The invention relates to copolymer complexes of the formula (I):
wherein [A
x
-[B(C)]
y
-D
z
] denotes a single unit of the copolymer complex that is repeated n times, wherein n is an integer greater than one, and wherein the single unit comprises a conjugated backbone coordinated to a complex (C) comprising rare earth metal(s); x, y and z are numbers greater than zero such that x=y+z; A is independently selected from a group consisting of: fluorene, carbazole, oxadiazole, triphenylamine or derivatives thereof; B is a functional ligand selected from the group consisting of: benzoic acid, 1,3-diphenylpropane-1,3-dione, 1,10-phenanthroline, 2,2-bipyridine, or derivatives thereof; and D is independently selected from a group consisting of: fluorene, carbazole, oxadiazole, triphenylamine or derivatives thereof.
该发明涉及公式(I)的共聚物复合物:
其中[Ax-[B(C)]y-Dz]表示重复n次的共聚物复合物的单个单位,其中n是大于1的整数,且单个单位包括与包含稀土金属的复合物(C)配位的共轭骨架;x、y和z是大于零的数字,使得x=y+z;A独立地选自以下组:萘、咔唑、噁二唑、三苯胺或其衍生物;B是从苯甲酸、1,3-二苯基丙烷-1,3-二酮、1,10-邻菲啰啉、2,2'-联吡啶或其衍生物组中选择的功能性配体;D独立地选自以下组:萘、咔唑、噁二唑、三苯胺或其衍生物。
