Tuning Single-Molecule Conductance via Substituents at the 1-Position of a 2,5-Diarylpyrrole Core

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
