Abstract
The title pull–push chromophores, 2-[4-(dimethylamino)benzylidene]-1H-indene-1,3(2H)-dione (ID[1]) and (E)-2-{3-[4-(dimethylamino)phenyl]allylidene}-1H-indene-1,3(2H)-dione (ID[2]), with donor–π-bridge–acceptor structures, are almost planar for the molecule with a short π-bridge (ID[1]) but less planar for the molecule with a longer bridge (ID[2]).
