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, H-1-NMR and mass spectroscopies. The Phi(F) values were 0.33, 0.08, 0.20 and 0.08 for 6-9, respectively. The Phi(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 tau(T) values of 710 (6), 170 (7), 1490 (8) and 380 mu s (9) in DMSO. These complexes offer potential as photosensitizers in photodynamic therapy.
