Problems solved by technology

Chinese invention patent (00131902.7) discloses a phthalocyanine / phthalocyanine composite single-layer organic photoconductor and its preparation method, but phthalocyanine only has excellent spectral response in the near-infrared region, so the organic composite photoconductor is only suitable for near-infrared light Laser printers with laser as the light source are also difficult to meet the needs of broadband response
The Chinese invention patent (97113319.0) uses azo / phthalocyanine blend compound as a carrier photogenerated material to prepare single-layer and double-layer organic photoconductors. Although it has excellent spectral response in the range of visible light to near-infrared light, However, the photosensitivity of single-layer photoconductors is still much lower than that of double-layer photoconductors.

Embodiment 1

[0029] The chemical structural formula is respectively:

[0030]

[0031] The oxazolyl disazo and titanium phthalocyanine (wherein, R 1 =OH, R 2 =Cl, M=TiO), mixed in a ratio of 1:1 (by wt.), added tetrahydrofuran and sanding medium, sanded at room temperature for 6 hours, and evaporated the solvent to obtain oxazolyl disazo and phthalocyanine Titanium complex. The oxazolyl disazo / phthalocyanine titanium complex, N, N'-diethyl-4-aminobenzaldehyde-1-phenyl-1'-α-naphthylhydrazone (α-naphthylphenylhydrazone) Stir and disperse in dioxane with polycarbonate at a ratio of 1:75:82 (weight ratio) to obtain an organic photoconductive coating solution. The above-mentioned coating solution is coated on the aluminum alloy drum base by dip coating, the coating speed is 5.5mm / s, the viscosity of the coating solution is 450cp, the drying temperature is 90°C, and the drying time is 3.5 hours. The dried organic The thickness of the photoconductive coating layer was 30 μm.

Description

technical field [0001] The invention belongs to the technical field of organic photoconductors, and specifically relates to an azo / phthalocyanine composite single-layer organic photoconductor with wide frequency response and high photosensitivity and a preparation method thereof. Background technique [0002] Organic photoconductors are the "heart" components of electrophotography imaging that can form photogenerated carriers and migrate under photoexcitation. At present, the annual output of organic photoconductors in the world is hundreds of millions, which has produced huge economic and social benefits. But there are still many problems to be solved. [0003] In order to obtain organic photoconductors with high photosensitivity and long life, traditional photoconductors use a single organic photogenerated carrier material and an organic carrier transport material for layered compounding to form a functionally separated double-layer organic photoconductor. . Due to mult...
