The pyrene-terpyridine-pyrene-based receptor 1 converts from a W to a U shape upon ion-metal cation complexation. The U form of 1 is capable of substrate binding through insertion between the lateral donor-pyrene arms of acceptor-terpyridine-type systems, with the participation of the metal ions, simultaneously coordinating the binding units of such multicomponent dynamic devices.
