Confusion is a novel concept of isomerism in porphyrin chemistry, delivering a steady
stream of new chemistry since the discovery of N-confused porphyrin, a porphyrin mutant, in …

Cyclometalation refers to the transition metal-mediated activation of a CR bond to form a
metallacycle comprising a new metal-carbon σ bond (Scheme 1). 1, 2 Typically, the reaction …

The replacement of one or more pyrrolic building block (s) of a porphyrin by a nonpyrrolic
heterocycle leads to the formation of so-called pyrrole-modified porphyrins (PMPs) …

The world of modified porphyrins changed forever when an N-confused porphyrin (NCP), a
porphyrin isomer, was first published in 1994. The replacement of one inner nitrogen with a …

Following immediately after the serendipitous discovery of N-confused porphyrins,
remarkably diverse carbaporphyrinoid systems have been synthesized and investigated. By …

This article introduces an overview of progressively developing chemistry of N-confused
porphyrin and related macrocycles. Study on confusion results in discovery of fusion and …

N-confused porphyrin (NCP) is a porphyrin isomer that is different largely from the parent
porphyrin, particularly in the physical, chemical, structural, and coordination properties …

An alteration of a metalloporphyrin coordination core, exemplified by 21-heteroporphyrins
and 2-aza-21-carbaporphyrin (N-confused porphyrin, inverted porphyrin), provides a route …

A doubly N-confused porphyrin (N2CP), 2-ethoxy-5, 10, 15, 20-tetrapentafluorophenyl-3, 7-
diaza-21, 22-dicarbaporphyrin, and its Ag (III) and Cu (III) complexes were synthesized for …

Using regular nonlocal density functional theory (DFT) as well as combined DFT and
configuration interaction calculations, we have carried out a first theoretical study of the …
