Popis: Enhancing the gating performance of single-molecule conductance is significant for realizing molecular transistors. Herein, we report a new strategy to improve the electrochemical gating efficiency of single-molecule conductance with fused molecular structures consisting of heterocyclic rings of furan, thiophene, or selenophene. One order magnitude of gating ratio is achieved within a potential window of 1.2 V for the selenophene-based molecule, which is significantly greater than that of other heterocyclic and benzene ring molecules. This is caused by the different electronic structures of heterocyclic molecules and transmission coefficients
