Summary: The detection and imaging of singlet oxygen is a challenging task due to its short half-life and solvent sensitivity. Selective probes for singlet oxygen are crucial in the presence of other oxidizing species, and smart designs are already making progress in pushing signalling events towards longer wavelengths of the visible spectrum.

Summary: A catalyst-free protocol for the purple light-mediated anti-Markovnikov functionalization of alkenes with thiols is presented. The generation of thiyl radical depends on the formation of a key photo-active complex. Over 30 thioether products were obtained, showing tolerance towards different functional groups and scalability up to 5 mmol of alkene. Two different reaction conditions have been developed, with the solvent and thiol amounts being varied. Water can be used as an alternative solvent to dichloromethane, increasing the sustainability of the entire process.

Summary: Novel metal-free and Mg(II) [3/4-(3,4-dicyanophenoxy)phenoxy]-substituted phthalocyanines with good solubility and fluorescence properties were synthesized and characterized. The complexes showed higher molar light absorption coefficients and fluorescence quantum yields compared to ligands. The magnesium [3/4-(3,4-dicyanophenoxy)phenoxy]phthalocyaninates exhibited efficient fluorescence-quenching and singlet oxygen generation, suggesting their potential application as PDT sensitizers.

Summary: Ruthenium complexes with protic diimine ligands exhibit cytotoxicity to cancer cells under blue light irradiation, likely due to singlet oxygen formation rather than photodissociation. Cellular studies have shown the generation of reactive oxygen species and apoptosis indicators upon treatment with specific complexes and blue light, highlighting their potential for targeted cancer therapy.

Summary: The study demonstrates that the use of highly spatioselective photochemistry can increase the structural complexity of MOF-based architectures, leading to the delamination of top layers and the formation of two-dimensional MOF sheets with defined thickness. This opens up new possibilities for fabricating planar MOF structures using photolithography.

Summary: Daylight-activated detoxifying nanofibrous membranes efficiently detoxify 1,3-dichloropropene (1,3-D) through a thiol-ene click reaction under daylight irradiation. The detoxification process is initiated and sustained by light-induced cascade chemical attacks of thiyl radicals, showing rapid and massive detoxification effects. These membranes also demonstrate a detoxification tailing effect in the absence of light sources, making them effective for personal protective equipment.

Summary: The research revealed that ligand design can control the mechanism of photooxidation. One of the Ru(II) complexes, Rudppz, enabled efficient turnover through supramolecular binding to facilitate cofactor oxidation, allowing repetitive conversion of naturally occurring nicotinamides by recognizing the redox state of the cofactor.

Summary: In this study, a dual-probe method combining hydrophilic 1O2 probe furfuryl alcohol (FFA) and its structural analogue furfuryl amine (FFAm) was used to quantify [1O2] in DOM samples. Results showed that the reactivity of FFAm was significantly higher than FFA at pH 7 and 8. The surface [1O2] of Suwannee River humic acid (SRHA) was determined to be 60 pM, which is 96-fold higher than the aqueous-phase [1O2] measured with FFA. This work expands the understanding of DOM microheterogeneous photochemistry and offers insights into the spatial distribution of 1O2 and other photochemically produced reactive intermediates.

Summary: This study investigates the spatiotemporal distribution of singlet-state oxygen (1O2) in organic aerosols (OA) through analyzing PM10 extracts in two locations in Switzerland. The results show that 1O2 concentration exhibits a seasonal variation, with a peak in wintertime. Biomass burning and anthropogenic secondary OA are identified as the main drivers for 1O2 formation. Furthermore, an empirical fit is developed to estimate 1O2 concentrations based on PM10 components.
