Dual Emission of a Free‐Base 5‐Oxaporphyrinium Cation from its<i>cis</i>‐ and<i>trans</i>‐NH Tautomers
Replacement of the meso methine carbon atoms of porphyrins with heteroatoms is a powerful strategy for tuning their optical and electronic properties. In particular, 5‐oxaporphyrin is an attractive target due to its importance as an intermediate in heme catabolism. In this work, we describe the synthesis and properties of a free‐base 5‐oxaporphyrinium cation, which was prepared by the ring‐closure
