Abstract
An organic electronic layer is formed using a monomer dissolved in a solvent such as formic acid. The solution is oxidized with the aid of an oxidizing agent, chosen such that there are no ionic byproducts resulting therefrom. Additives such as polyacids, acids, salts and electrolytes may be added to the solution.
Claims44
An organic film, comprising:
- a solution containing a monomer dissolved in a solvent;
- and
- an oxidizing agent added to said solution, said solution allowed to oxidize without the presence of ionic byproducts thereby, said oxidized solution deposited and allowed to dry to form said film.
An organic light emitting device, comprising:
- an anode;
- an anode buffer layer disposed upon said anode, said anode buffer layer fabricated by depositing a solution containing a monomer dissolved in a solvent which is allowed to oxidize without the presence of ionic byproducts prior to deposition;
- and
- a light emitting layer disposed on said anode buffer layer, said light emitting layer capable of emitting light upon electron hole recombination therein.

A method of fabricating an anode buffer layer for an organic electronic device, said method comprising:
- forming a solution of a monomer and a solvent containing formic acid;
- adding an oxidizing agent to said solution;
- allowing said solution to oxidize, said oxidizing agent disallowing the presence of ionic byproducts during oxidation;
- and
- depositing said solution onto a surface in said organic electronic device.
