Source and drain functionalization with a light‐responsive azobenzene‐based self‐assembled monolayer (SAM) is used to modulate the charge injection at the Au electrode–semiconductor interface of an organic field‐effect transistor (OFET). This photochromic bistable SAM mediates the injection through the variation of the tunneling barrier across the SAM.
