A novel photoswitchable rotaxane was synthesised and its switching behaviour in solution was analysed with NMR and UV-VIS. A monolayer of rotaxanes was deposited on glass surfaces and the on-surface photoswitching was investigated. Angle-resolved NEXAFS spectra revealed a preferential orientation that reversibly changes upon switching.
