Supramolecular chirogenesis in bis-porphyrins: interaction with chiral acids and application for the absolute configuration assignment

[structure: see text] A new supramolecular chirogenic system on the basis of bis(free base porphyrin) and various enantiopure acids, which can be effectively applied for the chirality sensing purposes, is reported. The temperature and solvent are found to be key factors controlling the chirality transfer process in these assemblies.
