Abstract:The structure of the 01s spectrum for the MC 540 merocyanine dye is resolved using data obtained from XPS analysis of a series of merocyanine dyes displaying less complex O1s signals.The 01s binding energy (BE) of the carbonyl group in these molecules is unusually low and the photoionization peak is accompanied in most cases by a satellite on the high BE side.The data obtained in this study permit a reconstruction of the 01s profile of the MC 540 molecule. The 01s binding energy thus obtained for the carbonyl groups in MC 540 is 531.2 eV. This BE is low when compared to those usually observed for such groups and indicates that, in the MC 540 molecule, they predominantly exist in the ⩾C-O−3 form.
