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 …

Core alteration, affording heteroporphyrinoids and carbaporphyrinoids, allows for the
exploration of porphyrin-like or porphyrin-unlike coordination chemistry. Such a strategy has …

The Cambridge Structural Database (CSD) is a collection of over one million experimental
three-dimensional structures obtained through crystallographic analyses. These structures …

An adj‐dicarbacorrole with CCNN in the core is achieved by replacing the bipyrrole moiety
by a simple polycyclic aromatic hydrocarbon, such as biphenyl unit. Spectroscopic studies …

Two cyclic carbaporphyrin arrays (trimer 6 and tetramer 7) were synthesized from a
dibrominated carbaporphyrin precursor (5) via a one-pot Yamamoto-type coupling. Single …

The incorporation of a phenanthrene moiety into a porphyrin framework results in the
formation of a hybrid macrocycle—phenanthriporphyrin—merging the structural features of …

Bis-dicarbacorrole (bis-H 3) with two adj-CCNN subunits was synthesized by incorporating a
dibenzo [g, p] chrysene moiety into the macrocyclic structure. The two trianionic cores in bis …

In 1960, MacDonald and coworkers introduced a new method for porphyrin synthesis that
involved the acid-catalyzed condensation of dipyrrylmethane dialdehydes with α, α …
