文摘

Bottom-up fabrication of complex 3D hollow superstructures from nonspherical building blocks (BBs) poses a significant challenge for scientists in materials chemistry and physics. Spherical colloidal silica or polystyrene particles are therefore often integrated as BBs for the preparation of an emerging class of materials, namely colloidosomes (using colloidal particles for Pickering stabilization and fusing them to form a permeable shell). Herein, we describe for the first time a one-step emulsion-based technique that permits the assembly of metal鈥搊rganic framework (MOF) faceted polyhedral BBs (i.e., cubes instead of spheres) into 3D hollow superstructures (or 鈥渃olloidosomes鈥?. The shell of each resultant hollow MOF colloidosome is constructed from a monolayer of cubic BBs, whose dimensions can be precisely controlled by varying the amount of emulsifier used in the synthesis.
