Metal-hinged, organic-pillared cages accommodate a limited number (n) of π-stacked molecules in the cavity (see scheme): Discrete n + 2 aromatic stacking occurs by the accommodation of n large aromatic guests (n = 1-3). Owing to efficient donor-acceptor (D-A) interactions, A-D-A (n = 1), A-D-D-A (n = 2), and A-D-A-D-A (n = 3) stacks are observed, which bring about even-odd-number effects in the UV/Vis absorption spectra.
