An organic optocoupler composed entirely of small molecules is shown to exhibit the highest current‐transfer ratio reported to‐date. Based on a photosensitive C 60 /NPB interfacial heterojunction, its frequency response is also significantly better than in previously reported systems. It suggests a new way in which organic optocouplers that behave comparably to commercial inorganic optocouplers may be achieved.
