Synthesis and Photophysical Properties of Porphyrin Macrorings Composed of Free-Base Porphyrins and Slipped-Cofacial Zinc Porphyrin Dimers

Synthesis and Photophysical Properties of Porphyrin Macrorings Composed of Free-Base Porphyrins and Slipped-Cofacial Zinc Porphyrin Dimers
Yusuke Kuramochi, Akiharu Satake, Yuki Kawakami
The covalently linked self-assembled macroring C-(Zn-Fb-Zn)3 with the complementary coordination from the imidazolyl groups to the zinc ions was composed of three slipped-cofacial zinc porphyrin dimers (“special pair model”) and three free-base porphyrins alternately. The fluorescence spectrum and the electrochemical measurements of C-(Zn-Fb-Zn)3 showed the photoinduced electron transfer from the zinc porphyrin dimer to the free-base porphyrin when polar solvent was used. C-(Zn-Fb-Zn)3 could be a good precursor to construct various heteromultinuclear porphyrin macrorings.
