New nonperipherally and peripherally tetrasubstituted zinc(II) phthalocyanine complexes containing 1-benzylpiperidin-4-ol groups and their quaternized derivatives are reported in this work. These complexes were characterized successfully and their photophysical and photochemical properties were studied. These properties were determined in dimethylsulfoxide for all studied complexes and in water and water + Triton X-100 solutions for ionic Zn(II) phthalocyanines. All studied zinc(II) phthalocyanine complexes generated high singlet oxygen, especially in dimethylsulfoxide, and these properties make them potential photosensitizers for use in the photodynamic therapy of cancer. The effects of the position and quaternization of the substituents on the photophysical and photochemical properties were also examined. The fluorescence of the tetrasubstituted zinc(II) phthalocyanine complexes is effectively quenched by addition of 1,4-benzoquinone. Furthermore, the water soluble Zn(II) phthalocyanines can bind to bovine serum albumin, which is a blood plasma protein.

Amino group modified phthalocyanines (Pcs) and their derivatives have attracted great attention in the field of photodynamic therapy (PDT) because of their satisfied anticancer activity. The existence of N atoms in these Pcs is very important because they not only provide water solubility of Pcs, but also greatly affect their PDT activity. To clear the influence of N atoms number on PDT activity of amino group modified Pcs and their derivatives, in this manuscript, two series of amine modified Pcs with different N atom number and their water soluble derivatives, hydrochloride and quaternizing derivatives were synthesized. Their photochemical and photobiology properties were studied and compared. The results indicated that with increasing the number on N atom, the reactive oxygen species (ROSs) generation ability, cancer cell uptaken ability and photoinduced anticancer activity were all increased in these ZnPcs.
