Summary: In this study, 4-carboxy-TEMPO was selected as a representative SODm, and its ability to effectively promote the disproportionation reaction and accelerate the generation of singlet oxygen was chemically verified. It was found that the release of singlet oxygen evolved by the SODm was decreased when using a quencher. This study provides important reference for the development of additives for practical application of LOBs.

Summary: The study analyzed the quantum yields of singlet oxygen generated by heavy-atom-free BODIPY in three different solvents and successfully built a reliable QSPR model using new BODIPY compounds. The research confirmed the formation of triplet states through the SOCT-ISC mechanism. Predictions of phi Delta values using the MLR model showed promising statistical parameters, providing useful insights for virtual screening of new heavy-atom-free BODIPY with improved photosensitizing abilities.

Summary: This study investigates the photosensitizing properties of fullerene C-60 functionalized with organic units comprising thiophene or selenophene rings, which absorb longer-wavelength light. The chemical structures of the synthesized compounds were characterized and their absorptive and emissive properties were studied and correlated with their photosensitizing activity. One compound, C60ThSe2, was successfully used as a singlet oxygen source in a model photocatalyzed synthesis.

Summary: The antiviral action of various photosensitizers with potential lipid bilayer affinity has been summarized, with a focus on the generation of highly reactive singlet oxygen. Understanding of these data will drive a targeted search for substances with antiviral activity against enveloped viruses among photosensitizers able to bind to lipid membranes.

Summary: In this study, we prepared a material that can release CO and generate singlet oxygen simultaneously using dipico-lylamine appended BODIPY-manganese(I) tricarbonyl complexes embedded in a polymer matrix. The resulting non-woven fabrics showed CO release and singlet oxygen generation upon irradiation, and exhibited strong photocytotoxicity to c6 cancer cells. These fabrics possess rapid CO release, significant singlet oxygen generation, indefinite dark stability, good biocompatibility, and negligible dark toxicity, making them a promising candidate for phototherapeutic applications.

Summary: In this study, an S-C3N4/Ce2Zr2O7 organic-inorganic heterostructure was synthesized for the efficient photocatalytic removal of organic pollutants. The photocatalyst showed high activity for the dehalogenation of 2,4-dichlorophenol, 4-chlorophenol, and phenol under visible light. The S-scheme mechanism was proposed for the photocatalytic reaction pathway.

Summary: Cancer is a crucial health concern, and photodynamic therapy (PDT) shows promise for its treatment. This study focused on designing and synthesizing novel cyclotriphosphazene-based PDT agents decorated with BODIPY units for singlet oxygen generation. The introduction of halogen atoms enhanced the singlet oxygen generation ability. Preliminary PDT evaluation on cell lines demonstrated the success of these agents for light-dependent cell death in vitro.

Summary: Developing high-efficient, low-cost, and environmentally friendly catalysts for activating peroxymonosulfate (PMS) is a challenge. Novel catalysts of transition metal-nitrogen co-doped carbon materials, especially Fe-N-C, have shown superior performance for PMS activation. Through experiments, it is found that concave N, S co-doped iron-based carbon materials have significant activation ability for PMS and can efficiently degrade acetaminophen. Moreover, these materials have good pH adaptability and low leaching iron concentration.

Summary: This study investigates the ROS scavenging mechanisms of EGFP, demonstrating its high ability to quench various forms of ROS and suggesting a photoprotective role in living systems. Damage to the EGFP chromophore under strong photo-oxidative conditions was also observed. This research contributes to the understanding of the protective function of GFP-like proteins and their possible interactions with ROS in biological systems.

Summary: The antifungal performance and fluorescent probe potential of a series of squarylium dyes derived from indolenine and benzo[e]indole were evaluated. Photophysical properties and aggregate formation in phosphate buffer were studied. Singlet oxygen production was assessed using the 1,3-diphenylisobenzofuran assay. Antifungal activity was tested using Saccharomyces cerevisiae PYCC 4072, and some of the dyes showed improved activity after irradiation. Colocalization in yeast cells and the potential as a fluorescent probe for HSA detection were investigated.
