Extensive intramolecular π‐conjugation is considered to be requisite in the design of organic semiconductors. Here, two inkjet pigments, epindolidione and quinacridone, that break this design rule are explored. These molecules afford intermolecular π‐stacking reinforced by hydrogen‐bonding bridges. Air‐stable organic field effect transistors are reported that support mobilities up to 1.5 cm 2 /Vs with T 80 lifetimes comparable with the most stable reported organic semiconducting materials.
