“…7 F 1 , which implies that the Eu III cations in these complexes are located in lower symmetry coordination environments. The luminescence quantum yields of CP5 were determined to be 22% and the quantum yield of CP5 is slightly greater than for some Eu compounds reported previously (Abdelhamid et al, 2019;Liao et al, 2019).…”

Six two-dimensional (2D) coordination polymers (CPs), namely, poly[{μ5-3,3-[(5-carboxylato-1,3-phenylene)bis(oxy)]dibenzoato-κ6 O 1:O 1′:O 3,O 3′:O 5:O 5′}bis(N,N-dimethylformamide-κO)lanthanide(III)], [Ln(C21H11O8)(C3H7NO)2] n , with lanthanide/Ln = cerium/Ce for CP1, praseodymium/Pr for CP2, neodymium/Nd for CP3, samarium/Sm for CP4, europium/Eu for CP5 and gadolinium/Gd for CP6, have been prepared by solvothermal methods using the ligand 3,3′-[(5-carboxy-1,3-phenylene)bis(oxy)]dibenzoic acid (H3cpboda) in the presence of Ln(NO3)3. The complexes were characterized by single-crystal X-ray and powder diffraction, IR spectroscopy, elemental analysis and thermogravimetric analysis (TGA). All the structures of this family of lanthanide CPs are isomorphous with the triclinic space group P\overline{1} and reveal that they have the same 2D network based on binuclear LnIII units, which are further extended via interlayer C—H...π interactions into a three-dimensional supramolecular structure. The carboxylate groups of the cpboda3− ligands link adjacent LnIII ions and form binuclear [Ln2(RCOO)4] secondary building units (SBUs), in which each binuclear LnIII SBU contains four carboxylate groups from different cpboda3− ligands. Moreover, with the increase of the rare-earth Ln atomic radius, the dihedral angles between the aromatic rings gradually increase. Magnetically, CP6 shows weak antiferromagnetic coupling between the GdIII ions. The solid-state luminescence properties of CP2, CP5 and CP6 were examined at ambient temperature and CP5 exhibits characteristic red emission bands derived from the Eu3+ ion (CIE 0.53, 0.31), with luminescence quantum yields of 22%. Therefore, CP5 should be regarded as a potential optical material.

“…Metal-organic frameworks (MOFs) 1,2 are fascinating porous materials with unique properties compared with other families of porous materials. [3][4][5][6][7][8][9][10][11][12] They have several advanced applications, [13][14][15][16][17][18][19][20][21] including MOF-based nanozymes (MOFzymes). MOFzymes are promising for applications, such as sensing and cancer therapy, 22 and biomimetic catalysts.…”

“…Thus, several approaches were reported to reduce anthropogenic CO 2 concentration in the atmosphere. Applications of metal‐organic frameworks (MOFs), [ 4,3,13,28–34 ] including ZIFs for CO 2 adsorption are promising [ 22,35 ] for lowering the concentration of greenhouse gases in the atmosphere. [ 36–39 ] MOFs [ 40 ] have been applied as catalysts for the chemical fixation and photochemical reduction of CO 2 , [ 41 ] and as adsorbents.…”

Despite the great potential of two different pore regimes (hierarchical porous (HP) structure), HP‐zeolitic imidazolate frameworks‐8 (HPZIF‐8) can be efficient catalysts for hydrogen generation via hydride hydrolysis, and as adsorbents for CO2 gas adsorption. Herein, HPZIF‐8, and leaf‐like ZIF (ZIF‐L) are synthesized via a simple and environmentally friendly procedure using layered hydroxide nitrate of zinc (Z5HN) as a metal source and simple inorganic salt as a modulator. Z5HN nanosheets undergo topotactic transformation to simonkolleite (Zn5(OH)8Cl2·H2O) that can be converted to the pure phase of HPZIF‐8. The concentration of the salts tunes the textural properties of the final product. Applications of HPZIF‐8 and ZIF‐L for CO2 sorption exhibit excellent adsorption properties with increases of 25% due to the presence of cations in the frameworks. ZIF‐8 shows exceptional high catalytic activity for hydrogen generation via the hydrolysis of sodium borohydride. The simple synthesis of ZIF‐8 as well as their good performance as adsorbent and catalyst ensure the potential for industrial and commercial uses.
