Treatment of the sodium complexes with europium(III) chloride gave the corresponding EuIII cryptates. The structural and spectral properties of these compounds are described. The EuIII complexes present characteristic 1H-NMR chemical-shift features. Their luminescence properties are described.
大双环配体1-6的钠盐盐酸盐已通过直接大双环化或逐步方法合成。它们并入了2,2′-联噻唑,2,2′-联咪唑,2.2′-联嘧啶以及2,2′-联吡啶单元。用氯化euro(III)处理钠络合物得到相应的Eu III隐窝。描述了这些化合物的结构和光谱性质。Eu III配合物具有特征性的1 H-NMR化学位移特征。描述了它们的发光特性。
