Binary nanocrystal superlattices present unique opportunities to create novel interconnected nanostructures by partial fusion of specific components the superlattice. Here, we demonstrate binary AB6 superlattice PbSe and Fe2O3 nanocrystals as a model system transform central hexamer into single fused particle. We detailed structural analysis combining high-resolution X-ray scattering electron microscopy. Molecular dynamics simulations show optimum separation in agreement with experiment provide insights molecular configuration surface ligands. describe concept versatile 'nanoreactor' study materials based on precisely defined size, composition structure mesostructured cluster. 'controlled fusion' clusters reactions initiated thermal treatment pulsed laser annealing.
