Host−Guest Interactions of 4-Carboxyphenoxy Phthalocyanines and β-Cyclodextrins in Aqueous Media

β-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.
