Synthesis and Aggregation Studies of Functional Binaphthyl-Bridged Chiral Phthalocyanines.

We describe the preparation of a battery of chiral Zn(II) phthalocyanines with an AABB substitution pattern through cross-condensation of different chiral, binaphthyloxy-linked bisphthalonitriles and (non)functionalized single phthalonitriles. All the compounds are endowed with reactive groups (halogen and/or ethynyl moieties) that will allow us to prepare customized amphiphilic phthalocyanines. Preliminary self-assembly studies in solution have been performed by UV-vis and circular dichroism experiments.
