Construction of high-performance, low-cost, and flexible n-type organic transistors with robust stability is a critical challenge in organic electronics. Chong-an Di and co-workers demonstrate on p. 2448 all-solution-processed circuits with powerful performance and excellent ambient stability based on flexible n-channel transistors. The cover image shows the ultralow-cost construction of organic paper-like circuits from drops of functional materials under ambient conditions, which constitutes a unique advantage of organic devices with inorganic counterpart.
