“…Firstly, the monitoring of single-molecule charge transport properties and quantum behavior under electric fields is presented. We focus on the modulation of single-molecule charge transport by electric fields for different types of chemical reactions and various modulations of single-molecule chemical reaction mechanisms, including Diels–Alder reactions [ 17 , 44 , 45 , 55 ], cleavage reactions [ 41 , 42 ], and coupling reactions [ 43 ]. Next, the monitoring of single-molecule redox reaction processes in electron effects is presented to explore the effect of electron energy on chemical reactions [ 46 ].…”

“…Electric fields can also regulate the direction of the chemical reaction. Hu et al reported the first example of in situ label-free single-molecule detection of thermally reversible DA reactions using a scanning tunneling microscopy break junction (STM-BJ) technique equipped with a thermocouple mounted under a substrate with feedback control [ 44 ]. The thermally reversible DA reaction using anthracene-2,6-diamine (AnAm) as the diene and fullerene C 60 as the pro-diene is shown in Figure 4 A.…”

“…In this review, we briefly summarized the significant catalytic roles of electric fields on the scale of single-molecule chemical reactions. The catalytic effects of electric fields on the Diels–Alder, cracking, and coupling reactions and the mechanism of the reaction were investigated by relating the electric field intensity [ 41 , 42 , 43 ] and the electric field direction [ 17 ] to the direction of the chemical reaction [ 44 , 45 ]. We also summarize the catalytic role of electronic effects in chemical reactions at the single-molecule scale [ 46 ].…”

The role of catalysis in controlling chemical reactions is crucial. As an important external stimulus regulatory tool, electric field (EF) catalysis enables further possibilities for chemical reaction regulation. To date, the regulation mechanism of electric fields and electrons on chemical reactions has been modeled. The electric field at the single-molecule electronic scale provides a powerful theoretical weapon to explore the dynamics of individual chemical reactions. The combination of electric fields and single-molecule electronic techniques not only uncovers new principles but also results in the regulation of chemical reactions at the single-molecule scale. This perspective focuses on the recent electric field-catalyzed, single-molecule chemical reactions and assembly, and highlights promising outlooks for future work in single-molecule catalysis.
