中文摘要：
通过分子设计，合成了一种新颖的双β-二酮配体N-正丁基-3，6-二（1，3-丁二酮基）咔唑（H2L）及其铕配合物。单晶X衍射测定了H2L的晶体结构。配体和配合物的红外光谱和电子光谱表明，Eu^3＋与H2L发生螯合配位。配体的荧光光谱是宽带的蓝色发光，属H2L→H2L跃迁，而配合物的溶液荧光光谱除了配体的蓝光带外，还有611nm处的Eu^3＋的特征红光，属^5D0→^7F2跃迁带；配合物的光致发光光谱只有613nm处为Eu^3＋的特征红光，属^5D0→^7F2跃迁带，峰形尖锐，单色性好，表明该配合物为一种潜在的红色发光材料。
英文摘要：
By molecular designing, a new bis （β-diketonate） ligand 3,6-bis （ 1,3-butyldiktone）-9-n-buthylcarbazole （H2L） and its Eu^3＋ complex were synthesized and characterized by single crystal X-ray diffraction, IR and Uv-vis spectra. In the photo-luminescence spectrum of liquid complex, the 611nm emission was attributed to ^5D0→^7F2 of Eu^3＋ ion and thewide blue band could be assigned to H2L→H2L. The photoluminescence of solid complex indicated that there is only a sharp and strong red peak at 613 nm, which was attributed to 5D0→^7TF2 of Eu^3＋ ion. The resuits showed that this Eu^3＋ complex would be a promising red light material.
