本研究では、抽出剤であるN,N,N',N'-Tetrakis(2-pyridylmethyl)ethylenediamine(TPEN)に加え、エチレン鎖上にメチル基を導入した誘導体N,N,N',N'-Tetrakis(2-pyridylmethyl)-1,2-propanediamine(MeTPEN)を配位子として用いて、希土類元素であるユウロピウム(Eu)の錯体を合成し、それらの分子構造や各種物性を様々な分光分析を駆使して比較した。

In this presentation, N,N,N',N'-Tetrakis(2-pyridylmethyl)ethylenediamine(TPEN) and the derivative, N,N,N',N'-Tetrakis(2-pyridylmethyl)-1,2-propanediamine(MeTPEN) which methylene chain was substituted by methyl group were used as ligand to synthesize europium complexes and which molecular structures and properties were compared by using spectroscopic methods.
