A trimethylamine (TEA)-assisted synthesis approach that combines the preparation of hierarchical porous ZIF-8 nanoparticles and one-pot encapsulation of target molecules is presented. The in situ formation of ZnO nanocrystals promoted by TEA leads to simple, fast, and scalable synthesis of hierarchical porous RhB@ZIF-8 (RhB: rhodamine B). The dye molecules encapsulated in the ZIF-8 nanoparticles show improved photophysical properties. The method can be extended for encapsulation of proteins and for synthesis of Co-based zeolitic imidazolate frameworks (ZIFs).
