Metal-organic frameworks (MOFs) are hybrid organic/inorganic structures with well-defined topologies which feature metal ions or clusters bridged by rigid organic linkers and have attracted immense interest for their catalytic, sensing, magnetic and adsorption properties among others. Their high porosity (surface areas of up to 7000 m2/g) can be exploited to encapsulate a wide variety of guest molecules and numerous possibilities for tunable characteristics arise from careful manipulation of both the organic and inorganic components. One of the crystal engineering approaches of MOFs is reticular synthesis and enables rational design and assembly of novel porous materials by utilizing building blocks with varying structures and functionalities to attain certain desired physical and chemical properties. However, reticular synthesis using lanthanide metals ions as building blocks is disinclined due to their high coordination numbers and unpredictable coordination chemistry. Herein, a new approach to the crystal engineering of Ln-MOFs, their ratiometric tunable luminescence properties and ability to sense metal ions and components of nitroaromatic explosives is presented.
