Fig. 1: UV-driven and plasmon-induced [4+4]-cycloaddition.

a, b Chemical structure of monomers 1 and 2, respectively. c The reversible photochemical reaction between two anthracenes. The [4+4]-photocycloaddition reaction can be triggered by UV laser irradiation (365 nm, ca. 3.40 eV) and can also be reversed by irradiation at shorter wavelengths or thermally. d Schematic illustration of the monomer ML on Au(111). e Schematic illustration of the TERS imaging for the plasmon-induced 2DP ML under visible laser irradiation (633 nm, ca. 1.96 eV). λ, wavelength. hν laser light. ∆ heating.
