Abstract

A fluorene-based donor–acceptor conjugated polymer is synthesized and the polymer nanowires are successfully prepared with high quality and large scale using a simple and practical template dipping method. These amorphous polymer nanowires are flexible and show excellent photoconductive properties with reliable reproducibility. The individual nanowire photoswitches exhibit a responsivity as high as 1700 mA W−1 and an on/off ratio as high as 2000 under a light intensity of 5.76 mW cm−2 and a driving voltage of 40 V.
