Schiff base containing pyridine groups functionalized water-soluble phthalocyanine: Synthesis, photo-physicochemical properties, and bovine serum albumin binding behavior

The novel pyridine bearing schiff base substituted metal-free (9), zinc(II) phthalocyanine (10), and its quaternized derivative (11) were designed synthesized. These phthalocyanines fully characterized by spectroscopic methods (FT-IR, UV-Vis, MALDI-TOF, 1H NMR). photo-physicochemical properties of these investigated in both DMSO DMF for 10 aqueous solution 11. addition Schiff groups as peripheral ligands showed an improvement the photophysical photochemical properties. In addition, a investigation binding behavior water-soluble zinc (II) complex to bovine serum albumin (BSA) was also studied this work.
