A fluorene copolymer, method for preparation thereof, and use thereof are provided. Said fluorene copolymer comprises copolymer represented by formula (I), wherein R1-R2, R5-R8 are selected from H or C1-C20 alkyl, R3-R4 are selected from H, C1-C20 alkyl, C1-C20 alkoxyl, phenyl or phenoxyl, x+y=1, x≠0, y≠0; n is an integer of 1 to 200, Ar1 is thiophene unit-containing group. On account of thiophene unit and thienopyrazine unit, the fluorene copolymer has wide spectrum response range and favorable stability.
提供了一种萘共聚物及其制备方法和用途。所述萘共聚物包括由式(I)表示的共聚物,其中R1-R2、R5-R8选择自H或C1-C20烷基,R3-R4选择自H、C1-C20烷基、C1-C20烷氧基、苯基或苯氧基,x+y=1,x≠0,y≠0;n为1至200的整数,Ar1为含噻吩单元的基团。由于噻吩单元和噻吩吡嗪单元,该萘共聚物具有宽波谱响应范围和良好的稳定性。
