Expanding the Porphycene Core: Modification and Metalation

Abstract

Porphycenes, the first structural isomer of porphyrin, display unique chemical and photophysical properties. In this Account, we detail our group’s individual and collaborative efforts in elucidating further the chemical properties of porphycene. Particular emphasis will be placed on recent efforts devoted to expanding the porphycene core.1 Introduction2 Exploring the Chemistry of Porphycene3 Synthesis and Metalation of an Expanded Porphycene4 Conclusion

Pyrrolylmethylene Appended Corrorin: Peripheral Coordination and Transformation to Pyridyl Incorporated Hemiporphycene Analogue

“…In this respect, porphyrin isomers have been synthesized by changing the linking modes between the pyrrolic units. For example, porphycenes and hemiporphycenes have been synthesized by linking all or part of the pyrrolic moieties with ethylenyl moieties. In addition, N-confused porphyrins (NCP) can be synthesized by linking one of the pyrrole rings at the α,β′ positions (Figure a) .…”
