Description
Technical field
The present invention relates to a kind of single layer structure organic light receptor and preparation method thereof and special raw material and method for making of just charging, particularly adopt by the nano particle of phthalocyanines organic light-guide material and just charging single layer structure organic light receptor of nano wire preparation and preparation method thereof.
Background technology
As the core component of laser printer and Xerox, light receptor has experienced the evolution that is become organic light-guide material by inorganic light-guide material.United States Patent (USP) U.S.Pat.No.4 for example, 265,990 have described a kind of preparation method of function divergence type organic light receptor.In the practical application at present is function divergence type bilayer or sandwich construction organic light receptor, and it produces layer by restraining barrier, charge carrier and electric charge migrating layer is formed.Because the research to hole transporting material is comparatively ripe, the working method that the light receptor in the practicality at present adopts the surface to fill negative electricity.Very high to the coating quality requirement in the organic light receptor preparation process, the multi-layer coated cost that makes significantly increases; Need to inject migrating layer after charge carrier produces during the work of multilayer light receptor, quantum yield is descended; When filling negative electricity, charger unit produces O
3Working environment is worsened, and device is easy to oxidation; The negative charging of corona discharger duty is not as the stable working state of just charging.From reducing production costs, improve the photoconduction current sensitivity, improve working environment, improve light receptor life-span, constant product quality, and aspect such as machine works state stability sets out, the surface single layer structure organic light receptor that just charging is from now on an important development direction.In addition, still there is some other key factors individual layer light receptor that determined just to charge to have very wide application prospect.
On the other hand, the light receptor skin that uses at present is electric charge migrating layer, and it is made of the complex that unsaturated organic compound and resin as transport materials form, and the stability of these compounds can not show a candle to phthalocyanines light-guide material itself.Therefore reduce this type of charge transporting material or do not use this type of charge transporting material to help improving the life-span of organic photoconductor fully.The phthalocyanine light-guide material that is used to make organic light receptor at present is the nano particle of size in sub-micrometer range, the size that further reduces light-guide material helps improving the spatial resolution of light receptor, improve the light transmission of light receptor, increase the light-guide material specific surface, produce efficient thereby improve charge carrier.Use the light-guide material nano wire can increase the charge separation degree, reduce the charge recombination probability, thereby improve light receptor photoconductivity energy.Chinese invention patent ZL95,117928.4 have at first reported a kind of manufacture method of ultrafine nanometer phthalocyanines optical conductor particle, and have prepared the ultrafine nanometer phthalocyanines organic light-guide material of the function admirable that is used to constitute the double-decker light receptor.
About the more existing patent reports of the development of single layer structure light receptor, for example at United States Patent (USP) (U.S.Pat.No.3,121,006) reported a kind of by the electric insulation resin bonding agent be scattered in the photoconduction electrolemma that ultra-fine inorganic light-guide material is wherein formed in, its inorganic light-guide material is mainly ZnO, resin is mainly polycarbonate, polyester and polyamide etc.Day disclosure special permission communique (A) (spy opens flat 7-291876) has been reported a kind of four component surfaces single layer structure organic light receptor that just charging, its carrier generation materials is a metal-free phthalocyanine, contains electron transfer material tetraphenylcyclopentadienone derivant and hole transporting material hydrazone compounds in addition.The spectral response range of metal-free phthalocyanine makes it to be difficult to be applied to the near infrared light of wavelength greater than 760nm.
Summary of the invention
The purpose of this invention is to provide new just charging single layer organic photoreceptor, it has good photoconduction electricity combination property and excellent stability.The present invention also provides the method for making this light receptor and has been used to make the Performances of Novel Nano-Porous meter level phthalocyanines organic light-guide material of this light receptor and makes new method.
The difficulty that runs in the manufacturing of individual layer light receptor mainly is to adopt common material to be difficult to satisfied requirement to the light receptor combination property.For example, good light receptor should have the high charge current potential simultaneously, better photosensitivity, low dark-decay, low rest potential and advantages of excellent stability.Wherein difficult especially is to solve high photoconduction current sensitivity and this a pair of principal contradiction of low dark-decay, and it is the key factor of restriction individual layer light receptor practicability.
Phthalocyanine-like compound (molecular structure as shown in Figure 1) particularly VOPc, TiOPc etc. has the spectral response range that good photo-generated carrier produces performance and broad, is widely used in making the charge carrier generation layer of laser printer light receptor.But (size concentrates on the nano particle between 20～200 nanometers using common phthalocyanines light-guide material, and contain some micro-size particless) when making individual layer light receptor film, because of the phthalocyanines optical conductor itself has dispersion on certain electric conductivity and the unavoidable microcosmic problem of bringing such as inhomogeneous, make some position dark-decay of film very big, and other position photoconductivities are relatively poor.High concentration use common phthalocyanine light-guide material because of dark-decay is too big can't practicability.
The present invention uses specific process to produce Performances of Novel Nano-Porous meter level phthalocyanines organic light-guide material, and it is made of phthalocyanines nano particle and nano wire.Wherein the nano particle mean grain size is in 2～100 nanometers, and 2～50 nanometer range particularly, nano wire mean diameter are in 2～30 nanometers, particularly 2～10 nanometer range.This type of light-guide material is dispersed in the electrical insulating property film forming agent, makes novel individual layer light receptor.Because the thickness of light receptor film to the millimeter level, so is difficult to form the dark conduction passage that runs through at micron in the film, thus when principle has solved higher phthalocyanine light-guide material content the excessive problem of dark conductance.Simultaneously because small size phthalocyanine light-guide material has excellent light transmission and very big specific surface, and suitable spacing is arranged between the particle of high degree of dispersion, the existence of a large amount of light-guide material nano wires increases the charge separation degree, thereby (400～900nm) these light receptors all show good photoconduction performance in the visible-near-infrared spectrum responding range, it is better photosensitivity, low dark-decay, low rest potential and good charged ability.
Particular content of the present invention is as follows:
