Abstract

The invention relates to a reduction state of perylene bisimide and a derivative of the perylene bisimide and a preparation method. Perylene-3,4,9,10-tetracarboxylic acid dianhydride is adopted as a raw material, and the perylene bisimide derivative with the low LUMO energy level and excellent photoelectric property is obtained through a bromination reaction, an amidation reaction and a nucleophilic substitution reaction in a synthesis manner; and then under the condition of the normal temperature, a first reduction potential is applied through an electrochemical method to easily obtain an air stable perylene bisimide radical anion through synthesis. The method for preparing perylene bisimide ionic salt is novel, unique, simple and high in yield and can achieve industrialization, and the effect is good; and materials of this kind have high stability on air in the reduction state, the science difficult problems are solved, and practical application is facilitated.
