Abstract

In this study, new silicon phthalocyanine compounds were synthesized. The new neutral compound 3 is reacted with excess dimethyl sulfate to obtain quaternized derivative; 3Q. For the synthesis of the zwitterionic complex, 3 and excess 1,3-propanedisultone were reacted in dry dimethylformamide for 24 h under nitrogen atmosphere. The structures of all compounds were characterized by using spectrophotometric techniques. Experiments which include the singlet oxygen generation and photoinactivation of the yeast Saccharomyces cerevisiae both in the absence and presence of light indicated that these compounds can be potentially used in photodynamic therapy or photoinactivation of some microorganisms.
