This work focused on design a novel combinational molecular device that mimics a Wheatstone bridge consisting of four single benzene molecules and a molecular wire that connects the upper arm with the lower arm together, this system is attached to two electrodes. All transport properties were investigated by using steady-state theoretical model of two different mechanisms in molecular switches, both electrostatic and conformational mechanisms. The results in the electrostatic mechanism show the operations can be controlled by a gating and magnetic flux, while the results in the conformational mechanism can be adjusted by torsion angle. The transmission probability and the electric current are calculated as output signals of the molecular Wheatstone bridge.

这项工作的重点是设计一种新型的组合分子装置，该装置模仿由四个单苯分子组成的惠斯通电桥和将上臂和下臂连接在一起的分子线，该系统连接到两个电极。使用分子开关中两种不同机理的稳态理论模型研究了所有传输性质，包括静电机理和构象机理。静电机理的结果表明，可以通过门控和磁通量来控制操作，而构象机理的结果可以通过扭转角来调节。计算出传输概率和电流作为分子惠斯通电桥的输出信号。
