Description

technical field [0001] The present invention relates to a dibenzodrysme derivative, specifically a dibenzodrysme derivative that can be used for interface modification, and also relates to the application of the dibenzodryste derivative. Background technique [0002] Organic solar cells (OPVs) and organic electroluminescent devices (OLEDs) are two of the most important types of organic optoelectronic devices, which have the advantages of low fabrication cost, flexibility, biocompatibility, large-area fabrication, and solution processability. The main working mechanisms of OPV and OLED are opposite, but both devices usually have a similar layered structure, such as an organic layer sandwiched between an anode and a cathode. In OPV devices, the electrodes play the role of collecting charges. In OLED devices, carriers are injected from the electrodes. The interface between the electrodes and the organic layer is the key factor to achieve high performance of the device. [0003...
