摘要
测量了一系列８－羟基喹啉金属螯合物的吸收谱和发射谱。发现当喹啉螯合不同的金属阳离子，其各类光谱有不同程度的红移，本文经验地给出８－羟基喹啉金属螯合物发射谱和吸收谱移动的规律，并分析了金属离子影响光谱的原因。
hydroxyquinoline complexes of Na(Ⅰ),Ca(Ⅱ),Mg(Ⅱ),Zn(Ⅱ),Cu(Ⅱ),Mn(Ⅱ),Al(Ⅲ),In(Ⅲ) and La(Ⅲ) were synthesized.Photoluminescence(PL) and UV Vis absorption spectra characteristics of these complexes and 8 hydroxyquinoline are reported.Except complexes of Cu and Mn,most of these complexes reveal photoluminescence.With the ploarization force of metal cations increasing,the PL peak shows red shift and two broad absorption peak in UV Vis (300—400nm)absorption spectra distinctly appears apart.
