X-ray-Induced Reversible Switching of an Azobenzene Derivative Adsorbed on Bi(111)
Get PDFWe report on the adsorption of a submonolayer of di-m-cyanoazobenzene (DMC) on
Bi(111) and on the reversible switching of these molecules induced by resonant
X-ray illumination. DMC adsorbs in at least two configurations, the flat trans
and the nonflat cis isomer. We find that in 0.8 monolayers at least 26% of the
molecules change their configuration at 110 K by excitation of the N1s → LUMO
transition at the azo group, and by a thermally induced back reaction at 120
K. Nonresonant excitation with X-ray light does not induce any reversible
changes
