Paragraph 0026-0028, (2017/08/25)
The invention relates to a near infrared fluorescence-emission organic nano-wire and a preparation method thereof. The organic nano-wire comprises 2, 4, 6-TBTP. The preparation method comprises that p-hydroxybenzoic acid and urotropine undergo a backflow reaction in trifluoroacetic acid at a temperature of 105-115 DEG C, the reaction product is cooled to a room temperature, the cooled reaction product is poured into water, the solution is filtered, the filtered product and 2-aminothiophenol undergo a backflow reaction in dimethylsulfoxide at a temperature of 175-185 DEG C, the reaction product is cooled to a room temperature, the cooled reaction product is poured into water, the solution is filtered and purified to form 2, 4, 6-TBTP, the 2, 4, 6-TBTP is dissolved in chloroform, and the solution is natural and completely volatilized in a fuming cupboard at a room temperature. The preparation method has simple processes. The near infrared fluorescence-emission organic nano-wire has solid fluorescence emission wavelength of 500-750nm in a near infrared zone, a Stokes shift of 200nm or more, a high fluorescence emission quantum yield and an important application prospect in development of an organic near infrared luminescent material.
