3,6,13,16-Tetrasubstituted Porphycene: The Missing Link in Porphycene Chemistry

Abstract

We have introduced the first 3,6,13,16-tetrasubstituted porphycene as its tetramethoxy analogue. This substitution pattern is one of the most general patterns yet missing in this isomeric porphyrin chemistry. This porphycene exhibits intense fluorescence along with the ability to coordinate with divalent metal ions; in particular, it forms the first stable Zn(II) complex among the tetrasubstituted porphycenes. Notably, the molecular structure of Zn1Py displays supramolecular chirality.
