| 摘 要： | 以顺丁烯二酰肼(MH)为配体,通过溶剂热法合成了配位聚合物Dy2(MH)6]n·0.5DMF(1)和Eu2(MH)6]n(2)。通过红外光谱、X射线粉末衍射、X射线单晶衍射表征了2个晶体的结构。配合物1和2都是三斜晶系,P1空间群。以双核结构为顶点作图得到配合物的空间拓扑结构,拓扑类型为tsi。配合物的热重分析结果表明2个配合物在315℃左右仍有较好的热稳定性。固体荧光结果表明配合物2在激发波长为375 nm时有对应Eu~(3+)的5D0→7FJ(J=0~4)能级能量的5个发射峰,最强发射峰波长为616 nm,归属为Eu~(3+)的5D0→7F2能级跃迁。

| Abstract: | wo lanthanide-organic frameworksDy2(MH)6]n·0.5DMF (1) andEu2(MH)6]n (2) (MH=maleichydrazide and DMF=N,N-dimethylformamide) have been synthesized and characterized by X-ray single-crystal diffraction and X-ray powder diffraction. Two complexes are both Triclinic P1 space group. Ln(Ⅲ)ions adopt same coordination environments, and seven-coordinated Ln(Ⅲ)atom form feature isostructural 3D structures, topological type:tsi. The luminescence properties of 1 and 2 were investigated. Under the excitation of 375 nm, the emission spectrum of complex 2 shows five peaks at 581, 593, 616, 652 and 705 nm, corresponding to 5D0→7FJ (J=0~4) transitions of Eu3+. The emission spectrum of complex 1 shows a peak at 618 nm, which plausibly arises from π*-π transition of ligands. |
