Embodiment 1

[0040] (1) Preparation of five-membered sulfur heterocyclic perylene tetracarboxylate n-butyl ester in bay position:

[0041] Add 40 mg (1.25 mmol) of sulfur powder and 8 ml of N-methylpyrrolidone (NMP) into a 25 ml round bottom flask, and stir at 90° C. for 10 minutes. Under argon protection, 50 mg (0.073 mmol) of n-butyl mononitrated perylene tetracarboxylate was added, reacted at 110°C for 6 hours, and followed the reaction by thin-layer chromatography. After the reaction, the reaction solution was poured into 100 ml of water to precipitate a precipitate, left to stand, and filtered under reduced pressure, the filter cake was washed 2 to 3 times with 10% ethanol aqueous solution, and the collected solid was vacuum-dried to obtain a crude product. The crude product was subjected to silica gel column chromatography, and the eluent was dichloromethane:ethyl acetate=20:1. Obtained 35 mg (0.051 mmol, about 70% yield) of intermediate product.

Abstract

The present invention discloses a preparation method of bay-bit embedded pentabasic sulfur heterocycle and hexahydric oxygen heterocycle 3,4:9,10-perylene n-butyl tetracarboxylate. The method comprises the steps of: dissolving bay-bit mononitration-3,4:9,10-perylene n-butyl tetracarboxylate in N-methylpyrrolidone, reacting with elemental sulfur to obtain an intermediate product bay-bit embedded pentabasic sulfur heterocycle-3,4:9,10-perylene n-butyl tetracarboxylate; further nitrating the intermediate product to obtain the bay-bit mononitration single sulfur ring perylene n-butyl tetracarboxylate; and reacting the bay-bit mononitration single sulfur ring perylene n-butyl tetracarboxylate with an acid-binding agent and a nucleophilic reagent capable of forming carbanion to obtain the desired product bay-bit embedded pentabasic sulfur heterocycle and hexahydric oxygen heterocycle 3,4:9,10-perylene n-butyl tetracarboxylate. The bay-bit embedded pentabasic sulfur heterocycle and hexahydric oxygen heterocycle 3,4:9,10-perylene n-butyl tetracarboxylate prepared by the invention employs different annulations at two sides of the bay-bit, substantially enlarges the molecular conjugated system, enhances molecular flatness, and can select different substituents to change intramolecular charge distribution, so as to tune electronic structure and photophysical property of the molecule.

Description

technical field [0001] The invention belongs to the field of organic synthesis, and in particular relates to a preparation method of n-butyl perylene tetracarboxylate embedding five-membered sulfur heterocycles and six-membered oxygen heterocycles in the bay position. Background technique [0002] Perylene tetracarboxylic acid n-butyl ester derivatives are widely used in organic field effects due to their good electron-accepting ability, high fluorescence quantum yield, high photothermal stability, unique photoelectric properties and redox properties. Transistors, photochromic materials, light-absorbing arrays, organic solar cells, light-emitting diodes, and liquid crystal color filters are recognized as a class of organic dyes with extremely high utilization value. Therefore, it is particularly important to derivatize n-butyl perylene tetracarboxylates. Among them, the ring expansion reaction can increase the conjugated π system of perylene derivatives, thereby effectively ...
