dc.description.abstract
For probing the nature of spin-state switching in spin-crossover molecules
adsorbed on surfaces, x-ray absorption spectroscopy has emerged as a powerful
tool due to its high sensitivity and element selectivity in tracing even
subtle electronic, magnetic, or chemical changes. However, the x-rays itself
can induce a spin transition and might have unwanted influence while
investigating the effect of other stimuli such as temperature or light, or of
the surface, on the spin switching behaviour. Herein, we present the spin
switching of an Fe(II) complex adsorbed on a highly oriented pyrolytic
graphite surface with particular emphasis on the x-ray-induced switching. For
a submonolayer coverage, the complex undergoes a complete and reversible
temperature- and light-induced spin transition. The spin states are switched
both ways by x-rays at 5 K, i.e. from the high-spin state to the low-spin
state or vice versa, depending on the relative amount of each species.
Furthermore, we quantify the fraction of molecules undergoing soft x-ray-
induced photochemistry, a process which results in an irreversible low-spin
state component, for a particular exposure time. This can be greatly
suppressed by reducing the beam intensity.
