[0017] The preparation method of the compound described in the present invention is described further below: (1) 2-(4,5-di-n-hexylthio-1,3-dithio-2-ylidene)-5-hydroxymethylene-5 - Preparation of hydrogen-6-dihydro-1,3-dithio[4,5-b][1,4]dithiocyclohexane:

[0018] After Zincate is dissolved in acetone, add hexyl bromide dissolved in acetone dropwise in boiling state, wherein the molar ratio of Zincate and hexyl bromide is 1:5.3, continue to reflux for 2-4 hours, and remove insoluble matter by suction filtration. The solvent was distilled off, and the residue was purified by column chromatography to obtain 4,5-di-n-hexylthio-1,3-dithiol-2-thione, one of the raw materials required for the coupling reaction. The reaction formula is as follows: Show:

[0019] After reflux for 20 hours in the same way, another raw material 5,6-dihydro-5-acetoxymethylene-1,3-dithio[4,5-b][1,4] was purified to obtain the coupling reaction Dithiocyclohexane-2-thione.

[0026] Example 4, 5-di-n-hexylthio-1,3-dithiole-2-thione

[0027] 8g Zincate (11.2mmol) was dissolved in 100mL acetone, heated to reflux with stirring, 50mL acetone solution containing 9.4mL (60mmol) bromohexane was added dropwise, and refluxed for 4 hours. Suction filtration to remove insoluble matter. Acetone was removed by rotary evaporation. The residue was subjected to column chromatography (chloroform:petroleum ether=1:2 as the developing solvent) and the developing solvent was rotated to obtain 8 g of orange-red oil with a yield of 98%. MS(EI): m / z(%)=367(M + +1, 14.119), 366 (M + , 27.196) 5,6-dihydro-5-acetoxymethylene-1,3-dithio[4,5-b][1,4]dithiocyclohexane-2-thione

[0028] Add 7.2g (10mmol) Zincate and 100mL acetone into a 250mL three-neck flask. 11.4 mL (80 mmol) 2,3-dibromopropyl acetate / 50 mL acetone were added dropwise under stirring and reflux, and the reaction was carried out for about 20 hours. TLC tracking, the developing solvent...

Abstract

The present invention discloses the structure and preparing process of a molecular assembly of metal phthalocyamine and substituted dithioethylene tetrathiofulvalene. The said molecular assembly is amacro-molecular compound with intramolecule charge transfer, and can be used in molecule switch field.

Description

technical field [0001] The invention relates to a compound with intramolecular charge transfer and a preparation method thereof. Background technique [0002] Tetrathiafulvalene (TTF) and its derivatives are good π-electron donors (Donor), which can generate stable cationic radicals. This free radical can generate conductive intermolecular charge transfer complexes with numerous electron acceptors, for example, the CT-complex of tetrathiofulvalene and tetracyanoquinodimethane (TTF-TCNQ ) have metallic conductivity at room temperature. At the same time, tetrathiafulvalene and its derivatives are good molecular assembly materials, which can be matched with other functional material molecules to form intramolecular CT-complexes. This intramolecular charge transfer complex has multiple electrical, optical, and magnetic activities, and can be used as a molecular electronic device material for VLSI or as a "molecular switch" for future photonic computers, ...
