合成了一种含萘酚基的开链冠醚Sch iff碱-锌配合物ZnL(其中配体化合物H2L是N,N′-双(2-羟基-1-萘亚甲基)-3,6-二氧杂-1,8-三甘醇二胺)。通过元素分析、红外光谱、差热-热重分析、紫外吸收光谱、荧光光谱和循环伏安法对其结构和性质进行了表征,并成功地制备了基于该材料的电致发光器件。结果表明,ZnL配合物的溶液或固体薄膜在385 nm紫外光激发下发光峰为455 nm,电致发光器件的最大亮度达到650 cd/m2,在电压为9.5 V左右,最大效率达到0.63 cd/A。
A naphthol group-containing open-chain crown ether Sch iff base-zinc complex ZnL (wherein the ligand compound H2L is N, N’-bis (2-hydroxy-1-naphthalenemethylene) -3,6 Dioxa-1,8-triethylene glycol diamine). Its structure and properties were characterized by elemental analysis, infrared spectroscopy, DTA-TG, UV absorption spectroscopy, fluorescence spectroscopy and cyclic voltammetry. The electroluminescent devices based on this material were successfully fabricated. The results showed that the luminescence peak of ZnL complex solution or solid film excited at 385 nm was 455 nm, the maximum brightness of electroluminescent device was 650 cd / m2, and the maximum efficiency was 0.63 cd / A.
