摘　　要：本文考察了各种氟代三(8-羟基喹啉)铝(Alq3)衍生物的热稳定性,比较了真空蒸镀薄膜和固体粉末的形貌和结晶性,并研究了其聚集态性质。研究结果表明,氟取代使热分解温度有所下降,在薄膜状态下各种氟代Alq3衍生物呈无定型状态,而在粉末状态下则呈现多晶结构。Thermal stability of several kinds of fluorinated aluminum tris-（8-hydroxyquinoline） （Alq3） derivatives was investigated. The morphology and crystallinity of these Alq3 derivatives in vacuum-deposited film and solid powder were compared, and their aggregation properties were studied. The results show that the decompostion temperatures of Alq3 derivatives descended by fluorination. All fluorinated Alq3 derivatives were amorphous in films, but polymorphous in powders.
