Host-guest interactions of 4-carboxyphenoxy phthalocyanines and beta-cyclodextrins in aqueous media.
Beta-cyclodextrin and its permethylated derivatives form 2:1 inclusion complexes with tetrakis- and octakis(4-carboxyphenoxy)phthalocyanines 1-4, reducing their aggregation tendency and promoting their sensitization of singlet oxygen formation in aqueous media.
