Embodiment 1

[0096] A patterned base layer having a highly ordered nano- to micro-scale pattern, such as a layer with equidistant pores, was prepared using monocarboxy-terminated polystyrene in toluene. The patterned base layer is prepared by coating at a relative humidity of about 50% to about 90%, a temperature of about 20°C to about 30°C, and an air flow of about 500 mm / s to about 500 cm / s. An ordered thin film is displayed on the charge generation layer of a photoconductive imaging element. The pores in these patterned binder layers are filled with N,N'-diphenyl-N,N'-bis(3-hydroxyphenyl)-1,1'-biphenyl-4,4'-diamine , a hole transport material whereby columnar domains are formed, such as nanowires or microwires with a high concentration of hole transport material.

Embodiment 2

[0097] A highly ordered A patterned substrate layer of a nanometer to micrometer scale pattern, ie a layer with equidistant pores. The patterned base layer is prepared by coating at a relative humidity of about 50% to about 90%, a temperature of about 20°C to about 30°C, and an air flow of about 500 mm / s to about 500 cm / s. A patterned base material layer is prepared on the charge generation layer of the photoconductive imaging member. The pores in the patterned binder layer are filled with a solution with a polyol binder such as DESMOPHEN 800, a melamine curing agent such as CYMEL 1130, and an acid catalyst such as p-toluenesulfonic acid. The patterned substrate layer is heated to about 110° C. to about 130° C. to crosslink the material in the pores, thereby forming columnar domains of high strength material.

Abstract

The invention discloses a photoreceptor device having a base layer forming picture by self assembly, which is provided with at least one layer being the base layer forming picture by self assembly, capable of comprising at least one function material.

Description

technical field [0001] A photoreceptor device is disclosed herein, and more particularly, a photoreceptor device having at least one layer, which is a self-assembled patterned base layer, may include at least one functional material. Background technique [0002] Photosensitive elements, such as electrophotographic or photoconductive imaging elements, include photoreceptors or photoconductors, typically including a photoconductive layer formed on a conductive substrate or on a layer between the substrate and the photoconductive layer. The photoconductive layer is an insulator in the dark, allowing charges to remain on its surface. When exposed to light, the charge is consumed and an image can be formed thereon, developed using a developer material, transferred to a replicating substrate, and fused thereto to form a replica or print. [0003] Known organic photoreceptors use a polymer base as a holding medium for functional materials. Such functional materials may include c...
