“…As seen in Figure 2c, Zr 3d exhibited two main peaks at 182.9 and 185.3 eV in Zr-terephthalic acid (Zr-BDC), corresponding to ZrÀ O linkage in the frameworks. [18] In addition, a new ZrÀ N peak at 183.6 eV emerged in Zr-IDA, indicating the coordination participation of N. This can be further confirmed from N1s XPS spectra in Figure 2d where a N1s peak was found at 399.5 eV, corresponding to pyrazole nitrogen. [16] Pyrazole nitrogen of H 2 IDA was originally deconvoluted to two peaks at 399.1 eV and 399.7 eV.…”

Rational ligand design is crucial for achieving widespread applications of coordination polymers. The preparation, structural characterisation, and catalytic applications of zirconium (IV) coordination polymer (Zr-IDA), which was derived from 1-(carboxymethyl)-1H-indazole-5-carboxylic acid are reported. The Zr-IDA catalyst contains porous and highly crystalline particles with a quasi-spherical morphology around 100 nm in size, and Zr was coordinated with both O and N as shown by FT-IR and XPS measurements. Importantly, the Zr-IDA catalyst shows great activity, selectivity and stability in the oxidative coupling of benzyl cyanides with tert-butyl hydroperoxide to afford tertbutyl peresters, and the dehydrogenation cyclization of ophenylenediamines with aromatic alcohols to afford 1,2-disubstituted benzimidazole derivatives. Mechanistic investigations were carried out to study these reactions and the developed catalytic system in more detail.[a] Dr.

“…The powder XRD characterization of Zr-based MOF presents three typical diffraction peaks at 4.8°, 7.1°, and 9.8° (Figure 2 A), which is in accordance with the previous reports. 48 Besides, the XPS spectrum for Zr-based MOFs indicates the presence of C, N, O, and Zr (Figure 2 B). Collectively, these results confirm successful preparation of the Zr-based MOF nanostructures.…”

Purpose: Early diagnosis of cancer enables extended survival and reduced symptoms. To this end, a “three-in-one” nanohybrid of MOF@AuNP@GO is designed as synergistic nanoquencher to develop a novel fluorescence biosensor for rapid and sensitive detection of cancer-related biomarkers.Methods: The ssDNA absorption affinities and fluorescence quenching abilities of the MOF@AuNP@GO were evaluated using FAM-labeled single-stranded DNA (ssDNA). Then, two specific dye-labeled ssDNA and aptamer probes were designed for the recognition of p53 gene and prostate specific antigen (PSA), respectively. Fluorescence spectra were recorded and ratiometric signal processing was performed.Results: The designed nanohybrids exhibit enhanced ssDNA binding affinities and fluorescence quenching abilities, which significantly decrease the background signal and increase the signal-to-noise (S/N) ratio, thus lowering the detection limit (LOD). Accordingly, with ratiometric measurement, this developed nanosensor can sensitively measure p53 gene and PSA with LODs of 0.005 nM and 0.01 ng mL-1, respectively. Besides, this method also displays excellent performances with respect to universality, multiplexed detection, specificity, and practicality in human serum.Conclusion: The designed MOF@AuNP@GO-based fluorescence biosensor can serve as a promising platform for washing-free, rapid and sensitive measurement of cancer biomarkers, making this method well-suited for point-of-care (POC) diagnosis.

“…More importantly, given that the aromatic compounds are comparatively more stable than the antiaromatic species, which exhibit antiaromatic destabilization, the overall performance of these materials can be tuned by controlling the nature of the organic groups or by introducing metal heteroatoms into the hybrid structure. In comparison to quinones or pristine organic ligands, the energy of the HOMO–LUMO gap for these hybrid materials is very low . It is noteworthy to mention here that a smaller HOMO–LUMO gap allows for facile injection and removal of electrons and ultimately leads to higher capacity utilization.…”

Bioderived Molecular Electrodes for Next‐Generation Energy‐Storage Materials

Nature‐derived organic small molecules, as energy‐storage materials, provide low‐cost, recyclable, and non‐toxic alternatives to inorganic and polymer electrodes for lithium‐/sodium‐ion batteries and beyond. Some organic carbonyl compounds have met or exceeded the voltages and gravimetric storage capacities achieved by traditional transition metal oxide‐based compounds due to the metal‐ion coupled redox and facile electron‐transport capability of functional groups. Stability issues that previously limited the capacity of small organic molecules can be remediated with reactions to form insoluble salts, noncovalent interactions (hydrogen bonding and π stacking), loading onto substrates, and careful electrolyte selection. The cost‐effectiveness and sustainability of organic materials may further be improved by employing porphyrin‐based electrodes and multivalent‐ion batteries utilizing abundant metals, such as aluminum and zinc. Finally, redox flow batteries take advantage of the solubility of organics for the development of scalable, high power density, and safe energy‐storage devices based on aqueous electrolytes. Herein, the advantages and prospects of small molecule‐based electrodes, with a focus on nature‐derived organic and biomimetic materials, to realize the next‐generation of green battery chemistry are reviewed.
