芳香铵及其氮氧化物稀土配合物因具有一定的荧光性质而得到广泛的研究,但文献中以2—羧基喹啉氮氧化物(简写为 HAN—O)为配体的金属离子配合物至今未见报道。本文报道了具有荧光特性的镧系高氯酸盐与 HAN—O 的固态配合物的合成,并对其某些物理化学性质进行了测定和讨论。2—羧基喹啉氮氧化物的合成 将2—羧基喹啉在冰醋酸介质中用30%过氧化氢氧化,氧化产物经无水乙醇重结晶即得淡黄色的2—羧基喹啉氮氧化物的针状晶体。
Aromatic ammonium and its nitrogen oxides rare earth complexes have been widely studied for their fluorescence properties. However, metal ion complexes with 2-carboxyquinoline oxynitride (HAN-O) No reports. In this paper, the synthesis of solid complexes of lanthanide perchlorate with HAN-O with fluorescence properties has been reported. Some of its physico-chemical properties have been measured and discussed. Synthesis of 2-carboxyquinoline nitroxide 2-carboxyquinoline was oxidized with 30% hydrogen peroxide in glacial acetic acid medium and the oxidation product was recrystallized from absolute ethanol to give pale yellow 2-carboxyquinoline oxynitride Needle crystal.
