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 …

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 …

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

The chemistry of expanded porphyrins, which are higher homologues of porphyrins, has
been intensively explored for the last three decades. Expanded porphyrins exhibit …

Expanded porphyrins are synthetic analogues of the porphyrins, and differ from these and
other naturally occurring tetrapyrrolic macrocycles by containing a larger central core with a …

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 aromatic character of porphyrins, which has significant chemical and biological
consequences, can be substantially altered by judicious modifications of the parent ring …

Woodward and his colleagues1, 2 were the first to report the probable existence of an
expanded porphyrin, a pentapyrrolic sapphyrin (1), and but for the beautiful blue crystals that …

Sapphyrin was the first expanded porphyrin to be reported in the literature and remains
among the most extensively studied. Much of the interest in this macrocycle reflects its ability …

In recent years expanded porphyrins have emerged as a promising class of molecules in
light of their optical, electrochemical, and coordination properties. 1 Continuing synthetic …
