AFM topography images recorded in air; a) ${\left[\mathrm{Co}{\left(\mathrm{dmgH}\right)}_2{\left(\mathrm{py}\right)}_2\right]}^{+}{\left[\mathrm{Co}{\left({\mathrm{dmgBPh}}_2\right)}_2{\mathrm{Cl}}_2\right]}^{-}$ and b) [Co(dmgH)₂(py)Cl] spots. c) and d) Height profiles before illumination (grey), after 15 h of illumination (red) and after 30 h of illumination (blue) in 0.5 mM Ru(mmip) and 0.1 M ascorbic acid solution (pH 4). e) and f) The change in height of 8 spots for each catalyst. (Note: in (e) only data before and after 15 h were recorded for spot 1).
