Embodiment 1

[0033] Add 2,3,6,7-tetrabromonaphthaloyl-n-butylimide (694mg, 1mmol) and N-methylimine potassium dithiocarbonate (1098mg, 6mmol) into a 100mL three-neck round bottom flask ; N 2 Under protection, add 50-60mL of anhydrous THF solvent to the above mixture, reflux and stir for 12h, and cool; transfer the cooled reaction mixture to a single-necked round-bottomed flask, and spin the solvent to dry under reduced pressure; Be 20mL mixed solvent that 1 / 5 joins in the reaction mixture that obtains, and at 90 o C stirred and reacted for 24 hours; the reaction mixture was filtered under reduced pressure, and the solid was washed with deionized water until the filtrate was neutral, and then washed three times with ethanol to obtain a purple-red filter cake; the obtained purple-red solid was dissolved in 30-40 mL of Add 2 to 3 g of silica gel to methyl chloride and mix well, spin the solvent under reduced pressure to obtain a purple solid powder; the purple solid powder is separated and p...

Embodiment 2

[0035] According to the method and steps described in Example 1, only 2,3,6,7-tetrabromonaphthalene diamide (750 mg, 1 mmol) was used instead of 2,3,6,7-tetrabromonaphthalene diamide n-Butylimine (694 mg, 1 mmol), 276 mg of orange-red solid powder was obtained, yield 45%. 1 HNMR (400MHz, CDCl 3 )δ(ppm):0.95-1.05(m,6H,-CH 3 ),1.40-1.56(m,12H,-CH 2 -),1.67-1.82(m,4H,-CH 2 -),4.25-4.35(m,2H,-CH 2 -N).

Embodiment 3

[0037] According to the method and steps described in Example 1, except that N-methylimine potassium dithiocarbonate (1464mg, 8mmol) was used instead of N-methylimine potassium dithiocarbonate (1098mg, 6mmol) to obtain an orange-red solid Powder 232mg, yield 42%. 1 HNMR (400MHz, CDCl 3 )δ(ppm):0.96-1.07(m,6H,-CH 3 ),1.41-1.52(m,4H,-CH 2 -),1.68-1.83(m,4H,-CH 2 -),4.23-4.36(m,2H,-CH 2 -N).

Abstract

The invention relates to a bis(1,3-dithiol-2-carbonyl) fused naphthyl imide derivative and a synthesis method thereof, in particular to a method for synthesizing a bis(1,3-dithiol-2-carbonyl) fused naphthyl imide intermediate by performing nucleophilic substitution on halogenated naphthyl imide and carrying out imine hydrolysis under the circumstance that 2,3,6,7-naphthyl imide is taken as a raw material and N-methyl imine dithiocarbonic acid alkali metal salt as a sulfurizing agent. The bis(1,3-dithiol-2-carbonyl) fused naphthyl imide derivative is a kind of an important organic photoelectric material intermediate; according to the synthesis method of the bis(1,3-dithiol-2-carbonyl) fused naphthyl imide derivative, transition metal catalysis, high temperature, water absence, oxygen absence and other severe conditions required for the conventional sulfur atom introduction method are avoided; not only is an intermediate which is simple in structure and easy to derive provided, but also a novel method for conveniently synthesizing bis(1,3-dithiol-2-carbonyl) fused naphthyl imide in a relatively large scale is provided.

Description

technical field [0001] The present invention relates to a kind of bis(1,3-dithio-2-carbonyl) fused naphthalene diimide derivative and its synthesis method, especially in N-methyl imine dithiocarbonate alkali metal salt As a sulfidation reagent, the halogenated naphthalene diimide is subjected to nucleophilic substitution, and the synthesis method of bis(1,3-dithio-2-carbonyl) fused naphthalene diimide intermediate is obtained by imine hydrolysis. Background technique [0002] Organic photoelectric materials containing large aromatic ring conjugated structures have unparalleled advantages over traditional inorganic materials such as diverse structures, low cost, easy processing, light weight, and large-area production. They are widely used in light-emitting diodes, field-effect transistors, thermal batteries, Solar cells and other fields have a wide range of applications. One of the important factors determining the performance of organic optoelectronic devices is the carrie...
