Abstract

The invention discloses an H-Shape cyanidation opto-electric transmission type material and a preparation method and application thereof. Double-spiro fluorenyl is connected with a core (Ar1) by sp<3>carbon, an ''H'' structure is exhibited in space, and the cyanation is performed on fluorenyl two arms to facilitate electron or hole transmission. Due to the introduction of classical electron-withdrawing cyano-based fragments, the transmission material of the type has certain electron/hole transmission properties and can be used as a host material in the field of photovoltaic materials. The preparation method of the H-Shape cyanidation material which exhibits the ''H'' shape in space and has excellent performance is provided, the H-Shape cyanidation material of the type can further regulatethe ability of accepting receptors by regulating the number of cyano groups, molecular energy levels are regulated, good solution-processable opto-electric transmission materials are achieved, good stability in terms of electrochemistry, thermal and spectrum is achieved, and the H-Shape cyanidation opto-electric transmission type material is a kind of material with good application prospects in the field of opto-electric transmission.

Description

technical field [0001] The invention relates to an H-Shape cyanated photoelectric transmission material and its preparation method and application, which can be used in technical fields such as organic electricity storage, organic electricity / photoluminescence, photovoltaic cells, organic nonlinear optics, and organic laser. Background technique [0002] In 1987, Deng Qingyun's research group (Tang, C.W.; Van Slyke, S.A.Appl.Phys.Lett.1987, 51, 913.) published an organic electroluminescent device (Organic Light-emitting Diode, OLED), since then, OLED display has quickly become a new generation of commercial products due to its advantages of self-illumination and low manufacturing cost. The development direction of future display technology is focused on fast speed, ultra-thin, large area and flexibility, and OLED has become the most competitive third-generation display technology. At the same time, research directions including organic solar cells, organic field effect tran...
