The exquisite combination of independent 3p [In(CO₂)₄] units and 4f [Tb₂(CO₂)₈] clusters in the presence of the designed hexatopic 2,4,6-tri(2,4-dicarboxyphenyl)pyridine ligand engenders one peculiar nanocaged In(III){Tb(III)}₂-organic framework: ({(Me₂NH₂)[InTb₂(HTDP)₂]·3DMF·3H₂O}_n, designated as NUC-5), which features dual types of lotus-shaped channels along the [100] and [110] axes with related node windows of 5.3 × 6.8 and 12.1 × 9.2 Ų, resp. To the best of our knowledge, except several coexisted 3p-4f In/Ln clusters of {In₃Ln}- and {In₃Ln₂}-based metal-organic frameworks (MOFs), NUC-5 is one novel type of In/Ln heterometallic framework. In addition, its topol. was an unprecedented 3D TAYZIC net with a Schlafli symbol of {4.⁴6²}{4.⁵6⁵}₂{4.⁶6.⁸8}. Moreover, activated NUC-5 is proved to be one efficient adsorbent for CO₂ and one recycled cycloaddition catalyst for the transformation of epoxides into related carbonates with high yields under mild conditions. Furthermore, the excellent reversible sorption performance for I₂ in the volatilization phase or in cyclohexane solution with a maximum adsorption capacity of 609.1 mg/g (3.75 iodine mols. per unit cell) makes NUC-5 a promising adsorbent for radioactive products of ¹²⁹I and ¹³¹I in the field of nuclear industry. This study provides one synthetic strategy that the original nature of MOFs could be enhanced by introducing some specific function-prompted inorganic subunits with the aid of predesigned supporting ligands.

The exquisite combination of heterometallic [Tb^IIIMn^II(CO₂)₃(H₂O)₂] clusters with the hexacarboxylate ligand of H₆TDP generates one water-stable 3D heterometallic Tb^III/Mn^II-organic framework material {[TbMn(HTDP)(H₂O)₂]·5DMF·4H₂O}_n (NUC–3; H₆TDP = 2,4,6-tri(2′,4′-dicarboxyphenyl)pyridine), which consists of functionalized noninterspersed opening nanochannels shaped by six rows of [Tb^IIIMn^II(CO₂)₃(H₂O)₂] clusters. Based on the single-component sorption measurements, activated NUC–3 framework exhibits effective CO₂/CH₄ separation associated with high uptake and moderate adsorption enthalpy of CO₂. Dynamic breakthrough experiments reveal that NUC–3 could be competent for the separation of CO₂/CH₄ (50:50, v:v) mixture Moreover, the kinetic and equilibrium experiments of iodine adsorption indicate that NUC–3 possess excellent adsorption capacity for iodine mols. in cyclohexane solution The excellent structural stability and functional internal surface makes NUC–3 a prospective adsorbent for practical CO₂/CH₄ separation and adsorption elimination of iodine mols., opening up the insight of heterometallic MOFs for pratical application.

Creative assembly of bimetallic [Zn^IITb^III(CO₂)₃(H₂O)] clusters and the desigened bifunctional ligand of H₆TDP engendered one highly robust anionic heterometallic framework {[(CH₃)₂NH₂][Zn^IITb^III(TDP)(H₂O)]·3DMF·3H₂O}_n (NUC-7), which featured two types of nanochannels decorated with d. open metal sites and free oxygen atoms on the wall. To the best our knowledge, NUC-7 represented one novel kind of heterometallic Zn^II/Ln^III-organic 3D honeycomb MOFs with exposed tetra-coordinated Zn^II-metal sites as Lewis acid sites. Subsequent studies indicated that NUC-7 could highly adsorb CO₂ and catalyze the cycloaddition of various epoxides into related carbonates with the help of cocatalyst TBAB under lukewarm conditions of 1 atm and 80°C. Meanwhile, NUC-7 exhibited the effectively selective sensitivity for discriminating Fe³⁺ in aqueous solution by luminescence quenching. It could be inferred that the excellent characteristics including large void volume, high porosity, active open metal sites, and uncoordinated carboxylate oxygen atoms as Lewis acid and base sites rendered NUC-7 one ideal platform for gas reservoir, specific catalyst, and luminescence sensing.
