The use of soluble polymer-small molecule composites to polymer-based top-gate organic transistors can facilitate the solution processing of nonvolatile organic memories. We found that the addition of soluble fullerene derivatives to PMMA:TIPS-pentacene composite films allows achieving a large threshold voltage shift of over 40 V by photo-assisted programming.
