Cucurbit[8]uril Binding In their Communication on page 225 ff., J. Fraser Stoddart and co‐workers show that the dimethyldiazaperopyrenium dication, prepared in three steps from a pigment used in car paint, behaves as both a viologen‐like electron‐poor and an electron‐rich guest, resulting in the formation of a 1:2 complex with cucurbit[8]uril. The inside cover image, produced by Aleksandr Bosoy, illustrates that, upon formation of this 1:2 complex, an increase in the fluorescence quantum yield occurs compared to that observed for the dication on its own.
