Abstract
The invention discloses a triazole phenothiazine dioxide compound, a photoelectric device and a display device, the triazole phenothiazine dioxide compound has a structure as shown in a formula (I): # imgabs0 #. The triazole phenothiazine dioxide compound disclosed by the invention takes triazole phenothiazine dioxide as a core structure, on one hand, the triazole phenothiazine dioxide has a structure as shown in the formula (I), and on the other hand, the triazole phenothiazine dioxide has a structure as shown in the formula (I); through oxidation of sulfur atoms in phenothiazine, lone pair electrons of the sulfur atoms can be effectively passivated, and the stability of the compound is improved; on the other hand, triazole is introduced into a phenothiazine structure, a formed benzotriazole structure can be used as an ultraviolet absorbent to absorb ultraviolet rays entering a compound and reduce damage of the ultraviolet rays to the compound, and on the other hand, the triazole structure can also effectively adjust the electron density on a molecular skeleton of the whole compound, so that the photoelectric conversion efficiency is improved. Therefore, the photoelectric property of the compound is improved.
