摘　　要：在无水乙醚中制备了二(2,4-二甲基-8-羟基喹啉)(苯酚)铝[Al(DMQ)2Ph],二(2,4-二甲基-8-羟基喹啉)(对戊基苯酚)铝[Al(DMQ)2PenPh]两个络合物,通过红外光谱、紫外光谱、元素分析等进行了结构表征。在室温下通过荧光光谱测得其薄膜状态下最大发光峰位为501nm和491nm,分别较Alq3蓝移29nm和39nm,同时通过热重分析研究了络合物的热稳定性。The solid complexes bis（2,4-bimethyl-8-quinolinolinato）（phenolato）aluminum[Al（DMQ）2Ph] and bis（2,4-bimethyl-8-quinolinolinato）（4-amyl-phenolato）aluminum were prepared in absolute ether system,and confirmed by IR,UV and element analysis. The maximum wavelengths of the film fluorescent spectra for two complexes are 501 nm,491 nm at room temperature. The [Al（DMQ）2Ph] and [Al（DMQ）2PenPh] showed 29 nm,39 nm blue shift in comparison with Alq3 separately. The decomposition processes were investigated by TG-DTG.
