Semiconductors based on -conjugated small-molecules and polymers are widely studied as the active layer in a variety of electronic and opto-electronic devices. Currently, an increasing interest is directed towards embedding semiconductors in (semi-)crystalline commodity polymer matrix materials. This approach lead to outstanding active blends that under appropriate processing conditions feature excellent performance in OFETs and OPVs at remarkably low semiconductor contents,[1,2] thus offering the prospect for significant cost reduction as well as significantly enhanced stability of devices produced with them. Furthermore, the addition of a judiciously selected commodity polymer to the semiconducting small molecules/polymers is expected to increase solution viscosity, which provides, for example, improved film forming characteristics. In some cases, addition of a suitable polymer is imperative to meet the ink rheology requirements for specific printing steps.
