The design and fabrication of PTh-PPY heterojunction nanowires that exhibits smart responses to electrochemical redox potentials is described. In their oxidized state, PTh-PPY nanowires act as resistors, whilst in their reduced state, they acts as diodes. Furthermore, the electrical transport mode can be reversibly changed by alternately exposing the nanowires to negative and positive potentials. Constructing full-organic heterojunction nanowires with smart, controllable properties will contribute to the development of intelligent organic devices and organic-electronic circuits on the nanoscale.
本文描述了一种对电化学氧化还原电势具有智能响应的 PTh-PPY 异质结纳线的设计和制备。在其氧化态下，PTh-PPY 纳线充当电阻器，而在其还原态下，它充当二极管。此外，通过交替将纳线暴露于负电势和正电势，可以可逆地改变其电输运模式。构建具有智能、可控性能的全有机异质结纳线将有助于智能有机器件和纳米尺度上的有机电子电路的发展。
