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 focuses on the postfunctionalization of porphyrins and related compounds
through catalytic and stoichiometric organometallic methodologies. The employment of …

Free radicals were generally regarded as highly reactive, transient and harmful species. In
fact, some of the free radicals can also be inactive, long-lived and beneficial for our health …

Organic radicals can potentially play important roles in functional materials owing to an
unpaired electron, but they are usually highly reactive and difficult to use. Therefore …

The non-innocent ligand nature of porphyrins was observed for compound I in enzymatic
cycles of cytochrome P450. Such porphyrin radicals were first regarded as reactive …

Reversible homolytic dissociation of the bis (pyrimidinenorcorrole) σ‐dimer was elucidated
by means of variable temperature ESR and 1H NMR spectroscopy, mass spectrometry, and …

π-Conjugated molecules with an even number of π-electrons usually have a closed-shell
ground state. However, recent studies have demonstrated that a certain type of molecules …

Persistent organic radicals have gained considerable attention in the fields of catalysis and
materials science. In particular, helical molecules are of great interest for the development …

Stable helical radicals are promising multi‐functional molecules in light of intriguing
magnetic and chiroptical properties. Attempts were made to extend diphenylmethyl‐fused …

Abstract A benzene‐1, 3, 5‐triaminyl radical fused with three ZnII‐porphyrins was
synthesized through a three‐fold oxidative fusion reaction of 1, 3, 5‐tris (ZnII …
