Abstract Three-dimensional superlattices consisting of nanoparticles represent a new class condensed materials with collective properties arising from coupling interactions between close-packed nanoparticles. Despite recent advances in self-assembly nanoparticle superlattices, the constituent have been limited to those that are attainable as monodisperse In addition, self-assembled generally weakly coupled due surface-coating ligands. Here we report fabrication three-dimensionally interconnected face-centered cubic symmetry without presynthesis We show mesoporous carbon frameworks derived supercrystals can be used robust matrix for growth diverse compositions. The resulting embedded particularly suitable energy storage applications. demonstrate this by incorporating tin oxide anode lithium-ion batteries, and electrochemical performance is attributable their unique architectures.
