The effect of weak π–π interactions on single-molecule electron transport properties of the tetraphenylethene molecule and its derivatives: a first-principles study

Abstract

The extremely weak π–π interactions in the V-shaped configurations are able to provide special through-space electron transport pathways.

“…However, our recent findings have shown that additional conducting channels could be present in non-face-to-face aligned thiophenes or phenyl-thiophene within benzodithiophene (BDT) derivatives. 31,77 These studies have expanded our understanding of intermolecular charge transport between two molecules, which is essential for elucidating the fundamental mechanisms behind biological processes 78 and organic electronics. 79 Chemical Reactions.…”

“…In recent years, significant progress has been made in studying intermolecular π–π stacking interactions. , Moreover, σ–σ and S–S intermolecular interactions in double-molecule systems have also been discovered and further explored. − Additionally, it was previously believed that through-space conductance channels existed only in closely stacked benzene rings with π–π interactions. However, our recent findings have shown that additional conducting channels could be present in non-face-to-face aligned thiophenes or phenyl-thiophene within benzodithiophene (BDT) derivatives. , These studies have expanded our understanding of intermolecular charge transport between two molecules, which is essential for elucidating the fundamental mechanisms behind biological processes and organic electronics …”
