Problems solved by technology

But these small molecule electron acceptors are very toxic and have poor stability
U.S. Patent 4,556,622 (1985) increases the solubility of perylene imide by introducing long alkyl chains and halogen atoms such as bromine and chlorine on perylene imide, so that perylene imide can be mixed with poly N-vinylcarbamate azoles are dissolved in tetrahydrofuran, and solution coating is carried out to obtain an organic photoconductor. Although this method brings simplicity in the process, it pays the price of a decrease in photosensitivity.

Abstract

The preparation process to single layer organic phhotoelectric conductor containing Fluoroperylene imide includes the steps of: mixing carrier generating material and carrier converying material in the weight ratio of 1 to 10-100 and dissolving in solvent to obtain organic photoconductive solution with solid content of 5-40 wt%; and dip coating the solution to conducting substrate and eliminating solvent to obtain single layer organic photoelectric conductor film of 5-40 micron thickness. The present invention uses Fluoroperylene imide as organic photoelectric conductor and prepares the photoelectric conductor through direct dissolving and coating process. The phoeoelctric conducting has high photosensitive sensitivity and small dark conductance and may be work in positive and negative voltage.

Description

technical field [0001] The invention relates to an organic photoconductor, in particular to a single-layer organic photoconductor containing fluorinated perylene imide and a preparation method thereof. Background technique [0002] New materials are the material basis of the new technological revolution. In today's wave of informationization, copiers and laser printers as information output devices are playing an increasingly important role, and the core components of copiers and laser printers are organic photoconductors. The structure of organic photoconductors is generally to coat one or more photosensitive layers mainly composed of carrier generation materials and carrier transfer materials on the conductive substrate, so that the organic photoconductor can generate photogenerated currents under light excitation. The particles are migrated to form electrostatic latent images, and under the action of toner, images are output on paper and other me...
