[5]Helicene-Fused Phthalocyanine Derivatives. New Members of the Phthalocyanine Family
摘要:
An efficient synthetic route to fuse [5]helicene moieties around the plithalocyanine core is reported. The helicene moiety was constructed by the Diels-Alder reaction of 3,4,3',4'-tetrahydro-1,1'-dinaphthyI and dibromobenzyne. Subsequent cyanation, oxidation, O-alkylation, and cyclic tetramerization resulted in octaalkoxy plithalocyanine derivatives which showed high solubility in common organic solvents and displayed strong absorption in the near-IR region.
