Abstract
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.
期刊介绍:
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
