Solution-processed organic semiconductors enable the fabrication of large-area and flexible electronics by means of cost-effective, solution-based mass manufacturing techniques. However, for many applications an insoluble active layer can offer technological advantages in terms of robustness to processing solvents. This is particularly relevant in field-effect transistors (FETs), where processing of dielectrics or barriers from solution on top of the semiconductor layer typically imposes the use of orthogonal solvents in order not to interfere with the nanometer thick accumulation channel. To this end, the use of latent pigments, highly soluble molecules which can produce insoluble films after a post-deposition thermal cleavage of solubilizing groups, is a very promising strategy. In this contribution, we demonstrate the use of tert-butyloxycarbonyl (t-Boc) functionalized diketopyrrolopyrrole and perylene-diimide small …
