Embodiment example 1

[0030] The present invention provides the preparation method of the polyiodine 3-methylaminothiophene salt photoconductive compound, and its synthetic route is as follows Figure 9 as shown,

[0031] Specifically include the following steps:

[0032] Add hydrogen iodide aqueous solution and 3-methylaminothiophene to ethanol in a certain proportion, stir and place under light, let it stand for 12 to 24 hours, and then dry the solvent on a 40-degree hot table to obtain a dark brown solid. Wherein, the ethanol solvent can be other low-boiling polar solvents; the ratio between hydrogen iodide and 3-methylaminothiophene is 2:1.

Embodiment example 2

[0034] The preparation method of the polyiodomethylamino phenyl salt photoconductive compound is provided in the present invention, and its synthetic route is as follows Figure 10 as shown,

[0035] Specifically include the following steps:

[0036] Add hydrogen iodide aqueous solution and methylaminobenzene to ethanol in a certain proportion, stir and place under light, let it stand for 12 to 24 hours, and then place it on a 40-degree hot table to dry the solvent to obtain a dark brown solid. Wherein, the ethanol solvent can be other low-boiling polar solvents; the ratio between hydrogen iodide and methylaminobenzene is 2:1.

Embodiment example 3

[0038] The present invention provides the preparation method of the polyiodine 3-methylaminothiophene salt photoconductive compound, and its synthetic route is as follows Figure 11 as shown,

[0039] Specifically include the following steps:

[0040] Add sodium iodide, simple iodine and 3-methylaminothiophene to ethanol in a certain proportion and stir, adjust the pH of the solution to 1-4 with hydrochloric acid, dry the solvent at 50-60 to obtain a dark brown solid. Wherein, the ethanol solvent can be other low-boiling polar solvents; the iodine salt can be NaI, KI, HI. The ratio of iodine salt to simple iodine is 1:1, and the ratio between the total iodine content and 3-methylaminothiophene is 3:1 to 2:1.

Abstract

The invention relates to a compound of a polyiodide ionic salt, a preparation method and application of the compound as a novel photoconductive material to a photoconductive device. The compound is simple in preparation method, is low in preparation cost, has high photoconductive property and short response time, and is a novel organic-inorganic compound photoconductive material based on polyiodide ions.

Description

technical field [0001] The present invention relates to photoconductive materials and polyiodide compounds. Specifically, it relates to polyiodide compounds, preparation methods and applications as photoconductive materials in optoelectronic devices. Background technique [0002] Photoconductive materials are an important part of making photoconductors. Photoconductive materials are divided into two categories, inorganic photoconductive materials and organic photoconductive materials. Inorganic photoconductive materials such as selenium, selenium tellurium alloy, cadmium sulfide, zinc oxide, etc. Organic photoconductive materials include phthalocyanine complexes, azo compounds, polyvinylcarbazole, and the like. Because inorganic photoconductive materials are highly toxic and expensive; organic photoconductive materials are mainly sensitive to near-infrared light. Contents of the invention [0003] purpose of invention [0004] The purpose of the present invention is t...
