This review surveys recent progress in the chemistry of polycyclic heteroaromatic molecules
with a focus on structural diversity and synthetic methodology. The article covers literature …

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 …

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

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 …

Porphyrins and expanded porphyrins have attracted the attention of chemists for a long time
in view of their diverse applications in catalysis; as anion, cation, and neutral substrate …

Compared to porphyrin, its isomeric, expanded, and contracted analogues are less well
explored. This contrast is found to be even more drastic in the case of their peripherally …

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 …

A fully conjugated three-dimensional (3D) expanded carbaporphyrin (2) was prepared in a
one-pot procedure that involves a [2+ 4] condensation reaction between a dibenzo [g, p] …

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 …

Stable and nonaromatic phenothiazinophyrins which resulted from the replacement of one
of the pyrrole rings of porphyrin with a phenothiazine unit were synthesized by condensing …
