Photoswitches: High Performance Photoswitches Based on Flexible and Amorphous D–A Polymer Nanowires (Small 2/2013)

Polymer nanowire photoswitches are integrated with flexible micro-optoelectronic panels by W. Hu, X. Zhan, and co-workers. On page 294, donor–acceptor polymer (PFTBT) nanowires are prepared on a large scale using a simple template-dipping method. The PFTBT individual nanowire photoswitches exhibit a photoresponsivity of 1700 mA W−1 and a photoswitch ratio of 2000 under a light intensity of 5.76 mW cm−2 and a driving voltage of 40 V. Even at low driving voltages of 2 V or with the nanowires bent at nearly 90 degrees, these devices exhibit highly reproducible on/off cycles with photoswitch ratios of over 200. Image designed by Y.
