The mol-ecule of the title compound, [NaNi(C(18)H(18)N(2)O(4))(ClO(4))(CH(3)OH)], is almost planar, the maximum deviation from the molecular plane being 5.3 (1) Å. The Ni(2+) ion is N(2)O(2) coordinated by the Schiff base ligand, leading to a slightly distorted square-planar environment. The Na atom is chelated by the four O atoms of the Schiff base ligand and is coordinated by the O atoms of a methanol ligand and a perchlorate anion. The perchlorate ion is disordered over two sites with occupancies 0.723 (12):0.277 (12).

Using CO as the C1 source for N-formylation of amine is a crucial energy-storage pathway to address the greenhouse effect while generating high-value-added chemicals but is limited by the activation of inert molecules. Herein, a dual active site catalyst with high CO activation and dihydrogen dissociation capacity was fabricated by incorporating a Schiff base and Au nanoparticles (NPs) on silicon dioxide (SiO). The modification of the Schiff base not only provides an alkaline environment for CO absorption but also stabilizes Au NPs in a small and highly dispersed state, which regulates the electronic density of the metal for excellent H cleavage.

Covalent organic frameworks (COFs) are a promising platform for heterogeneous photocatalysis due to their stability and design diversity, but their potential is often restricted by unmanageable targeted excitation and charge transfer. Herein, a bimetallic COF integrating photosensitizers and catalytic sites is designed to facilitate locally ultrafast charge transfer, aiming to improve the photocatalytic reduction of CO. The strategy uses a "one-pot" method to synthesize the bimetallic COF (termed PBCOF) through in situ Schiff-base condensation of Pyrene with MBpy (M = Ru, Re) units.

In this investigation, a novel tetradentate Schiff base ligand, (ligand L) was synthesized using a simple chemical route assisted by triethylenetetramine with 4-dimethylaminocinnamaldehyde in ethanol. The chemical structure of the as-synthesized ligand was characterized using nuclear magnetic resonance (NMR) and UV-visible spectroscopy. This ligand was then employed to modify the working electrode of screen-printed carbon electrode (SPCE) for developing a modified L/SPCE sensor finalized to detection of lead ions (Pb).

The widespread use of copper (Cu) has raised concerns about environmental pollution and adverse effects on human health, highlighting the need to develop copper detection methods. Developing near-infrared (NIR) luminescent probes for imaging subcellular Cu is still a challenge. In this work, we have developed a luminescence probe based on a NIR iridium(III) complex, which rapidly detects Cu by combining salicylaldehyde and amine groups through a simple Schiff base reaction on the N^N ligand.

The oxidation of 5-HMF to HMFCA is an important yet complex process, as it generates high-value chemical intermediates. Achieving this transformation efficiently requires the development of non-precious, highly active catalysts derived from renewable biomass sources. In this work, we introduce UoM-1 (UoM, University of Mazandaran), a novel cobalt-based metal-organic framework (Co-MOF) synthesized using a simple one-step ultrasonic irradiation method.
