Abstract
An organic optoelectronic device includes a solution coatable thin film having a hole transporting material, an electron transporting material, and a photogenerating component uniformly dispersed therein. The thin film is about 0.2 microns or less, and can be spin-coated onto a substrate and further coated with electrodes.

A solution coatable thin film comprising a binder having uniformly dispersed therein at least one of each of:
- a hole transporting functional component;
- an electron transporting functional component;
- and
- a photogenerating component,
- wherein the hole transporting functional component and the electron transporting functional component together comprise about 20 to about 80 weight percent of the thin film, and
- wherein the thin film has a thickness of about 0.2 microns or less.
A process of making a solution coatable thin film, comprising:
- mixing at least one hole transporting functional component, at least one electron transporting functional component, at least one solvent, at least one electrically inactive resin binder, and at least one photogenerating component to form a solution;
- and coating the solution onto a substrate to form the thin film having the at least one hole transporting functional component, the at least one electron transporting functional component, and the at least one photogenerating component uniformly dispersed therein,
- wherein the hole transporting functional component and the electron transporting functional component together comprise about 20 to about 80 weight percent of the thin film, and
- wherein the thin film has a thickness of about 0.2 microns or less.
A xerographic device comprising an organic optoelectronic device comprising solution coatable thin film having uniformly dispersed therein at least one of each of a hole transporting functional component, an electron transporting functional component, and a photogenerating component,
- wherein the hole transporting functional component and the electron transporting functional component together comprise about 20 to about 80 weight percent of the thin film, and
- wherein the thin film has a thickness of about 0.2 microns or less.
