Abstract: Tetraphenylporphyriyne (Pyne1), a novel porphyrin analogue with a C≡C bond incorporated into an 18-π-conjugated system, has been created via cleavage of the N-confused pyrrolic ring in Ag(III) N-confused tetraphenylporphyrin. The structure of Pyne1 was confirmed… read more here.

DOI: 10.1021/jacs.1c13478
Abstract: Several fully π-conjugated macrocycles with puckered or cage-type structures were recently found to exhibit aromatic character according to both experiments and computations. We examine their electronic structures and put them in relation to 3D-aromatic molecules… read more here.

Abstract: A new group of aromatic porphyrinoids was obtained by an oxidative insertion of primary amines into the antiaromatic ring of 5,14-dimesityl-norcorrolatonickel(II) activated by iodosobenzene. The substituted 10-azacorroles thus formed were characterized by spectroscopic and electrochemical… read more here.

DOI: 10.1039/d3qo00487b
Abstract: Two o-carborane-based π-conjugated macrocycles are synthesized via oxidative coupling of acetylene-terminated o-carborane precursors. The single-crystal X-ray diffraction analysis unambiguously revealed their unique porous supramolecular structures, which display micropore characteristics. The... read more here.
