  Syntheses, Structures, and Magnetic and Luminescence Properties of a New Dy^III-Based Single-Ion Magnet

  摘要：

  Three new Ln(III) complexes based on 2,2'-bipyridine [Ln(hfac)3(bpy)] (Ln = Dy (1), Tb (2), or Ho (3); hfac = hexafluoroacetylacetonate; and bpy = 2,2'-bipyridine) have been synthesized and characterized structurally and magnetically. Single-crystal X-ray analysis shows that all these complexes contain one [Ln(hfac)3(bpy)] unit in which a center Ln(III) ion is surrounded with a slightly distorted square-antiprismatic LnO(6)N(2) coordination sphere formed. by three bischelate hfac anions and one bpy ligand. Both static and dynamic magnetic properties were studied for complex 1, which is proved to be a new single-ion magnet. The luminescence characterizations of complexes 1 and 2 are also studied in this paper.

  Abstract The coordination chemistry of Ln(hfpd)3 (hfpd=1,1,1,5,5,5-hexafluoropentane-2,4-dionate) with phen and bpy depends on the size of the Ln3+ ion and on the used solvent. The complexes [Er(hfpd)3(phen)] (7) and [Er(hfpd)3(bpy)] (14) were obtained from the synthesis of Er(CF3SO3)3 with Hhfpd, CsOH and either 1,10-phenanthroline or 2,2′-bipyridine in acetonitrile. The structure of 7 was determined

  An in situ solution processed reaction of a bidentate O,O′-chelating anionic hexafluoroacetylacetone (Hhfaa) and a bidentate N,N′-chelating 2,2′-bipyridine ligand with LnCl3·6H2O in the presence of a base afforded the UV-sensitised 400–1800 nm wavelength emitting lanthanide complexes, [Pr(hfaa)3(bpy)2] and [Ln(hfaa)3(bpy)](Ln = Tb, Dy, Tm and Lu). The single-crystal analysis indicates that the Pr complex is ten-coordinate with a distorted bicapped square antiprism while the Dy complex is eight-coordinate with a distorted square antiprism geometry, and the bpy units, in the complexes, are involved in π–π stacking interactions and hydrogen bonding, respectively. The assembly of the hfaa− (a low vibrational frequency ligand) and bpy ligand makes an efficient protective coordination environment (PrO6N4 or DyO6N2) around the Pr (red emission), Tb (green emission), Dy (yellow emission) and Tm (blue emission) ions which leads to high quantum yields and longer emission lifetimes. The quantum efficiency of the complexes is enhanced in the solid state. Furthermore, these volatile and luminescent complexes were used as emitting layers to fabricate red-, green- and yellow-light emitting devices and their electroluminescence performances were investigated. The best devices with the structure ITO/CuPc (20 nm)/[Pr(hfaa)3(bpy)2] or [Tb(hfaa)3(bpy)] or [Dy(hfaa)3(bpy)] (80 nm)/BCP (25 nm)/AlQ (30 nm)/LiF (1 nm)/Al (200 nm) exhibit a maximum brightness of 183, 1765 and 532 cd m−2 with a current efficiency of 0.58, 3.6 and 0.76 cd A−1, respectively, which indicates an improved EL performance over the devices based on Pr, Tb and Dy complexes in the literature.

  一种原位溶液处理反应，将双牙O,O'-螯合的阴离子六氟乙酰乙酮（Hhfaa）与双牙N,N'-螯合的2,2'-联吡啶配体在碱的存在下与LnCl3·6H2O反应，合成了能在400–1800 nm波长范围内发光的紫外线敏化铈系金属复合物[Pr(hfaa)3(bpy)2]和[Ln(hfaa)3(bpy)]（Ln = Tb, Dy, Tm和Lu）。单晶分析表明，Pr复合物为十配位，呈扭曲的双顶方锥体结构，而Dy复合物为八配位，呈扭曲的方锥体几何结构。在这些复合物中，bpy单元分别参与了π–π堆积作用和氢键作用。hfaa−（一种低振动频率配体）与bpy配体的结合为Pr（红色发光）、Tb（绿色发光）、Dy（黄色发光）和Tm（蓝色发光）离子形成了高效的保护配位环境（PrO6N4或DyO6N2），这导致了高的量子产率和更长的发光寿命。在固态中，这些复合物的量子效率得到了增强。此外，这些挥发性和发光复合物被用作发光层，制造红色、绿色和黄色发光器件，并调查了它们的电致发光性能。最佳器件结构为ITO/CuPc（20 nm）/[Pr(hfaa)3(bpy)2]或[Tb(hfaa)3(bpy)]或[Dy(hfaa)3(bpy)]（80 nm）/BCP（25 nm）/AlQ（30 nm）/LiF（1 nm）/Al（200 nm），最大亮度分别为183、1765和532 cd m⁻²，电流效率分别为0.58、3.6和0.76 cd A⁻¹，这表明其电致发光性能优于文献中基于Pr、Tb和Dy复合物的器件。
