The molecular structures of 10,10′-biacridinyl-9,9′-dione (5), 9-(10′-bromo-9′-anthryl)carbazole (9) and 9,9′-bicarbazyl (12) have been solved by X-ray crystallography. Proton and carbon-13 NMR studies of these and related compounds, show that in solution their conformations are also 'scissor-like'. AM1 semi-empirical calculations provide a rationale for the geometries of these compounds.
