The cover picture shows a supramolecular host that encapsulates unsubstituted pentacene. Pentacene has attracted much attention as an organic electric material, but it often suffers from its very low solubility. The self-assembled rectangular host shown in the picture has two pairs of terpyridine–platinum(II) moieties aligned parallel to each other and connected by diyne linkers. The host encapsulates the unsubstituted pentacene with a remarkably strong binding constant, and solubilizes it in acetonitrile up to the millimolar level. For the smaller acenes (naphthalene to tetracene), a planar arrangement of two molecules inside the cavity is achieved. Details are discussed in the article by T. Nabeshima et al. on p. 1678 ff.
