Problems solved by technology

[0009] However, the compatibility of diphenoquinone derivatives such as 3,5-dimethyl-3', 5'-di-tert-butyldiphenoquinone and binder resins described in Patent Document 1 is insufficient. It can also be seen from the sensitivity test recorded in that the sensitivity is not sufficient

Embodiment

[0092] Hereinafter, the present invention will be described more specifically by way of examples. In addition, this invention is not limited to an Example.

[0093] [Synthesis of Pentabenzoquinone Derivatives]

Synthetic example 1

[0095] The synthesis of the pentabenzoquinone derivative represented by the chemical formula (1-1) proceeds as follows according to the following reaction formula (1-1).

[0096]

[0097] Reaction formula (1-1)

[0098] Under an inert gas, the THF (tetrahydrofuran) solution of 0.92 g (3.7 mmol) of the compound represented by formula (3-1) was cooled to -78 ° C, and a n-butyllithium hexane solution with a volume molar concentration of 1.6 M was added dropwise 2.33ml (3.7mmol), stirred for 1 hour. Then, 0.5 g (1.5 mmol) of the compound represented by the formula (2) was added, and the mixture was refluxed for 2 hours. Then, the THF solution was returned to room temperature, poured into water, extracted with ether, and the solvent was distilled off to obtain a residue.

[0099] Then, a solution of 9.2 g (40.5 mmol) of tin (II) chloride in 10 ml of dilute hydrochloric acid was added to the residue, followed by stirring at room temperature for 1 hour. Then, water was poured i...

Synthetic example 2

[0102] The synthesis of the pentabenzoquinone derivative represented by the chemical formula (1-2) proceeds as follows according to the following reaction formula (1-2).

[0103]

[0104] Reaction formula (1-2)

[0105]

[0106] Using 0.95 g of the compound (iodide) represented by the formula (3-2) in the same molar amount instead of the compound represented by the formula (3-1), the reaction was carried out in the same manner as in Synthesis Example 1, thereby obtaining the chemical formula 0.25 g of the pentabenzoquinone derivative shown in (1-2). The yield is 30%. Furthermore, the compound (iodide) represented by formula (3-2) is synthesize|combined from the aniline compound represented by formula (3-3) using a diazonium reaction.

Abstract

The invention provides an electronic photographic sensitive body and a manufacture method thereof. The electronic photographic sensitive body is the electronic photographic sensitive body with a conductive base body and a sensitive layer. The electronic photographic sensitive body is characterized in that the sensitive layer comprises pentacenequinone derivatives shown as the following general formula (1), wherein in the general formula (1), R is alkyl with the carbon atom number between 1 and 8, alkoxy with the carbon atom number between 1 and 8, aryl with the carbon atom number between 6 and 12, aralkyl with the carbon atom number between 7 and 12, cycloalkyl with the carbon atom number between 3 and 10 or heterocyclic radical with the carbon atom number between 3 and 10, and the aryl, the aralkyl, the cycloalkyl and the heterocyclic radical can be substituted by the alkyl with the carbon atom number between 1 and 8. The invention can provide the electronic photographic sensitive body with the improved photographic sensitivity and the manufacture method thereof.

Description

technical field [0001] The present invention relates to electrophotographic photoreceptors used in image forming apparatuses such as electrostatic copiers and laser beam printers, and methods for producing the same, and particularly to electrophotographic photoreceptors excellent in sensitivity and methods for producing the same. Background technique [0002] The electrophotographic photoreceptor of an image forming apparatus using the Carlson method includes an organic photoreceptor in which an organic material is used for a photosensitive layer and an inorganic photoreceptor in which an inorganic material such as selenium is used for a photosensitive layer. Compared with inorganic photoreceptors, organic photoreceptors are easy to manufacture, and there are various options for photoreceptor materials such as charge generators, charge transport agents, and binder resins, and the degree of freedom in structural design is large, so it has been extensively studied. Research. ...
