Abstract

The invention relates to a novel method for synthesizing a novel organic OLED reagent easily and conveniently. According to the compound, DCE is adopted as a solvent, 0.1mol% TsOH is adopted as a catalyst, triazole, olefin and water react for 48 h at the temperature of 80 DEG C, and the target compound is obtained through concentration and column chromatography. The method is simple in reaction, high in yield, free of metal and environmentally friendly. The product has a high quantum yield as a new organic OLED. In the formula I (see the formula in the description), R1 and R2 can be aryl groups, hydrogen and the like, and R3, R4, R5 and R6 can be alkyl groups, aryl groups, hydrogen and the like.

Description

technical field [0001] The invention relates to a new method for conveniently synthesizing a novel organic OLED reagent. Background technique [0002] OLED backlight is a reflective two-dimensional surface light source with high brightness, wide color gamut, stamping resistance, low voltage, thinness and low power consumption. Its cathode metal layer is a specular reflection layer with high reflectivity, so OLED The backlight does not need light guiding and uniform light accessories such as a light guide plate and a diffuser plate, and can directly reflect the light emitted by the light emitting layer to the LCD, which meets the requirements of the LCD for the backlight, so OLED has the opportunity to become The protagonist of the LCD backlight in the new era. [0003] Here, we invented the first method for preparing a new type of organic OLED by reacting olefins with triazoles. Using DCE as a solvent and 0.1 mol% TsOH as a catalyst, triazoles, olefins and water were reacte...
