Selectivity in single-molecule reactions by tip-induced redox chemistry
Sign Up to like & getrecommendations! Published in 2022 at "Science"
DOI: 10.1126/science.abo6471
Abstract: Controlling selectivity of reactions is an ongoing quest in chemistry. In this work, we demonstrate reversible and selective bond formation and dissociation promoted by tip-induced reduction-oxidation reactions on a surface. Molecular rearrangements leading to different… read more here.
