摘要

合成了一系列蓝光锆(Ⅳ)配合物[Zr(NN)(DBM)3]Cl(DBM=二苯甲酰基甲烷, NN=1,10-邻菲罗啉 1; 2, 9-二甲基-1,10-邻菲罗啉 2; 4,4′-二甲基-2,2′-联吡啶 3; 1-乙基-2-(1-萘基)-1H-咪唑-4,5-f-1,10-邻菲罗啉 4), 以波长为355 nm的紫外光激发, 4个配合物的最大发射峰均位于445 nm左右, 半峰宽只有36~45 nm。在相同的测试条件下, 配合物1的蓝光发射强度最大, 量子效率最高, 其原因是结构刚性强, 能够有效地减少非辐射跃迁造成的能量损失。而且, 配合物1~3的热稳定性很好, 分解温度均在200 ℃以上, 可以用于制作有机发光器件, 不会在器件的制作过程中发生分解。

Abstract

A series of blue-emission Zr(Ⅳ) complexes [Zr(NN)(DBM)3]Cl(DBM=dibenzoylmethane,NN=1,10-phenanthroline 1; 2,9-dimethyl-1,10-phenanthroline 2; 4,4′-dimethyl-2,2′-bipyridine 3; 1-ethyl-2-(naphthalen-1-yl) -1H-imidazo-4,5-f-1,10-phenanthroline 4) were synthesized. The emission peaks of these complexes are all centered at 445 nm upon excitation at 355 nm, while their half-width are in the range of 36~45 nm. Under the same condition, complex 1 shows the strongest emission and highest photoluminescence quantum yield. This result attributes to its rigid structure because such structure can efficiently decrease energy loss coming from non-radiative transition. Moreover, the decomposing temperatures of complexes 1-3 are all above 200 ℃ indicating their excellent thermal stability. Such results suggest that complexes 1-3 can be utilized in the preparation of light-emitting device.
