Abstract:
Photo-oxidation of iron(II)-phthalocyanine (PcFe) has been observed in matrix
assisted laser desorption/ionization (MALDI) and laser desorption/ionization
(LDI) and is interpreted by theoretical molecular dynamics simulations. The
two ionization methods show different amounts of μ-oxo-bridged PcFe-dimer and
deliver evidence that MALDI produces less mechanical stress on the analyte.
The typical proton-transfer in the MALDI-process does not occur which leads to
the assumption of a released electron of the delocalized π-system.
