Abstract

This communication describes the transformation of a non-emissive heterocycle into a luminophore via modulation of molecular orbitals by employing a dialkylamine-substituted pentaazaphenalene (A5AP) skeleton. It was presumed that the introduction of the amine group changed the symmetry-forbidden HOMO–LUMO (H–L) transition to an allowed one. According to optical measurements and theoretical calculations, the H–L transition was turned into the symmetry-allowed one because of the lone pair on the nitrogen atom in the dialkylamine substituent. Finally, the A5AP derivatives presented significant emission from the H–L transition.
