铜酞菁 (CuPc) 纳米带场效应晶体管被用作化学传感器。它们在室温下四氢呋喃气氛的检测中表现出快速响应和高可逆性。当在四氢呋喃气氛下测量晶体管时，场效应晶体管传感器的漏极电流从 6.7 nA 降至 0.2 nA。传感器在几分钟内即可自我刷新。这些结果表明有机单晶纳米带晶体管可以有效地充当化学传感器。
Copper phthalocyanine (CuPc) nanoribbon field-effect transistors were implemented as chemical sensors. They showed fast response and high reversibility in the detection of the tetrahydrofuran atmosphere at room temperature. The drain current of the field-effect transistor sensor decreased from 6.7 to 0.2 nA when the transistor was measured under the tetrahydrofuran atmosphere. The sensor was self-refreshable in a few minutes. These results demonstrate that the organic single crystalline nanoribbon transistors could effectively act as chemical sensors.
