The extension of the aromatic π-system of porphyrins is a powerful method to alter their optoelectronic properties. Herein, aryl substituents were fused to porphyrin cores by Scholl oxidation reactions that selectively produced mono- and doubly-fused porphyrins in yields of up to 69 %. Several different aryl substituents attached to the porphyrin were investigated with respect to their reactivity under Scholl conditions. The fused products were fully characterized, i.e., by UV/Vis absorption spectroscopy, which showed drastic changes in the electronic features. Insight into the solid-state behavior was obtained by X-ray crystallography. Our approach represents a novel option for the late-stage functionalization of porphyrin-based compounds.

Microwave assisted synthesis, metallation, and β -formylation of porphyrins is described. All synthetic reactions were carried out on inorganic polymer solid support using microwave energy. It is the first documented application of the Duff reaction in th

(Figure Presented) Bowled over: Calix[3]dipyrrins were synthesized from pyrrole and aryl aldehyde precursors by the Lindsey protocol, modified by the presence of a small amount of water. These bowl-shaped macrocycles can accommodate three metal (M) ions such as NiII and CuII in a hexagonal M3O3 manner (see structure; Cu green, N blue, O red, C black).
Thermal study of metalloporphyrin complexes with benzene

The crystal solvates of the complexes MP (P is the dianion of tetrakis(3,5-di-tert-butylphenyl)porphine, M = Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II)) and (Ac)MnP with benzene were obtained by isothermal evaporation of corresponding solutions at 35°C. Their thermal decomposition was studied. The compositions of the crystal solvates and the temperature and enthalpy of evaporation of benzene from them were determined. The π system of the macrocyclic ring in the metalloporphyrins was found to act as the π donor with respect to the aromatic system of the benzene molecule. Copyright
