TLDR
In this paper, pyrene-fused porphyrins via the oxidative intramolecular ring closure reactions of meso-pyrenylporphyrin were prepared.Abstract:
We prepared novel pyrene-fused porphyrins via the oxidative intramolecular ring closure reactions of meso-pyrenylporphyrin. The excitation energies and the oxidation potentials of the isolated dark...read more

Comparison of Oxidative Aromatic Coupling and the Scholl Reaction
TL;DR: The authors venture the hypothesis that, depending on the electronic structure of the substrates and the nature of the "catalyst", two different mechanisms can operate, one involves the intermediacy of a radical cation and the other the formation of a sigma complex between the acid and the substrate.

A Porphyrin Fused to Four Anthracenes
TL;DR: A fused tetraanthracenylporphyrin is synthesized by oxidation of a meso-anthracENyl nickel(II) porphyrin with FeCl(3), which exhibits an intense red-shifted absorption spectrum.

Fully conjugated porphyrin tapes with electronic absorption bands that reach into infrared.
Akihiko Tsuda,Atsuhiro Osuka +1 more
TL;DR: The lowest electronic absorption bands become increasingly intensified and red-shifted upon the increase in the number of porphyrins and eventually reach a peak electronic excitation for the dodecamer at ∼3500 wavenumber.

Syntheses, structural characterizations, and optical and electrochemical properties of directly fused diporphyrins.
TL;DR: Directly fused diporphyrins display the extensive pi conjugation as evinced by highly perturbed electronic absorption spectra as well as lowered and largely split first oxidation potentials.

Doubly meso‐β‐Linked Diporphyrins from Oxidation of 5,10,15‐Triaryl‐Substituted NiII– and PdII – Porphyrins
TL;DR: In this paper, lower oxidation potentials than for the monomeric starting materials are displayed by diporphyrins obtained by one-electron oxidation with tris(4-bromophenyl)ammonium hexachloroantimonate.
