| abstract | The invention belongs to the technical field of OLED and provides a polymer having a structure represented by formula (I), wherein R 1 and R 2 are respectively selected from C1-C20 alkyl, C3-C20 cycloalkyl, C1-C20 alkoxy base, substituted or unsubstituted aryl or heteroaryl; L is selected from single bond, phenyl, naphthyl, pyridyl, pyrimidinyl, pyrazinyl; R is selected from substituted or unsubstituted aryl and heteroaryl group; R 4 is selected from C4-C20 alkyl or alkoxy; n≥4. The polymer of the present invention contains a diborocarbazole structure and has TADF properties. When it is used in an organic light-emitting device, the triplet excitons that are forbidden by traditional fluorescent molecular transitions can be used to emit light, thereby improving the device efficiency. At the same time, the carbazole polymer-based TADF material itself has bipolar characteristics. As the host or guest material of the light-emitting layer, it can greatly improve the transport capacity of two carriers and improve the carrier balance, improve the fluorescence quantum efficiency and reduce the device. Voltage. |
