Photochemical properties of fluoro-chalcone substituted peripherally tetra Zn(II)Pc and Mg(II)Pc

Fluoro-chalcone substituted new metallophthalocyanines (MPcs) (M = Zn or Mg) derived from (2E)-1-(3-hydroxyphenyl)-3-(2,4,5-trifluorophenyl)prop-2-en-1-one were synthesized. The structures of chalcone compound 1, phthalonitrile derivative 2 and metallophthalocyanines 3, 4 were characterized by a combination of spectroscopic techniques such as "FT-IR, H-1 NMR, C-13 NMR, MALDI-TOF mass and UV-Vis" as well by elemental analysis. The aggregation behaviours and photochemical properties such as singlet oxygen and photodegradation quantum yields of the synthesized (ZnPc)-Pc-II 3 and (MgPc)-Pc-II 4 were examined in DMSO.
