Summary: We have developed a novel diacylhydrazone-based fluorescent sensor, HMPD, for the detection of Al3+ ions. The sensor exhibited a significant fluorescence increment in the presence of Al3+ ions, with a stoichiometry of 1:2 for HMPD to Al3+. The detection limit of HMPD for Al3+ ions was determined as 0.76 μM. HMPD was able to determine Al3+ ions regardless of the presence of Ga3+ or In3+ ions. It was successfully applied for the qualification of Al3+ ions in real water samples and test strips. The sensing process of HMPD for Al3+ ions was reversible by EDTA application.

Summary: The novel tridentate N2O-type ligands L1-L4 and their dinuclear copper(II) complexes C1-C4 were synthesized and characterized. The structural forms of the copper complexes were determined using X-ray crystallography. The dinuclear copper complexes exhibited efficient ring-opening properties of epoxides with methanol, with C1 showing the highest reactivity due to the presence of an electron-donating group. The regiochemistry of the ring opening catalyzed by the dinuclear copper complexes appeared to depend on the electronic feature of the epoxide.

Summary: We describe a copolymeric fluorescent sensor that exhibits selectivity towards lithium chloride. The sensor is composed of two constituent polymers, one containing triphenylethylene (TPE) moieties for aggregate induced emission (AIE), and the other incorporating strapped-calix[4]pyrrole or secondary ammonium groups for self-assembly induced aggregation. Addition of LiCl in acetonitrile disrupts the host-guest crosslinks and leads to disaggregation of the polymer chains, resulting in decreased TPE emission. The lack of AIE perturbation upon addition of other salts demonstrates the high selectivity of the sensor towards LiCl. This supramolecular dual polymer approach can complement traditional sensor systems.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
