Abstract
| - An efficient synthetic route to fuse [5]helicenemoieties around the phthalocyanine core is reported. Thehelicene moiety was constructed by the Diels−Alder reactionof 3,4,3‘,4‘-tetrahydro-1,1‘-dinaphthyl and dibromobenzyne.Subsequent cyanation, oxidation, O-alkylation, and cyclictetramerization resulted in octaalkoxy phthalocyanine derivatives which showed high solubility in common organicsolvents and displayed strong absorption in the near-IRregion.
