Key Points

The central aim is to investigate if strong electronic effects can influence single-molecule conductance despite conformational distortions.
Synthesis of 2,5-bis(4-(methylthio)phenyl)pyrrole derivatives
Electronic property measurements of synthesized compounds
Analysis of conductance variations based on substituent effects
Certain substituents significantly altered single-molecule conductance
Electronic effects were observed to counteract conformational distortions
Implications for future molecular electronics applications were suggested

Implication

Experimental study investigates tuning single-molecule conductance via substituents in derivatives, suggesting possible manipulation strategies.

Abstract

Whether a strong electronic effect can overcome a severely distorted conformation in determining single-molecule conductance remains unclear. Here we address this question through a series of 2,5-bis(4-(methylthio)phenyl)pyrrole (BTPP) derivatives functionalized...
