Novel π-Conjugated Systems Based on N-Confused Porphyrinoids

  • Chapter
Chemical Science of π-Electron Systems

Abstract

N-confused porphyrin (termed as NCP) is an isomer of porphyrin in which a pyrrole is connected to the neighboring meso-carbon atoms at α,β′-positions. The specific π-conjugated scaffold present in NCPs provides unique photophysical and electrochemical properties as well as abilities of metal complexation and anion binding in many cases. That has inspired us to explore the further synthetic approaches for development of novel class of porphyrin analogues based on “N-confusion concept.” This chapter introduces an overview of recent development in the chemistry of N-confused porphyrin and related macrocycles.
