Relationship between the corrole macrocycle peripheral substitution type and character of its nonplanar distortions

, 2020
The analysis of the character of tetrapyrrolic macrocycle nonplanar distortions of free base corroles has been carried out. The molecular conformations of the corrole NH tautomers have been obtained with the quantum-chemical calculations (5,10-mesityl ...

Substituent‐Driven Anion‐Binding Selectivity in Aliphatic Chain‐Substituted 1,2‐Phenylene Urea Macrocycles and Optimized Synthetic Methodology

ChemistryOpen
1,2‐Phenylene tetraurea macrocycles recently attracted attention as self‐assembled channel‐making compounds with high selectivity to chlorides. Here, we report on the introduction of aliphatic chains in the periphery of the 1,2‐phenylene tetraurea ...
