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 rule are explored. These molecules afford intermolecular π-stacking reinforced by hydrogen-bonding bridges. Air-stable field effect transistors reported support mobilities up 1.5 cm2/Vs with T80 lifetimes comparable most stable semiconducting materials.
