Effect of S⋯π interactions on the charge transport properties of the DPP framework

Abstract

We find that the S⋯π interactions can form a new through-space channel that favors charge transport and consequently improves the electronic properties in DPP derivatives.

Molecular-Scale Electronics: From Individual Molecule Detection to the Application of Recognition Sensing

“…The BJ method, capable of creating thousands of molecular junctions in a short time, is widely utilized for constructing SMJs and measuring charge transport through individual molecules. This method involves rapid collision and separation between electrodes, which can be achieved using platforms or techniques such as scanning tunneling microscopy (STM), ,− conductive-atomic force microscopy (C-AFM), and mechanically controlled break junctions (MCBJ). , …”

“…With the advancement in SMJ construction methods, the one-molecule system is extensively studied. Initially, the focus of one-molecule systems was on researching the charge transport properties through individual molecules, which involved the investigation into the geometric structure of the molecule, intramolecular interactions, and the alignment of energy levels between electrodes and molecules. ,− Subsequently, extensive investigations have explored the impact of various physical stimuli on charge transport properties of the one-molecule system. These physical stimuli include electric fields, , electrochemical bias, mechanical forces, − thermal conditions, , light exposure, , and magnetic fields, − all of which contribute significantly to the modulation of SMJ behavior and characteristics.…”
