Syntheses,Crystal Structures and Luminescence Properties of Nd Complexes with β-Diketonate and Triphenylphosphine Oxide
【摘要】 在温和条件下合成了2种以β-二酮和三苯氧膦为配体的钕三元配合物[Nd（TTA）3（TPPO）2]（1）（TTA=2-噻吩甲酰三氟丙酮,TPPO=三苯氧膦）和[Nd（BFA）3（TPPO）2]（2）（BFA=4,4,4-三氟-1-苯基-1,3丁二酮）,获得了单晶并通过X射线单晶衍射确定了配合物结构。晶体分析显示,2种配合物均为八配位结构,属于三斜晶系,P1空间群。采用元素分析、红外光谱和热重分析对2种配合物进行了结构表征;通过近红外荧光分析,探讨了配合物的荧光特征。
【Abstract】 Two ternary complexes of neodymium ions, [Nd（TTA）3（TPPO）2]（1） and [Nd（BFA）3（TPPO）2]（2）, based on4,4,4-trifluoro-1-（2-thienyl）-1,3-butanedione（TTA）, 4,4,4-trifluoro-1-phenyl-1,3-butanedione（BFA） and triphenylphosphineoxide（TPPO） have been synthesized by mild condition and the single crystals suitable for X-ray measurement were obtained. The structures of the two Nd complexes were determined in solid states by X-ray diffraction. Single crystal analysis revealed that the complexes are both eight-coordinated with one center Nd ion and eight O atoms from ligands and crystallize in triclinic symmetry with P1 space group. The complexes were characterized by elemental analysis, IR spectroscopy and thermogravimetric. Furthermore, photophysical studies on the complexes were carried out, which shows luminescence in near-infrared area.
