Miniaturized organic single-crystal arrays that are addressed by reading-out circuits are crucial for high performance and high-level integration organic electronics. Here, we report a lithography compatible strategy to fabricate organic single-crystal arrays via area-selective growth and solvent vapor annealing (SVA). The organic semiconducting molecules can first selectively grow on photographically patterned drain-source electrodes, forming ordered amorphous aggregates that can further be converted to discrete single-crystal arrays by SVA. This strategy can be applied to self-align the microsized organic single crystals on predesigned locations. With this method, suppression of cross-talk among devices, organic field-effect transistors, and basic logic gate arrays with reading-out electrodes are further demonstrated.
