“…Additionally, the stretching vibrations of the OTf − anions appeared at 1278, 1026, and 1159 cm −1 , respectively [51][52][53][54][55]. Additionally, the vibration of aromatic ring of ligand L1 is likely at 1615 and 1421 cm −1 [56][57][58][59][60]. In addition, a strong signal at 575 cm −1 could be attributed to the Cu-O bonding signal of building block E3 (Figure 12).…”

The controlled synthesis of organometallic supramolecular macrocycles cages remains interesting and challenging work in the field of supramolecular chemistry. Here, two tetranuclear rectangular macrocycles and an octuclear cage were designed and synthesized utilizing a rigid and functionalized pillar linker, 2,6-bis(pyridin-4-yl)-1,7-dihydrobenzo [1,2-d:4,5-d′]diimidazole (BBI4PY) based on three half-sandwich rhodium building blocks bearing different sizes. X-ray crystallography in combination with 1H NMR spectroscopy elucidated that the two building blocks with shorter spacers only result in rectangular macrocycles. However, the building block of bulkier size to avoid the π-π stacking interactions between two ligands BBI4PY led to the formation of an octuclear cage complex. The latter cage contains two types of metal ions, namely Rh3+ and Cu2+, showing significant characteristics of heterogeneous metal-assembling compounds. In addition, the cage accommodates two free isopropyl ether solvent molecules, thus displaying host–guest behavior.

“…[ 13 , 14 ]. Meanwhile, MOFs, as a kind of novel porous metal-organic framework material, due to their high specific surface area, large porosity, and good structural stability have shown wide application prospects in gas adsorption [ 15 , 16 , 17 ], sensors [ 18 , 19 , 20 ], magnetic [ 21 , 22 , 23 , 24 , 25 ] optical materials [ 26 , 27 , 28 , 29 , 30 , 31 , 32 ], and catalysts [ 33 , 34 , 35 , 36 ], etc. Additionally, the MOF materials have been utilized to perform photocatalytic hydrogen production [ 37 , 38 , 39 , 40 , 41 ] and carbon dioxide reduction reactions [ 42 , 43 , 44 , 45 ].…”

Herein, a new Zn-MOF material, [Zn(L1)(L2)], 1, was built successfully through a one-pot solvothermal method. The 3D MOF structure was determined by Single X-ray diffraction analysis, IR, and elemental analysis. A series of PXRD tests of 1 after being immersed in different solvents and pH solutions demonstrated the good stability of 1. Interestingly, this material displayed high catalytic activity for the visible-light-driven hydrogen generation under the illumination of white LED in pure water or a mixture of DMF and H2O without additional photosensitizers and cocatalysts. Besides, the studies also showed that the catalytic activity changed constantly as well as the solvent ratio adjustment of DMF and H2O from 4:6 to 2:8. Additionally, the catalytic activity reached the best value (743 μmol g−1 h−1) when the solvent ratio was 4:6. The heterogeneous nature and recyclability of the MOF catalyst, as well as several factors that affect the catalytic activity, were investigated and described in detail. Moreover, the photocatalytic mechanism for the hydrogen generation of 1 was also proposed based on the fluorescence spectra and UV-vis absorption.

“…However, the disadvantages of the poor photostability and biodegradation of these materials hinder their further application [8][9][10]. As a new type of crystalline porous inorganic−organic hybrid material, metal-organic frameworks (MOFs) have aroused widespread concern among scientists due to their large specific surface area, highly tunable structures, modular porosity, and structural stability [11][12][13][14][15][16][17]. Therefore, various MOF structures, such as MOF-5, MOF-74, ZIF-8, and UTSA-74, have been constructed successfully through various methods; their properties, such as gas adsorption, catalysis, sensors, photoelectric performance, and photothermal effect, have also been explored [18][19][20][21][22][23][24][25].…”

Stable Nickel-Based Metal–Organic Framework Containing Thiophene/Diimidazole Units for Effective Near-Infrared Photothermal Conversion

Herein, a new Ni-based metal–organic framework (MOF, 1) bearing highly structural stability is synthesized by the reaction of utilizing a rigid and functionalized linker, 2,6-bis(pyridin-4-yl)-1,7-dihydrobenzo[1,2-d:4,5-d′]diimidazole (BBI4PY), in combination with Ni(NO3)2·6H2O and dibenzo[b,d]thiophene-3,7-dicarboxylic acid 5,5-dioxide (L1) under solvothermal conditions. The crystal structure of complex 1 is determined by single-crystal X-ray diffraction and is demonstrated to be a two-dimensional layered structure. In addition, PXRD, IR, TGA and UV/Vis-NIR spectra are also tested carefully to explore the solid structure of this complex. Remarkably, although no significant accumulation effect could be observed between the two-dimensional layers, a stacking interaction between DMF solvent molecules and ligand L1 could be found, which might promote non-radiative transitions and trigger obvious near-infrared photothermal conversion. Under 660 nm laser (0.6 W cm−2) illumination, the temperature of complex 1 increased rapidly from room temperature to 45.2 °C, with good thermal stability and cycle durability. Its photothermal conversion efficiency could reach 10.75%. This work provides an efficient way for assessing the promise of materials in the field of photothermal therapy.
