Enhancing performance characteristics of organic semiconducting films by improved solution processing

An electronic device comprising a first electrode, an organic semiconductor film having a first side and a second side, where the first side of the organic semiconductor film contacts the first electrode and where the film is formed by adding an amount of one or more low molecular weight alkyl-containing molecules to a solution used to form the organic semiconductor film, and a second electrode contacting the second side of the organic semiconductor film, wherein the one or more low molecular weight alkyl-containing molecules are selected from C4-C20 alkanes, C4-C16 alcohols, and C4-C16 thiols.
