As a robust and large molecular receptor, a kinetically‐locked trinuclear Co(III) macrocycle was synthesized with bis(β‐diketone) ligands having large π‐panels of 9,10‐diphenylanthracene moieties via a combination of Co(II)‐assisted self‐assembly and subsequent oxidation of the metal centers. The X‐ray structure revealed that the macrocycle had a discrete nanocavity of more than 300 Å3, which was surrounded by three anthracenyl panels in the middle. As the macrocycle has three cationic centres on each metal ion and a large cavity, it acts as a guest receptor for sodium tetraphenylborate. The binding constant was estimated to be 4.0×10−2M−1from1H NMR titration experiments, whereas no interaction was observed between the macrocycle and potassium 1‐adamantanecarboxylate.
