Abstract
The present invention discloses a polymer containing 1,2,5-benzoselenadiazole-N—R1-5,6-dicarboxylic acid imide, and a preparation method and use thereof. The conjugated polymer prepared by the present invention has fluorescence, and a relatively wide absorption of sunlight, and thus it can be used for manufacture of an active layer for a polymer light-emitting diode device, a polymer field-effect transistor and a polymer solar cell.
