Method for improving black phosphorus through azobenzene derivatives and obtained compound thereof

The invention discloses a method for improving black phosphorus through azobenzene derivatives. The method includes the steps that the black phosphorus and the azobenzene derivatives are added into anorganic solvent to obtain a mixed solution; and under the condition of 0-20 DEG C, the mixed solution is subjected to water bath ultrasound, the ultrasonic time is 6-8 hours, alternate illumination of ultraviolet light and visible light is given in the ultrasonic process, the alternation time is 5-30min, the ultrasound is finished and then standing is carried out, a supernatant is taken for centrifugal separation, and a compound of the azobenzene derivatives and black phosphorus nanosheets is obtained by collecting deposits. According to the obtained compound of the azobenzene derivatives andsolution dispersible black phosphorus, wide application prospects in the fields of solar thermal fuel, photothermal therapy and the like are achieved. 本发明公开了种利用偶氮苯衍生物对黑磷进行改进的方法，将黑磷与偶氮苯衍生物加入到有机溶剂中，得到混合溶液；在0～20℃条件下，对上述混合溶液水浴超声，
