[Featured as a Cover Paper]

Molecular and crystal engineering rendered high-performance organic thin-film transistors (TFTs) based on a highly electron-poor octachloroperylene diimide (Cl8-PTCDI). In their Communication on page 740 ff., F. Würthner, Z. Bao, and co-workers report an intriguing supramolecular crystal engineering concept that directs two-dimensional π–π-stacked percolation paths for electron transport and affords TFTs with excellent mobilities and on-to-off current ratios under atmospheric conditions.
