“…It was reported that Cu-MOFs possessed open coordination sites (OCSs), which were coordinatively vacatable sites at the metal center . H 2 O 2 , as a typical Lewis base molecule, could occupy the OCSs in Cu-MOFs to trigger a Fenton-like reaction . Channel features were considered to be the main factor influencing the coordination between H 2 O 2 and OCSs.…”

In situ synthesis of metal–organic frameworks (MOFs) on flexible materials for the fabrication of functional platforms and micro-devices is challenging. The time-/precursor-consuming procedure and uncontrollable assembly are stumbling blocks for constructing this platform. Herein, a novel in situ MOF synthesis method on paper substrates by use of the ring-oven-assisted technique was reported. Utilizing the ring-oven’s heating and washing function, MOFs can be synthesized in 30 min on the designated position of paper chips with extremely low-volume precursors. The principle of this method was explained by steam condensation deposition. The MOFs’ growth procedure was theoretically calculated by crystal sizes and the results conformed to the Christian equation. As different MOFs (Cu-MOF-74, Cu-BTB, Cu-BTC) can be synthesized successfully on paper-based chips, the ring-oven-assisted in situ synthesis method has great generality. Then, the prepared Cu-MOF-74 loading paper-based chip was applied to the chemiluminescence (CL) detection of nitrite (NO2 –), based on the catalysis effect of Cu-MOF-74 on the NO2 ––H2O2 CL system. Also, by the delicate design of the paper-based chip, NO2 – can be detected with the detection limit (DL) of 0.5 nM in whole blood samples without sample pretreatment. This work establishes a distinctive method for the in situ synthesis of MOFs and the application of MOFs on paper-based CL chips.

An interwoven channel in the Cu-BTB limited the Lewis base transport dynamics, so the CL performance was worst.…”

“…The additional peaks in the fitted curve at 939.81, 943.45, and 960.15 eV are satellite peaks, which confirm the presence of the Cu II ion. 31 As shown in Figure 3, compared with those of Cu (BDC-NH 2 ), all of the binding energies of C, O, N, and Cu in DE-15 have a small shift.…”

Mixed-linker metal−organic frameworks of Cu (BDC-NH 2 ) have been fabricated in which the 2-aminoterephthalic acid (BDC-NH 2 ) linker has been partially replaced by 3,5-pyridinedicarboxylic acid (PYDC) without obviously changing the crystal structure. The pyridine unit, as a defect site in the local coordination environment of the dimitic copper units, can alter the electronic structure. The experimental results of the photocatalytic reduction of Cr(VI) reveal that defect engineering can effectively modify the performance of metal−organic framework (MOF) materials with a much improved charge separation efficiency, band gap energy, and light adsorption, resulting in a significantly enhanced photocatalytic activity. The apparent rate constant of Cr(VI) reduction using defective Cu (BDC-NH 2 ) of DE-15 is 3.6 times higher than that of defect-free Cu (BDC-NH 2 ). More interestingly, DE-15 exhibits a relatively higher photocatalytic activity in contrast to the previously reported similar photocatalysts. The insight gained from this study will guide MOF defect engineering for enhancing the Cr(VI) photocatalytic reduction capacity.

This work presents the generation of a post‐synthetically modified Metal‐Organic Framework (MOF), denoted as Cu‐BDC‐NH2‐DHB, achieved through a Schiff‐base reaction by converting the pendant amino group in pristine Cu‐BDC‐NH2 MOF to an imine group using 3,4‐dihydroxybenzaldehyde (DHB). The resulting material exhibited exceptional luminescence and fluorescence stability in water, prompting investigation into its potential as a metal sensor. Fluorescence tests revealed that Cu‐BDC‐NH2‐DHB could be transformed into a highly selective and sensitive sensor for detecting Fe3+ ions amid co‐interfering metal ions, with a remarkable detection limit of 3.08 μM. Furthermore, the results demonstrated that Fe3+ induced a rapid and strong quenching effect, with a reaction time measured in seconds. This research provides a promising technique for the facile and immediate detection of Fe3+ ions in practical applications.
