Abstract

The novel mono-, di-, tri-, and pentacarbazolyl-substituted flavones were obtained from 2',3',4',5',6'-pentafluoroflavone and carbazole by varying the conditions of the base-promoted nucleophilic aromatic substitution reaction. The spatial structure of products in crystals was explored using X-ray diffraction analysis. The synthesized mono- and pentacarbazolyl-substituted derivatives showed satisfactory luminescent properties with photoluminescence quantum yield up to 0.42.
