Phosphorus-embedded porous organic polymers (P-POPs) play a vital role in catalysis and sustainable chemical synthesis. This study uses an olefin-linked P-POP to stabilize Pd nanoparticles that catalyze Larock's annulation to synthesize symmetrical indenones in high yields. Unsymmetric indenones were obtained with exclusive regioselectivities by employing an intramolecular dicarbofunctionalization of a modular alkyne. The approach addresses selectivity challenges in indenone synthesis and broadens the reaction scope by incorporation of aryl halides. The catalyst is robust and recyclable.

As an emerging catalytic strategy, heterogeneous Piezo-Self-Fenton (EPSF) has demonstrated significant potential in fields such as environmental remediation and biomedicine in recent years. However, the catalytic reactions in this process are complex and diverse, and the understanding of high-entropy catalytic systems remains limited. In this study, we constructed a series of iron-based EPSF materials by incorporating various types of iron sources into MgO@rGO/PVDF-HFP composite piezoelectric films.

Photo-stimulated Polymers have garnered significant attention for their potential applications ranging from optical memory to sensing. Herein, by changing coordination metal and the position of nitrogen atom in pyridine-based photo-stimulated ligand, we successfully synthesised a novel photo-stimulated copper-based MOF (Cu-MOF) using 9,10-bis(di(pyridine-3-yl)methylene)-9,10-dihydroanthracene as the photo-stimulated ligand. Structural analysis revealed a 3D porous architecture, offering a distinct advantage over previously reported 1D coordination polymer using similar photo-stimulated ligand.

This study investigated the effects of plasma electrolytic oxidation (PEO) treatment in a Ca- and P-rich electrolyte on the surface of the Ti-6Al-4V alloy with distinct α/β phase proportions previously induced by heat treatments. The results revealed that the α/β phase proportions were successfully altered by the heat treatment temperatures, forming α phase plates surrounded by β phase precipitates. PEO-treated samples exhibited a thick and microsized porous TiO coating in the anatase and rutile crystalline forms.

Water pollution is a critical environmental issue in modern society, and adsorption is recognized as a straightforward and efficient water purification technique. In this study, three new viologen-based ionic porous organic polymers were designed and successfully synthesized via a simple approach, and their adsorption properties for water pollutants were evaluated. The cationic nature of these polymers, coupled with their large conjugated π-electron system, physicochemical stability, and aromatic backbone, contributes to their high adsorption capacity and rapid adsorption efficiency for anionic contaminants in water such as Methyl Orange, Congo Red, and Cr (VI).

This study investigates the functionalization of a poplar biochar (PB), obtained by high-temperature pyrolysis, under oxidative conditions typically used in organic synthesis. In particular, concentrated nitric acid, a sulfonitric mixture and a piranha mixture were applied as oxidants at different temperatures and reaction times. In order to assess the outcome of the reaction conditions on the characteristics of the resultant products, these were characterized by a combination of imaging (SEM), spectroscopic (ATR-FTIR, RAMAN) and FFC-NMR relaxometric techniques.
