摘要

合成了一系列蓝光锆（Ⅳ）配合物 Cl[Zr（NN）（DBM）

]（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）-1

-咪唑-4，5-

-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。

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.
