The growth and self‐organization of organic crystals between a source (S) and drain (D) electrode by a method based on the use of a micropipette and isothermal evaporation of the solvent in a two‐liquid system led to the formation of organic‐crystal transistors (see polarized optical micrograph). The method is similar to ink‐jet printing and should be suitable for the fabrication of low‐cost and mass‐producible printed electronic devices.
