Synthesis and Characterization of New Cross-like Porphyrin-Naphthalocyanine and Porphyrin-Phthalocyanine Pentads

Synthesis and characterization of new cross‐like porphyrin–naphthalocyanine and porphyrin–phthalocyanine systems, where one naphthalocyanine and one phthalocyanine are the central moieties of the pentads, respectively, and in both cases substituted with four porphyrin units, in a cross‐shape structu...

Description
Summary:Synthesis and characterization of new cross‐like porphyrin–naphthalocyanine and porphyrin–phthalocyanine systems, where one naphthalocyanine and one phthalocyanine are the central moieties of the pentads, respectively, and in both cases substituted with four porphyrin units, in a cross‐shape structure. Porphyrin–naphthalonitrile and porphyrin–phthalonitrile adducts were prepared from the reaction of 5‐(p‐hydroxyphenyl)‐10,15,20‐triphenylporphyrin with the appropriate dihalogenated naphthalonitrile or phthalonitrile, respectively, to provide a straightforward cyclotetramerization in the presence of metallic magnesium, used as template. Spectroscopic characterization and initial photophysical assessment are also reported.
