Abstract
Strong electron donor–acceptor (EDA) association between carbazolo[3,4‐c]carbazoles and an optically active tetranitrofluorenone derivative was detected by UV–visible spectroscopy and by ^1^H NMR shifts. ^1^H NMR splittings at low temperatures are due to diastereomeric association complexes and, thus, prove the chirality of carbazolocarbazoles.
