Organic molecules enable the fabrication of large-area and flexible electronics with low energy consumption. In organic field-effect transistors (FETs), the charge transport mainly occurs in the first few nanometers of the semiconductor at the dielectric-organic interface.<br/>Herein, we present the method of self-assembled monolayers (SAMs) as functional layers in FETs, which combine dielectric and semi-conductive properties in one molecular layer with full control of surface coverage and high reliability in layer formation from solution. We will show newly designed organic molecules with specific anchor groups and molecular design as a tool box for p- and n-type self-assembled monolayer field-effect transistors (SAMFETs). We will demonstrate SAMFET devices based on small molecules and oligomer motifs. Additionally we will provide an integration concept, what enable the fabrication of organic complementary FETs as well as the realization of integrated circuits based on SAMFETs.
