Abstract

The invention discloses the reduction-state ionic salt of perylene bisimide and a derivative thereof as well as a preparation method. The preparation method comprises the following steps: with perylene-3,4,9,10-tetracarboxylic acid dianhydride as a raw material, synthesizing a perylene bisimide derivative with low LUMO energy level and excellent photoelectric performance through a bromination reaction, an amidation reaction and a nucleophilic substitution reaction; and synthesizing the perylene bisimide monovalent ionic salt with stable environment relatively easily according to the benzoquinone type transformation mechanism in an alkaline condition (organic base such as triethylamine, and inorganic base such as potassium carbonate). The method for synthesizing the perylene bisimide ionic salt is novel, unique and simple and realizes high yield; industrialization can be implemented while the effect is good; and moreover, the material in a reduction state responds to metal ions and acids different in oxidability.

Description

technical field [0001] The invention relates to an organic compound and a synthesis method thereof. Background technique: [0002] Perylene imide and its derivatives have good photothermal stability, light absorption characteristics and high fluorescence quantum yield. Perylene imide and its derivatives are widely used in optical materials such as organic solar cells and field effect transistors. [0003] However, the preparation and application of ionic salts of peryleneimide and its derivatives are relatively few, or even blank. According to the latest report, the preparation process of the ionic salt of perylene imide is limited to the reduction with sodium thiosulfate, electrochemical reduction and C / Pd-H 2 reduction. Moreover, these preparation processes have strict requirements on raw materials and synthesis conditions, the cost is high, and they are not suitable for industrialization. Invention content: [0004] The object of the present invention is to provide ...
