Summary: This study investigates the relationship between morphology and catalytic performance of metallo-supramolecular assemblies in photocatalytic CO2 reduction. It is found that the fibrous-like gel assembly exhibits the best catalytic performance with a yield of 6.3 mmol g-1 h-1 and 94.7% selectivity for CO generation. Photoelectrochemical measurements, photo-luminescence quenching experiments, and UV-vis absorption spectroscopy studies suggest that the ligand-based electron transfer of the gel is more efficient compared to the other two assemblies.

Summary: We have developed mesoporous boron dipyrromethene-bridged coordination polymer nanophotosensitizers (BCP-NPs) for effective photodynamic therapy. The unique assembly strategy results in enhanced photodynamic activities, high cellular uptake, and ultrahigh stability of BCP-NPs. Furthermore, BCP-NPs demonstrate excellent tumor accumulation and prolonged retention, leading to the eradication of triple-negative breast cancer (TNBC) under low-power-density LED irradiation. This study provides a valuable paradigm for the construction of mesoporous photoactive nanomaterials in biophotonic applications.

Summary: Main group indium materials are found to be efficient electrocatalysts for two-electron-involved carbon dioxide reduction to produce formate. However, the synthesis of 2D monometallic nonlayered indium remains challenging. In this study, a facile electrochemical reduction strategy is introduced to transform 2D indium coordination polymer into elemental indium nanosheets. The reconstructed metallic indium exhibits high Faradaic efficiency for formate, with excellent catalytic performance attributed to the enhanced exposure of active sites and mass/charge transport at the triple-phase interface and the restrained electrolyte flooding.

Summary: Light-driven fixation of CO2 in organics is achieved using boron carbonitride with abundant terminal B/N defects, leading to enhanced surface active sites and charge transfer kinetics. This enables the anti-Markovnikov hydrocarboxylation of alkenes with CO2, achieving good functional group tolerance and specific regioselectivity under visible-light irradiation. Mechanistic studies demonstrate the formation of CO2 radical anion intermediate on defective boron carbonitride, enabling the anti-Markovnikov carboxylation. The utility of this method is demonstrated through gram-scale reactions, late-stage carboxylation of natural products, and synthesis of anti-diabetic GPR40 agonists.

Summary: Organic synthesis driven by solar energy is gaining attention for its advantages of selectivity and milder reaction conditions. However, the inefficient utilization efficiency due to slow charge separation limits its catalytic performance. Assembling 0D/2D Z-schemed semiconductor nano-heterojunctions can be a promising solution. In this study, 0D/2D carbon nitride quantum dots (CNQDs)/Bi2MoO6-x (BMO-OD) was synthesized, showing superior catalytic activity for amine oxidation coupling under ambient conditions. The design and synthesis of 0D/2D CNQDs/BMO-OD can enhance the photoinduced charge carriers' separation kinetics, promoting the photocatalytic oxidation coupling of amines under mild conditions.

Summary: Doping or ion substitution is widely used to improve the photocatalytic activities of semiconductors, and this study focuses on ion substitution in Bi2WO6. The electronegativity of the dopant can be used to tune the band-edge potentials, and this affects the photocatalytic mechanism. I-doped Bi2WO6 shows higher selectivity and improved morphologies, band-gap energy, and carrier recombination compared to Te-doped Bi2WO6. The findings highlight the importance of dopant choices in photocatalytic reactions.

Summary: In this study, atomic strain modulation was successfully achieved on ultrathin layered vanadium oxide nanoribbons by utilizing an ingenious intercalation chemistry method. The introduction of trace sodium cations between the V2O5 layers resulted in the stretching of V-O bonds by atomically strained vanadium sites, leading to redistribution of local charges. The atomically strained Na+-V2O5 exhibited remarkable photooxidation performance, which was approximately 12 and 14 times higher than that of pristine V2O5 and VO2, respectively. Spectroscopy analysis and theoretical calculations confirmed that the atomically strained Na+-V2O5 possessed a high surficial charge density, enhancing the activation of oxygen molecules and contributing to the excellent photocatalytic property. This work presents a new approach for the rational design of strain-equipped catalysts for selective photooxidation reactions.

The density functional theory (DFT) calculation reveals the multiple-active sites for Na-ion storage in NiQAP. These results emphasize the importance of organic electrode material with coordination units for energy storage systems and lay a foundation for future studies on CCPs with multiple active sites.

Summary: We present an efficient visible light-driven CO2 reduction system that operates in water without the use of noble metals or rare materials. By employing a cobalt complex as a catalyst, an organic triazatriangulenium salt as a photosensitizer, and BIH + TEOA as a sacrificial reductant, we achieved CO and formate production with high selectivity and total turnover numbers exceeding 3700. The addition of a weak Brönsted acid further improved the catalysis, resulting in a selectivity of 93% and a total turnover number of 19,000 for CO production. The photocatalytic system demonstrated excellent performance even in pure water, with a turnover number of 2600 and a selectivity of 94% using TEA as the sacrificial reductant.

Summary: This article introduces a synthesis method for epoxy dienone products starting from para-substituted phenols bearing an electron-deficient alkene. The one-pot photooxygenation/epoxidation reaction can proceed at room temperature under green light irradiation with catalytic amounts of Rose Bengal and cesium carbonate. The reaction provides a range of functionalized epoxy dienone products with diastereoisomeric ratios ranging from 4:1 to > 12:1. DFT calculations and mechanistic experiments demonstrate that the reaction proceeds through singlet oxygen-mediated photooxidation of phenols followed by an intramolecular oxygen atom transfer on the alkene side arm.
