Mono-meso-free N-confused Hexaphyrin with Tunable NIR Absorption: Synthesis, Coordination, and Oxidative Dimerization
Abstract
A weakly Möbius aromatic mono-meso-free N-confused hexaphyrin 1 was synthesized and oxidized into a Cmeso-Cmeso linked dimer (1)2. Interestingly, metallation of 1 with Cu(II) in MeCN/MeOH afforded not only 1-Cu but also three complexes of ligands generated in-situ by oxygenation and methoxylation of 1 at meso-and α- positions.
