    Abstract

    A3B type unsymmetrical 8,11,15,18,22,25-hexadecyl-2,3-(9,10-dioctyl-6,7-dimethoxy-2,3-dioxytriptycene) (11) and 8,11,15,18,22,25-hexadecyl-2,3-(9,10-diundecyl-6,7-dimethoxy-2,3-dioxytriptycene) (12) zinc(II) phthalocyanines were synthesized for the first time. Their photophysical and photochemical properties were investigated as solutions in toluene and obtained values were compared with unsubstituted zinc(II) phthalocyanine for determination of substitution effect. Both newly synthesized phthalocyanines showed high singlet oxygen generation making them good candidates as photosensitizers for photocatalytic reactions.
