Homochiral Emissive Lambda(8)- and Delta(8)-[Ir8Pd4](16+) Supramolecular Cages

Résumé

Synthetic self-assembly is a powerful technique for the bottom-up construction of discrete and well-defined polyhedral nanostructures resembling the spherical shape of large biological systems. In recent years, numerous Archimedean-shaped coordination cages have been reported based on the assembly of bent monodentate organic ligands containing two or more distal pyridyl rings and square-planar PdII ions. The formation of photoactive Pd-II metallamacrocycles and cages, however, remain rare. Here we report the first examples of emissive and homochiral supramolecular cages of the form [(IrPd4)-Pd-8](16+). These cages provide a suitably sized cavity to host large guest molecules. Importantly, encapsulation and energy transfer have been observed between the blue-emitting NBu4[Ir(dFppy)(2)(CN)(2)] guest and the red-emitting Delta(8)-[Ir8Pd4](16+) cage.
