Summary: The study demonstrated that dinuclear aluminum complexes exhibited higher catalytic activity than mononuclear aluminum complexes, particularly those with 1,3-substituted phenyl ligands. One Al atom in the dinuclear Al system acted as an electron-withdrawing group, influencing the other Al atom through associated aromatic ligands, thereby enhancing catalytic activity for the ROP of CL.

Summary: Polymerization of biodegradable lactide and lactone has been extensively investigated. Density functional theory calculations were used to study the initiation and first propagation for ring-opening polymerization mechanisms of L-lactide (LA) and e-caprolactone (CL) on aluminum complexes. The results showed that the ROP mechanisms of LA and CL on different catalysts were classified into homopolymerization and copolymerization. The understanding gained in this study could contribute to the development of high-performance catalysts for biodegradable lactide and lactone ROP reactions.

Summary: Ring opening polymerization (ROP) is typically conducted using anhydrous reagents and inert atmosphere, which are barriers for non-experts. Here, two new techniques for limited ROP of epsilon-caprolactone (CL) without pre-drying reagents were developed using a laboratory oven. By evaporating water in a vacuum oven or polymerizing through water with titanium isopropoxide (TTIP), variable chain lengths and molecular weight distributions of PCL were achieved, with TTIP showing better performance for higher molecular weights and block copolymer formation.

Summary: A series of nine Zn(II) carboxylate complexes stabilized by monodentate pyridyl Schiff base ligands were synthesized and characterized. The molecular structures of these complexes were determined using single-crystal X-ray diffraction and found to have different nuclearities. These carboxylate complexes displayed good catalytic activity in the ring-opening polymerization of epsilon-caprolactone and rac-lactide at elevated temperatures. The catalytic activity was influenced by the nuclearity and coordination geometry of the complexes.

Summary: Density functional theory simulations were conducted to investigate the ring-opening copolymerization of epsilon-caprolactone and L-lactide using a novel gallium complex with an aminobis(phenolate) ligand. The results show that the copolymerization with this catalyst exhibits a faster polymerization rate for epsilon-caprolactone than for L-lactide, suggesting the formation of a predominantly block copolymer composed of epsilon-caprolactone and L-lactide.

Summary: Amphiphilic copolymers with interesting architecture and tunable properties are promising materials for biomedical applications. Enzymatic catalysis provides a suitable alternative for the preparation of these materials without the use of toxic catalysts. The structure-property relationship of copolymers was studied by varying the molecular weight of Pluronic (EPE) and the molar ratios between ε-caprolactone monomer and EPE macro-initiator (M/In). The obtained copolymers were chemically characterized and their morphologies evaluated. The results showed a correlation between the differential scanning calorimetry data and X-ray diffraction data, suggesting the importance of the central block length in crystal formation. Preliminary cytotoxicity experiments confirmed the non-toxic nature of the copolymers.

Summary: This work investigates the photocatalytic hydroxylation of benzene to phenol using a photoreactive polymer composite, N-doped TiO2 (N-TiO2) embedded into a syndiotactic polystyrene aerogel (N-TiO2/sPS). The composite exhibits enhanced phenol selectivity and yield compared to bare N-TiO2. The best results were achieved under visible light and acidic conditions, with a phenol selectivity of 98%, yield of 57%, and benzene conversion of 58%. The composite material can be recovered and reused without significant loss of photoreactivity and reduction in phenol yield.

Summary: We synthesized new hexadentate ligands with imine and pyridine nitrogen neutral donors, which have two coordinative pockets to promote the formation of bimetallic complexes. The bimetallic complexes S-1 and rac-1 were obtained by reacting the enantiomerically pure and racemic ligands with two equivalents of zinc amide precursor. Both complexes showed high activity in the polymerization of lactides under various reaction conditions and remained active even in technical grade melted lactide, demonstrating the robustness of the catalysts. Complex S-1 allows the production of linear or purely macrocyclic PLAs by back-biting reactions, depending on the reaction conditions. Mechanistic studies in NMR-scale solution were conducted to understand the active species in the polymerization process.

Summary: Chromium and aluminum complexes with salalen ligands were studied as catalysts for the ring-opening copolymerization (ROCOP) of succinic (SA), maleic (MA), and phthalic (PA) anhydrides with various epoxides. Their performance was compared to traditional salen chromium complexes. When used with 4-(dimethylamino)pyridine (DMAP) as the cocatalyst, all catalysts achieved a completely alternating enchainment of monomers to obtain pure polyesters. Switch catalysis allowed the same catalyst to combine the ROCOP of propylene oxide and maleic anhydride with the ring-opening polymerization (ROP) of glycolide (GA) in a one-pot procedure, resulting in a diblock polyester with precise composition.

Summary: The consumption and improper disposal of plastics have caused serious environmental concerns. New methods based on fluorescent tagging have been developed to facilitate the identification and sorting of different materials in plastic recycling. In this study, new fluorescent copolymers of polyethylene (PE) and polystyrene (PS) were synthesized and characterized for use as markers. These copolymers were found to have distinguishable fluorescent emissions even with a low concentration of only 1% in the PE/PS blends.

Summary: Experimental measurement and mathematical modeling were used to investigate the selective absorption of aromatic molecules (benzene, phenol, and toluene) from aqueous solutions by syndiotactic polystyrene (sPS) monolithic aerogels. The results showed high absorption efficiency for non-polar compounds (approximately 94% for toluene and approximately 77% for benzene) but poor absorption efficiency for the polar compound phenol (approximately 12%). NaCl did not affect the absorption efficiency of toluene and benzene, but phenol could not be removed from the aqueous phase in the presence of NaCl. These findings suggest that sPS aerogels can be used to selectively recover non-polar compounds from seawater.

Summary: In this study, a photocatalytic system utilizing a highly porous polymer containing commercial zinc sulfide and zero-valent iron catalyst (Fe/ZnS) was investigated for the degradation of PCE-contaminated groundwater. Experimental studies conducted on a pilot-scale photoreactor operating in continuous mode showed that PCE degradation in natural groundwater can reach 85-95%. A kinetic model was also developed and found to accurately describe the experimental data, allowing for potential scaling up of the photocatalytic system for PCE degradation.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
