Abstract

The invention discloses a cyclopentadiene-bridging dimeric perylene diimide compound and a preparation method thereof. The preparation method comprises the following specific steps: firstly, 1-nitro-3,4:9,10-perylentetracarboxylic diimide, cyclopentadiene and inorganic alkali salt are mixed and dissolved in a polar aprotic organic solvent and react for 0.5-3 hours to obtain a mixed solution; and then 2 mol / L diluted hydrochloric acid is added into the obtained mixed solution dropwise, a precipitate is precipitated and subjected to suction filtration, a coarse product is obtained after the precipitate is washed with water and subjected to silica-gel column chromatography to obtain a product, and the leaching liquid volume ratio of dichloromethane to ethyl acetate is 20: 1. The preparation method is simple in step, the product is obtained through one-step reaction, the cost is low, the reaction time is short, and the reaction conditions are mild.

Description

technical field

[0001] The invention belongs to the technical field of organic synthesis, and in particular relates to a cyclopentadiene-bridged bisperylene diimide compound and a preparation method thereof. Background technique

[0002] Perylene derivatives are a class of compounds with special structures, which have excellent thermal stability, light stability, chemical stability and excellent dyeing performance. Since Kardo discovered perylene tetracarboxylic diimide compounds in 1913, these compounds have been widely used in the dye industry and coating industry. With the development, research and wide application of optoelectronic materials, perylene compounds have attracted more and more attention due to their excellent optoelectronic properties. Among them, dimerized and polymerized perylene diimide compounds, due to their better optical and electrical properties, have broad application prospects and are increasingly valued by researchers. However, the general react...
