合成了吡嗪 [2 ,3 f]并邻菲罗啉及其一系列衍生物 ,作为第二配体 ,并以二苯甲酰甲烷为第一配体 ,合成了 3种新的铕 (III)三元配合物 .通过元素分析、红外光谱、核磁共振光谱确定了它们的组成 ,研究了三种配合物的热稳定性、成膜性能和光致发光性能 (发光强度、荧光量子效率和寿命 ) ,并初步从理论上探讨含有不同基团的第二配体的结构对铕 (III)配合物发光的影响 ,结果表明 :这三种铕 (III)三元配合物均为优良的红色发光材料 ,而且在真空条件下均形成均衡的薄膜 ,这为以这三种铕 (III)配合物作为发光层材料制作有机电致发光器件提供了认识基础
Synthesis of pyrazine [2, 3 f] and 1,10-phenanthroline and a series of derivatives, as the second ligand, and dibenzoylmethane as the first ligand, the synthesis of three new europium (III ) Ternary complexes were synthesized and characterized by elemental analysis, IR and NMR spectra. Their thermal stability, film-forming properties and photoluminescence properties (luminescence intensity, fluorescence quantum efficiency and lifetime) The effects of the structure of the second ligand containing different groups on the luminescence of europium (III) complexes were studied theoretically. The results show that the three europium (III) ternary complexes are excellent red luminescent materials , And the formation of a uniform thin film under vacuum conditions provides a basis for understanding the fabrication of organic electroluminescent devices using the three europium (III) complexes as the light-emitting layer material
