Evidence for on-surface switching from angle-resolved NEXAFS spectroscopy. Angle-resolved NEXAFS spectra of (a) a Rot3 monolayer on AUD, (b) a Rot6 monolayer on PST (left, (TBA)Cl; right, (TMA)Cl), and (c) a Rot6 monolayer on TDT/DT (1:3). In each case, the NEXAFS results obtained for the pristine layer, that after chloride addition, and that after chloride removal with NaBArF4 are shown (top to bottom). Red and black lines represent the NEXAFS spectra obtained at 30° and 90° angles of the incident synchrotron light beam, respectively. Difference spectra are shown in green.
