The metal complexes containing IQLO were synthesized , in addition, these complexes exhibited absorption bands at 581757 nm. Also, EA, UV and IR were used to characterize these complexes. Coordination occurs via the oxygen atom of the quinoneimine moiety and the nitrogen atom of the pyridine moiety, as suggested by the above results.
