Ribbons of an air‐stable, n‐type organic single‐crystal semiconductor , F 16 CuPc, are used to study photoswitches and phototransistors. High‐quality, reversibly switching, fast photoswitches together with strongly photodependent field‐effect phototransistors (see figure) of F 16 CuPc are made. The high light sensitivity and large on/off ratio of the phototransistors realize a new way to detect light and magnify signals in a single organic device, indicating a future in low‐cost, ultrahigh density, organic photoelectric integration.
