Description
Summary:Chemically modified chlorophylls and porphyrins have been studied by 252Cf-plasma desorption mass spectrometry (PDMS). The 252Cf-PDMS spectra of thin films show intense molecular ions and fragmentation from whicn we make reasonable assignments for compound identification. The 252Cf-PDMS of two compounds, bis(10-hydroxybutoxy-methyl pheophorbide a )-1,4-dichlorophtalate and linear bis(tetraphenylporphyrin) are discussed.
