Abstract
Organic electronic devices having a conducting self-doped polymer buffer layer, particularly a self-doped polyaniline buffer layer, are described. Also described are organic light emitting diodes with buffer layers comprised of an intrinsically conducting polymer having no mobile counterions.
Claims10
A small molecule organic electronic device comprising:
- an electrode layer adjacent to
- a buffer layer comprising a conducting self-doped polymer, and a layer consisting essentially of non-polymeric small molecule material adjacent the buffer layer.
A small-molecule organic light emitting diode comprising
- an anode layer,
- a single buffer layer comprising an intrinsically conducting polymer having no mobile counterions, wherein the anode layer is adjacent one side of the buffer layer and a layer consisting essentially of non-polymeric small molecule material is adjacent the other side of the buffer layer.
The organic light emitting diode of claim 9 wherein the anode layer is transparent or semitransparent, and the intrinsically conducting polymer is self-doped polyaniline.
