    • PURPOSE: A novel dendrimer type organic light emitting complex comprising a rare earth metal element is provided to give a light harvesting effect by means of molecular engineering, to improve solubility to a polymer medium, and to prevent coagulation of the rare earth metal element. CONSTITUTION: The dendrimer type organic light emitting complex comprising a rare earth metal element has a structure represented by formula 1, wherein Ln is Er; a is 0, 1 or 2; B is a compound selected from compounds represented by formula 2 or the like. The method for preparing the dendrimer type organic light emitting complex comprises: adding a component selected from KH, B-CO2H, terpyridine or bipyridine into a vacuum dried flask under nitrogen stream; dissolving the mixture with an organic solvent; stirring the mixture till hydrogen gas is not generated therefrom, adding thereto a solution of anhydrous ErCl3 and methanol and stirring it for one day; removing and drying the solvent from the solution in vacuum condition, washing the resulted product with diethylether for several times, and then vacuum drying the resulted compound.
    • 目的:提供一种包含稀土金属元素的新型树枝状大分子型有机发光复合物,以通过分子工程获得光收集效果,以提高对聚合物介质的溶解度,并防止稀土金属元素的凝结。 构成:包含稀土金属元素的树枝状大分子型有机发光复合物具有由式1表示的结构,其中Ln是Er; a是0,1或2; B是选自由式2等表示的化合物的化合物。 制备树枝状大分子型有机发光复合物的方法包括:在氮气流下将选自KH,B-CO 2 H,三联吡啶或联吡啶的组分加入到真空干燥的烧瓶中; 用有机溶剂溶解混合物; 搅拌混合物直到不产生氢气,向其中加入无水ErCl 3和甲醇溶液并搅拌1天; 在真空条件下从溶液中除去和干燥溶剂,用乙醚洗涤得到的产物数次,然后真空干燥所得化合物。
