2,2,3,3-Tetrafluoropropoxy substituted oxo-titanium phthalocyanines axially ligated with common MALDI matrix materials

The synthesis of tetra and octa 2,2,3,3-tetrafluoropropoxy substituted oxo-titanium phthalocyanines (TiOPc) are reported. Using strongly chelating oxygen donor ligands, the reactions of TiOPc with catecholate (1a, 2a), 4-nitrocatecholate (1b, 2b) and caffeic acid (1c, 2c), ellagic acid (1d, 2d) and chlorogenic acid (1e, 2e) are described. The new compounds were characterized by mass, H-1 NMR, FT-IR, and UV-vis spectroscopic techniques as well as elemental analysis.
