Abstract:
1. A method of forming an organic semiconductor film, comprising the steps of adding an amount of one or more low molecular weight molecules to a solution of one or more organic semiconductors, and forming the organic semiconductor film from the solution, wherein the low molecular weight molecules are selected from the group consisting of C 4 -C 20 alkanes substituted with one or more substituents selected from aldehyde, dioxo, hydroxy, thiol, thioalkyl, amine, amide, thioether, and epoxide groups, with the proviso that if a thiol or hydroxy group substituent is present, at least one independently chosen additional substituent must also be present; wherein the organic semiconductor film comprises a conjugated polymer film electron donor and an organic electron acceptor, or the organic semiconductor film comprises a conjugated polymer film electron acceptor and an organic electron donor.
