The synthesis and photophysical properties of peripherally and non-peripherally substituted ball-type Mg(II) and Zn(II) phthalocyanines.
Newly synthesized ball-type Zn(II) and Mg(II) phthalocyanines containing four 1,1'-binaphthol substituents at peripheral and non-peripheral positions are presented. The structures of the synthesized compounds were characterized by using elemental analysis, UV-vis, FT-IR, (1)H-NMR and mass spectroscopies. The Φ(F) values were 0.33, 0.08, 0.20 and 0.08 for 6-9, respectively. The Φ(T) values were 0.56, 0.85, 0.64 and 0.88 for 6-9, respectively. All the complexes showed reasonably large triplet lifetimes with τ(T) values of 710 (6), 170 (7), 1490 (8) and 380 μs (9) in DMSO. These complexes offer potential as photosensitizers in photodynamic therapy.
