Fabrication of organic electronic circuits by contact printing techniques

A method for fabricating an organic conductor path on a substrate, comprising:

• (a) providing a substrate;
• (b) providing a printing stamp with a patterned printing side situated thereon, the patterned printing side including elevated sections and recessed sections arranged between the elevated sections that correspond to a structure to be imaged;
• (c) loading of the patterned printing side with a printing medium containing at least one conductive organic polymer or a precursor thereof;
• (d) removing any excess printing medium from the elevated sections of the patterned printing side such that the printing medium remains only in the recessed sections of the patterned printing side;
• (e) mutually arranging and aligning the substrate and the patterned printing side of the printing stamp with respect to each other and bringing the patterned printing side into contact with the substrate;
• and
• (f) removing the printing stamp from the substrate so as to transfer the printing medium situated in the patterned printing side onto the substrate;
• wherein the patterned printing side includes a hydrophobic interface, the substrate includes a hydrophilic interface and the printing medium is hydrophilic.
