Acid catalysed Friedländer cyclization of 2-aminobenzophenones with 1,2-, 1,3-, and 1,4-cyclohexadiones, followed by aromatization, has been used to prepare dibenzophenanthrolines (DBPs) containing 1,10-, 1,7- and 4,7-phenanthroline units, whose optoelectronic properties have been compared. The LUMO...
