Enhancing the gating performance of single-mol. conductance is significant for realizing mol. transistors. Herein, we report a new strategy to improve the electrochem. gating efficiency of single-mol. conductance with fused mol. 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 mol., which is significantly greater than that of other heterocyclic and benzene ring mols. This is caused by the different electronic structures of heterocyclic mols. and transmission coefficients T(E), and preliminary resonance tunneling is achieved through the HOMO at high potential. The current work exptl. shows that electrochem. gating performance can be significantly modulated by the alignment of the conducting orbital of the heterocyclic mol. relative to the metal Fermi energy. In the experimental materials used by the author, we found 2,5-Dibromothiophene(cas: 3141-27-3Safety of 2,5-Dibromothiophene)
2,5-Dibromothiophene(cas: 3141-27-3) , is mainly used as pharmaceutical intermediate and synthesis intermediate. 2,5-Dibromothiophene may be used as starting reagent for the synthesis of α,α′-didecylquater-, -quinque- and -sexi-thiophenes.Safety of 2,5-Dibromothiophene
