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, 1 H NMR, 13 C 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 Zn II Pc 3 and Mg II Pc 4 were examined in DMSO.
