We have constructed an unprecedented MOF platform that accommodates a range of 5f-block metal ions (Th4+, U4+, Np4+, Pu4+) as the primary building block. The isoreticular actinide metal-organic frameworks (An-MOFs) exhibit periodic trends in 12-coordinate environment, ligand configuration, and resulting ultramicroporosity. It holds potential distinguishing neighboring tetravalent actinides. ionic radius, carboxylate bite angle, anthracene plane twisting, interligand interactions, countercation templating collectively determine interplay between solvation, modulation, complexation, coordination saturation central actinide, while lanthanide counterparts are stabilized by formation dimer-based motif. Quantum chemical calculations indicate this large number is only feasible high-symmetry environment provided An-MOFs. This category MOFs not demonstrates autoluminescence (4.16 × 104 counts per second gram) but also portends wide-bandgap (2.84 eV) semiconducting property with implications for multitude applications such hard radiation detection.
