Since the discovery of its facile synthesis in 2001, meso-aryl-substituted expanded
porphyrins have been developed as a new class of azaannulenes in light of their facile …

Recently, Baird (anti) aromaticity has been referred to as a description of excited-state (anti)
aromaticity. With the term of Baird's rule, recent studies have intensively verified that the …

The design of new molecules for photochemical studies typically requires knowledge of
spectral features of pertinent chromophores beginning with the absorption spectrum (λabs) …

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 …

Modification of aromaticity is regarded as one of the most interesting and important research
topics in the field of physical organic chemistry. Particularly, porphyrins and their analogues …

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] …

Despite the central role of aromaticity in the chemistry of expanded porphyrins, the
evaluation of aromaticity remains difficult for these extended macrocycles. The presence of …

We describe the synthesis and characterization of directly meso–meso linked porphyrin–[26]
hexaphyrin–porphyrin hybrid oligomers and their triply linked (completely fused) hybrid …

A singly linked corrole dimer was synthesized by condensation of a dipyrromethane‐1‐
carbinol with 1, 1, 2, 2‐tetrapyrroethane. Oxidation of the dimer gave doubly linked corrole …

We have demonstrated aromaticity reversal in the singlet excited states of internally 1, 3-
phenylene-strapped [26]-and [28] hexaphyrins (P26H and P28H). P26H displays a broad …
