The syntheses of new ball-type dinuclear Si(IV)(CH(3)COO)(2) and Ti(IV)O phthalocyanines and two different mononuclear Zn(II) and Ti(IV)O phthalocyanines containing four 1,1'-binaphthyl-8,8'-diol substituents on the peripheral positions are described. The structures of these compounds were characterized using the elemental analyzes, UV-Vis, FT-IR, (1)H NMR and mass spectroscopies. The Phi(F) values are 0.14, 0.10, 0.04, 0.02, 0.07; Phi(T) values are 0.69, 0.71, 0.85, 0.33, 0.71 for 7-11, respectively. All complexes showed very long triplet lifetimes with tau(T) 7510, 3190, 2880, 2370, 9470 mu s for 7-11 in DMSO, respectively.
