By taking advantage of self‐complementary π–π stacking and CH–π interactions, a series of discrete quadruple stacks were constructed through the self‐aggregation of U‐shaped dirhodium metallotweezer complexes featuring various planar polyaromatic ligands. By altering the conjugate stacking strength and bridging ligands, assemblies with a range of topologies were obtained, including a binuclear D‐shaped macrocycle, tetranuclear open‐ended cagelike frameworks, and duplex metallotweezer stacking structures. Furthermore, a rare stacking interaction resulting in selective C−H activation was observed during the self‐assembly process of these elaborate architectures.
