A Crystal‐Engineered Hydrogen‐Bonded Octachloroperylene Diimide with a Twisted Core: An n‐Channel Organic Semiconductor

Twisted up: Perchlorination of perylene diimide afforded an exceptionally electron-poor organic semiconductor molecule (see picture; C black, Cl green, O red, N blue, H white) that crystallizes in an ideal brickstone arrangement with close π–π and chlorine–chlorine contacts. Vapor-deposited thin films of this molecule show excellent transistor performance, even in air (μ≈0.8 cm2 V−1 s−1, Ion/Ioff≈108).
