Highly selective synthesis and near-infrared photothermal conversion of metalla-Borromean ring and [2]catenane assemblies.

ABSTRACT: Although the selective synthesis of complicated supramolecular architectures has seen significant progress in recent years, the exploration of the properties of these complexes remains a fascinating challenge. Herein, a series of new supramolecular topologies, metalla[2]catenanes and Borromean ring assemblies, were constructed based on appropriate Cp*Rh building blocks and two rigid alkynyl pyridine ligands (L1, L2) via coordination-driven self-assembly. Interestingly, minor differences between the two rigid alkynyl pyridine ligands with/without organic substituents led to products with dramatically different topologies. Careful structural analysis showed that π-π stacking interactions play a crucial role in stabilizing these [2]catenanes and Borromean ring assemblies, while also pr
