摘　　要：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 zinc complex with a novel schiff base, ZnL, was synthesized and characterized by elemental analyses, FT-IR, UV-vis absorption, fluorescence spectra, DTA-TG and cyclic vohammetry, in which the ligand compound is N, N＇-bis （ 2-hydroxy-l-naphthylidene ） -3,6-dioxa-1,8-diaminooctane （H2L）. The blue fluorescence with peak at 455 nm of the complex either in solution or in solid films was observed under excitation by 385 nm. The electroluminescent （EL） devices with the ZnL complex as the emitting layer were fabricated and they exhibit bright blue EL emission and the maximum brightness is 650 cd · m^-2, the external quantum efficiency is about 0.63 cd/A at a bias voltage of 9.5 V.
