Invention relates to a single step preparation of alkali metal quinolate of general formula 1
wherein
M=Lithium, sodium or potassium;
R═H, alkyl (C1-C6), alkoxy, aryl, aryloxy, amino, amido or halogen (Cl, F, Br, I) which is substituted or unsubstituted with direct reaction of metal with 8-hydroxyquinoline. Substituted 8-hydroxyquinoline optionally have at least one substituent selected from the group consisting of alkyl, alkoxy, aryl, aryloxy, amino, amido at 2, 5 or 7 position. Halogen substituted 8-hydroxyquinolates are also prepared from this method in the yield of 90-95% from polar solvents like acetonitrile. These complexes are useful as light emitting and electron injecting materials in organic electronic devices. Also the doping of these materials in electron transport materials improves their electron mobility.
本发明涉及一种碱
金属
喹啉酮的单步制备方法,其一般
化学式为1,其中M为
锂、
钠或
钾;R为H、烷基(C1-C6)、烷氧基、芳基、芳氧基、
氨基、酰胺基或卤素(Cl、F、Br、I),可以是取代或未取代的,直接将
金属与
8-羟基喹啉反应。取代的
8-羟基喹啉可选择在2、5或7位至少有一种取代基,包括烷基、烷氧基、芳基、芳氧基、
氨基、酰胺基等。卤素取代的
8-羟基喹啉酮也可以从这种方法中制备,产率为90-95%,使用极性溶剂如
乙腈。这些配合物可用作有机电子器件中的发光和电子注入材料。此外,将这些材料掺杂到电子传输材料中可以提高它们的电子迁移率。
