“…A similar sorption behavior with broad isotherms and steep desorption steps at low pressures was frequently observed for H 2 and CH 4 adsorption in IFP MOFs [45][46][47][48] and in supramolecular hydrogen-bonded imidazolate frameworks (HIFs) [49,50] with gate effects (IFP = imidazolate framework Potsdam), in part also for CO 2 adsorption in IFPs [47,51]. Such a broad desorption behavior is rarely observed in microporous MOFs and only observed for MOFs with flexible substituents.…”

New metal-organic frameworks (MOF) with lanthanum(III), cerium(III), neodymium(III), europium(III), gadolinium(III), dysprosium(III), and holmium(III)] and the ligand precursor 1,3,5-tris(4-carboxyphenyl)-2,4,6-trimethylbenzene (H3L) were synthesized under solvothermal conditions. Single crystal x-ray analysis confirmed the formation of three-dimensional frameworks of [LnL(H2O)2]n·xDMF·yH2O for Ln = La, Ce, and Nd. From the nitrogen sorption experiments, the compounds showed permanent porosity with Brunauer-Emmett-Teller (BET) surface areas of about 400 m2/g, and thermal stability up to 500 °C. Further investigations showed that these Ln-MOFs exhibit catalytic activity, paving the way for potential applications within the field of catalysis.

“…For instance, though two kinds of sites exist in HMAC (4‐imidazolecarboxylic acid) and BIPYMO (a derivative of 4,4’‐bipyridine), the low‐dimensional metallotectons they formed finally lead to the dense‐stacking structures [83] . The bulk tetradecanuclear molecular building block with large steric also leads to the formation of the hydrogen‐bonded supramolecular metal‐imidazolate framework (HIFs) with low porosity and narrow channels [84] . More importantly, even if molecules possess two kinds of sites, not many extra functional sites would be left for functionalizing the hybrid HOFs, and their applications are significantly limited.…”

As a new class of porous crystalline materials, hydrogen-bonded organic frameworks (HOFs) assembled from building blocks by hydrogen bonds have gained increasing attention. HOFs benefit from advantages including mild synthesis, easy purification, and good recyclability. However, some HOFs transform into unstable frameworks after desolvation, which hinders their further applications. Nowadays, the main challenges of developing HOFs lie in stability improvement, porosity establishment, and functionalization. Recently, more and more stable and permanently porous HOFs have been reported. Of all these design strategies, stronger charge-assisted hydrogen bonds and coordination bonds have been proven to be effective for developing stable, porous, and functional solids called hybrid HOFs, including ionic and metallized HOFs. This Review discusses the rational design synthesis principles of hybrid HOFs and their cutting-edge applications in selective inclusion, proton conduction, gas separation, catalysis and so forth.

A series of neutral mononuclear lanthanide complexes [Ln(HL)2(NO3)3] (Ln = La, Ce, Nd, Eu, Gd, Dy, Ho) with rigid bidentate ligand, HL (4′-(1H-imidazol-1-yl)biphenyl-4-carboxylic acid) were synthesized under solvothermal conditions. The coordination compounds have been characterized by infrared spectroscopy, thermogravimetry, powder X-ray diffraction and elemental analysis. According to X-ray diffraction, all the complexes are a series of isostructural compounds crystallized in the P2/n monoclinic space group. Additionally, solid-state luminescence measurements of all complexes show that [Eu(HL)2(NO3)3] complex displays the characteristic emission peaks of Eu(III) ion at 593, 597, 615, and 651 nm.
