“…So the whole framework of 8 can be topologically described as a binodal (4,5)-connected framework with the Schläfli symbol {4 4 ·6 2 }{4 4 ·6 6 } (Figure d). The architecture of 8 is very different from the reported complexes: {[Cd(L1)(hip)] · 4H 2 O} n and {[Cd(L2)(hip)]·3H 2 O} n ([L1 = N , N -di(pyridin-3-yl)pyridine-2,6-dicarboxamide, L2 = N , N -di(pyridin-3-yl)pyridine-3,5-dicarboxamide), which are based on the same metal center and auxiliary carboxylate. It can be seen that the different pyridyl-amide-based ligands show significant influence on the structural differences.…”

“…398 nm (λ ex = 280 nm) (398 for 1 , 398 for 2 , 397 for 3 , 398 for 4 , 397 for 5 , 400 for 6 , 403 for 7 , 396 for 8 , and 399 for 9 ), which are very close to that of free 4-bmpbd. The fluorescent emission of 1 – 9 can be attributed to the intraligand π* → π and n → π* transitions. , The difference of luminescent intensities among the title complexes might be ascribed to the different flexibilities and compactness of the structures and organic components …”

“…Therefore, the mixed ligand assembly system combining pyridyl-amide-based ligands with polycarboxylate anions has been applied for the construction of novel CPs with different dimensionalities . In recent years, our group also investigated the assembly of polycarboxylate-assisted pyridylacylamide-based CPs with various dimensionalities and functions . Nevertheless, reports on a mixed ligand assembly system of special bis-pyridyl-bis-amide and polycarboxylates with different substitute groups, carboxyl position, and number are still limited.…”

Nine new Cd(II) coordination polymers (CPs) including [Cd3(4-bmbpd)4Cl6(H2O)2] (1), [Cd(4-bmbpd)(2,2′-BDC)(H2O)] (2), [Cd(4-bmbpd)(OBA)]·H2O (3), [Cd(4-bmbpd)0.5(ADTZ)(H2O)]·H2O (4), [Cd4(4-bmbpd)(1,3-ATDC)4(H2O)6]·2H2O (5), [Cd(4-bmbpd)(3-NPH)(H2O)]·H2O (6), [Cd(4-bmbpd)0.5(NIP)(H2O)] (7), [Cd(4-bmbpd)0.5(HIP)]·H2O (8), and [Cd3(4-bmbpd)2(1,3,5-BTC)(H2O)4]·4H2O (9) (4-bmbpd = N,N′-bis(4-methylenepyridin-4-yl)-1,4-benzenedicarboxamide, 2,2′-H2BDC = 2,2′-biphenyldicarboxylic acid, H2OBA = 4,4′-oxybis(benzoic acid, H2ADTZ = 2,5-(s-acetic acid)dimercapto-1,3,4-thiadiazole, 1,3-H2ATDC = 1,3-adamantanedicarboxylic acid, 3-H2NPH = 3-nitrophthalic acid, H2NIP = 5-nitroisophthalic acid, H2HIP = 5-hydroxyisophthalic acid, and 1,3,5- H3BTC = 1,3,5-benzenetricarboxylic acid), have been produced with a hydrothermal/solvothermal technique and structurally characterized by single-crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analysis, and infrared spectroscopy. Complex 1 exhibits a one-dimensional (1D) wave-like double chain constructed from [Cd3(4-bmbpd)2Cl6(H2O)2] subunits and μ2-bridging 4-bmbpd ligands. 2 is a two-dimensional (2D) 4-connected layer consisting of 1D [Cd-4-bmbpd] n zigzag chains and 1D [Cd-2,2′-BDC] n single-strand helix chains. Complex 3 is also a 2D 4-connected network constituted of 1D [Cd-OBA] n linear chains and [Cd(4-bmbpd)] n wave-like chains. Complex 4 has a (2,4,4)-connected 2D architecture based on [Cd2(ADTZ)2] rings and μ4-bridging 4-bmbpd ligands with {42·82·102}{ 42·84}2{4}2 topology. Complex 5 exhibits an intriguing 1D chain constructed from [Cd4(1,3-ATDC)4] rings and μ2/μ4-bridging 4-bmbpd ligands. Complex 6 presents a 1D ladder-shaped chain. Complex 7 displays a 3D (4,4)-connected framework giving an interesting self-penetrating structure. Complex 8 is a 3D (4,5)-connected architecture with {44·62}{44·66} topology. 9 shows a 3D (2,3,4,4)-connected framework, which contains [Cd-1,3,5-BTC] n 1D double chains. The versatile structures reveal the impact of the carboxyl position and number, the flexibility, as well as the functional groups of polycarboxylate auxiliary ligands on the architectures. Furthermore, the effects of different organic solvents on the fluorescent behaviors of 1–4 and 7–9, and the photocatalytic properties of 1–9 under UV irradiation, were studied.

Photocatalytic Decontamination of Wastewater Containing Organic Dyes by Metal–Organic Frameworks and their Derivatives

et al. 2016

View full text Add to dashboard Cite

Photoactive metal–organic frameworks (MOFs) have lately emerged as a class of crystalline porous materials, which provides an advanced platform to develop catalysts for the photocatalytic decolorization of wastewater. Controllable integration of pure MOFs into other active materials creates fabrication protocols for new multifunctional hybrids with superior photocatalytic properties for dye degradation into individual components, and the calcination of transition‐metal MOF precursors affords a convenient and practical route for preparation of nanosized photocatalysts with novel structures and good purity. Although the application of pure MOFs for organic pollutant decomposition has been reviewed previously, there have been significant advances in diverse MOF‐based composites and their derivatives for dye degradation, which have rarely been reviewed. This review aims to fill this gap and discuss the various influencing factors, the reaction kinetics, and mechanisms of dye degradation, considering the period from 2014 to 2016. Finally, the challenges and outlooks for dye decomposition by MOF‐based materials are suggested.

Two 3D Zn(II) networks based on 1,4-bis(2-methylimidazol-1-ylmethyl)-2,3,5,6-tetramethylbenzene (bmimx), namely, {[Zn 4 (m 4 -O)(m 2 -H 2 O)(1,3,5-BTC) 2 (bmimx)]·H 2 O} n (1) and {[Zn 2 (m 2 -OH)(1,2,4-BTC)(bmimx)(H 2 O)]·2.5H 2 O} n (2) (1,3,5-H 3 BTC = 1,3,5-benzenetricarboxylic acid, 1,2,4-H 3 BTC = 1,2,4-benzenetricarboxylic acid) have been prepared at hydrothermal condition by varying the benzenetricarboxylic ligands. Single-crystal X-ray diffraction indicates that complex 1 shows a (3,8)-connected net based on tetranuclear zinc(II) clusters; complex 2 shows a 8-connected framework based on 18-membered tetranuclear zinc(II) macrometallacycles. The results indicate that benzenetricarboxylic ligands have an important effect on the stuctural characters and ultimate frameworks. Moreover, the photoluminescence properties of the two complexes were studied in the solid state at room temperature.[a] Dr.
