Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Two porous metal–organic frameworks (MOFs), [Zn₃(L)(H₂O)₂]<bold>⋅</bold>3 DMF<bold>⋅</bold>7 H₂O (<bold>MOF‐1</bold>) and [(CH₃)₂NH₂]₆[Ni₃(L)₂(H₂O)₆]<bold>⋅</bold>3 DMF<bold>⋅</bold>15 H₂O (<bold>MOF‐2</bold>), were synthesized solvothermally (H₆L=1, 2, 3, 4, 5, 6‐hexakis(3‐carboxyphenyloxymethylene)benzene). In <bold>MOF</bold>‐<bold>1</bold>, neighboring Zn^II trimers are linked by the backbones of L ligands to form a fascinating 3D six‐connected framework with the point symbol (4¹².6³) (4¹².6³). In <bold>MOF‐2</bold>, eight L ligands bridge six Ni^II atoms to generate a rhombic‐dodecahedral [Ni₆L₈] cage. Each cage is surrounded by eight adjacent ones through sharing of carboxylate groups to yield an unusual 3D porous framework. Encapsulation of Ln^III cations for tunable luminescence and small drug molecules for efficient delivery were investigated in detail for <bold>MOF‐1</bold>.</p> </abstract>
