Abstract
A process of forming an electronic device is disclosed. An organic device layer is formed. The organic device layer includes a charge-selective material and a radiation sensitizer and has a first electrical conductivity and a first surface energy. First portions of the organic device layer are selectively exposed to radiation. The electrical conductivity and surface energy of the first portions of the organic device layer are modified.
Claims12
A process of forming an electronic device comprising:
- forming an organic device layer comprising a charge-selective material, a radiation sensitizer, and a small molecule photocurable surface-active composition, said layer having a first electrical conductivity and a first surface energy;
- and
- selectively exposing portions of the organic device layer to radiation resulting in exposed areas and unexposed areas, and
- applying a development treatment,
- wherein the electrical conductivity of the exposed areas of the organic device layer is less than the first electrical conductivity, and the surface energy of the exposed areas of the organic device layer is less than the first surface energy.
