Two-dimensional (2D) materials with higher order in-plane nanoscale pores play a crucial role in innumerable applications, but their precise and reasonable preparation remains huge challenge. Herein, we report the highly robust 2D dysprosium(III)–organic framework {[Dy(H2BDTP)(DMF)2]·2DMF·3H2O}n (NUC-101) (15.2 × 6.4 Å2) (H5BDTP = 2,6-bis(2,4-dicarboxyphenyl)-4-(2H-tetrazol-5-yl)pyridine). After activation, scarcely reported host [Dy2(H2BDTP)2]n is of great interest due to that it not only contains voids 15.2 11.7 Å3 also functionalized by free carboxyl, pyridinyl, tetrazolyl groups upper lower parts.

Adjusting the Lewis acid–base sites in MOF-based catalysts to meet demand for catalytic CO2 chemical fixation is a huge challenge. Herein, highly robust rectilinear {Zn3}-based metal–organic framework of {[Zn3(TNTNB)2(4,4′-bip)(H2O)2]·5DMF·9H2O}n (NUC-80) was generalized from solvothermal condition (H3TNTNB = 1,3,5-tri(3-nitro-4-carboxyphenyl)-2,4,6-trinitrobenzene, 4,4′-bip 4,4′-bipyridine). Activated NUC-80a not only owns large void volume (58%) and two kinds solvent-accessible channels: rhombic-like (ca. 14.24 × 14.57 Å) along axis rectangular-like 11.72 14.48 b axis, but also functionalized by rich metal plentiful nitro groups on its inner surface. Performed experiments confirmed that could efficiently catalyze cycloaddition reaction with epoxides Knoevenagel condensations aldehydes malononitrile under mild conditions high turnover frequency (TOF). Hence, this work provides nitro-functionalized cluster-based nanoporous wide range potential applications such as catalysis, gas adsorption, separation.

Developing a highly active catalyst that can efficiently capture and convert carbon dioxide (CO2) into high-value-added energy materials remains severe challenge, which inspires us to explore effective metal–organic frameworks (MOFs) with high chemical stability high-density sites.
