Nanostructures of a cobalt(II) metal–organic framework (MOF), denoted as 4,4′,4″-s-triazin-1,3,5-triyltri-p-aminobenzoate (TATAB) [[Co2(TATAB)(OH)(H2O)2].H2O.0.6O]n {1}, were successfully synthesized using two different experimental techniques: solvothermal and sonochemical strategies. Remarkably, both methods yielded an identical crystal structure. Various characterization techniques, including powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR), were employed to analyze all the compounds. Compound contains cobalt ions (Co2+) that were determined to be six-coordinated through the analysis of single-crystal X-ray diffraction (SCXRD). The effect of various factors such as temperature, reaction time, reactant concentration, and ultrasonic energy on the synthesis and final morphology of the compounds obtained by sonochemical method was investigated. Finally, Hirshfeld surface analysis (HAS) of compound was conducted. The molecular descriptors obtained at the BLYP/6–311 + + g (d, p) level of theory framework indicate a unique electronic structure for this complex, characterized by low chemical hardness (η = 1.702 eV), high electrophilicity (ω = 3.637 eV), and a narrow HOMO–LUMO gap (1.55 eV). These descriptors suggest that this complex can be considered a favorable nucleophile in interactions with proteins. [ABSTRACT FROM AUTHOR]

As a hybrid material, metal organic frameworks (MOFs) contain unique characteristics for biomedical applications such as high porosity, large surface area, different crystalline morphologies, and nanoscale dimensions. These frameworks are assembled through the interconnection of organic linkers with metal nodes, while the engineering of an MOF for biomedical applications requires versatile linkers with acceptable symmetry. Porphyrin, as an organic linker with interesting photochemical and photophysical properties, attracted the attention of many for engineering the potent multifunctional porphyrinic metal organic frameworks (PMOFs). In this regard, a large number of approaches were conducted for designing robust practical PMOFs with a wide range of applications. In this review, we introduced another perspective of MOFs and coordination polymers constructed from porphyrinic linkers with a special focus on those synthesized by meso-tetrakis (4-carboxyphenyl) porphyrin (TCPP). In the following, we summarized and discussed the different types of PMOFs and their biomedical applications in terms of diagnostic agent, therapeutic platform, and drug delivery vehicle.

ZPD is a type of metal–organic framework based on zinc ions. Its structure contains 2,5 pyridine dicarboxylic acid as ligand, and it was synthesized by the hydrothermal method. Its metal–organic framework has a high surface area, suitable micropores, and a very regular crystalline structure. In this study, Biginelli reaction and chromene synthesis were realized using Cu@ZPD as a catalyst. The prepared products were obtained with high-to-excellent yield (80–96%). The mentioned catalyst was identified by Fourier transform infrared (FT-IR), Brunauer–Emmett–Teller (BET), thermogravimetric analysis (TGA), X-ray diffraction (XRD), field emission–scanning electron microscopy (FE-SEM), energy-dispersive X-ray (EDX) mapping, transmission electron microscopy (TEM), and inductively coupled plasma optical emission spectroscopy (ICP-OES) analyses. By using ICP-OES, Cu loading was detected at nearly 3 wt%. The prepared catalyst can be reused 6 times without significantly losing its catalytic activity. Also, 1HNMR, 13CNMR, and FT-IR spectroscopy was used to identify the products. [ABSTRACT FROM AUTHOR]

Two metal-organic frameworks based on Cd(II) and 2-iodo-(2-I-Bdc) and 2,5-diodo-(2,5-I-Bdc)terephthalate were obtained: {[Cd(2-I-Bdc)(Bbi)]} (I) and {[Cd2(2,5-I-Bdc)2(DMF)2(Bbi)]} (II) (Bbi = 1,1'-(1,4-butanediyl)bis(imidazole)). The structures of both complexes were established by X-ray diffraction (CCDC no. 2258217 (I) and 2257566 (II)). [ABSTRACT FROM AUTHOR]
