A circular dichroism (CD) exciton chirality method based on a host-guest chiral recognition has allowed the absolute configuration of 10,20-bis(3',5'di-tert-butyl-phenyl-13-acetyl-3-(hydroxyethyl)porphyrin, a self building light harvesting porphyrin. Computational studies have provide a strong theoreotical basis for the assignment.
