This review underscores the conformational flexibility of porphyrinoids, a unique class of
functional molecules, starting from the smallest triphyrins (1.1. 1) via [18] porphyrins (1.1 …

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 …

A nanographene-fused expanded carbaporphyrin (5) and its BF2 complex (6) were
synthesized. Single-crystal X-ray structures revealed that 5 and 6 are connected by two hexa …

Benziporphyrins were first discovered over 20 years ago. Although initially they were
considered to be a chemical curiosity, a wide range of benzene-containing porphyrinoid …

Two belt-like expanded carbaporphyrins (NB1 and NB2) were prepared via a one-pot
procedure that involves a [6+ 3] condensation between a pyrene-bearing tetrapyrrole …

The cavities of carbaporphyrinoid systems provide unique environments for the formation of
organometallic species. These systems commonly act as either dianionic or trianionic …

This Review outlines the progress in the field of synthetic expanded carbaporphyrinoids.
The evolution of this topic is demonstrated with expanded porphyrin‐inspired systems with a …

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