以8-羟基喹啉和乙酸铜为主要原料,通过简单调控醇水介质和熟化时间,液相沉淀法快速合成出大量不同形貌和晶型的8-羟基喹啉铜微纳米材料.采用SEM,XRD,UV-Vis,FT-IR对产物进行表征.结果表明,以8-羟基喹啉盐酸水溶液与乙酸铜水溶液反应,合成了直径40～130nm的棒状α型二水合8-羟基喹啉铜沉淀物.以8-羟基喹啉乙醇溶液与乙酸铜乙醇溶液反应,获得了厚度约300nm的三维(3D)板条束状α型无水8-羟基喹啉铜微纳米结构.若采用8-羟基喹啉乙醇溶液与乙酸铜的乙醇/水溶液反应,当体系醇/水体积比为3∶1时,随着熟化时间的延长,产物由亚稳的α型和γ型晶相向稳定的β型晶相转变,形貌从胡须束状/菱片状混合结构转变为纳米棒状/菱片状混合结构,50min熟化后最终形成菱片状β型二水合8-羟基喹啉铜及其四角星形自组装体.
A series of 8-hydroxyquinoline copper micro-nano materials with different morphologies and crystal forms were rapidly synthesized by simply adjusting the alcoholic medium, aging time and liquid-phase precipitation with 8-hydroxyquinoline and copper acetate as raw materials. , XRD, UV-Vis and FT-IR.The results showed that 8-hydroxyquinoline dihydrate with the diameter of 40-130 nm was synthesized by the reaction of 8-hydroxyquinoline hydrochloride with copper acetate aqueous solution Precipitated with 8-quinolinol ethanol solution and copper acetate ethanol solution to obtain a thickness of about 300nm three-dimensional (3D) ribbon α-type anhydrous 8-hydroxyquinoline copper micro-nano structure.Using 8- When the system alcohol / water volume ratio was 3:1, the product was composed of metastable α-type and γ-type phase to stable β-type The crystal phase transitions from bearded bundle / rhombic mixed structure to nanorod / rhombic mixed structure. After 50min ripening, the rhombohedral copper (Ⅱ) -quinoxaline dihydrate and its four-pointed star Self-assembly.
