“…Accompanied by the absence or presence of DQI, the corresponding molecular devices may present two states with a great difference in the conductance. This will find important applications in various fields, such as molecular switches, 25 logic gates, 26 data storage, 27 field effect transistors, 28,29 sensors, 30,31 molecular thermoelectric devices [32][33][34] and even molecular isomer identification. 35 Consequently, it has attracted intensive attention in recent years.…”
