Summary: A series of BODIPY heterooligomers were prepared and investigated for their excitation energy transfer processes, demonstrating both strong and weak coupling limits. The impact of stabilizing beta-ethyl substituents on conformational space and electronic couplings was addressed, revealing one of the fastest excitation energy transfer processes detected to date. Transient-absorption spectroscopy combined with dynamic simulations provided a consistent framework to elucidate the limitations of Förster resonance energy transfer theory.

Summary: In this study, two bridged carborane-anthracene dyads with dual state emission (DSE) properties were reported. Compound 2 was obtained by reducing carboranyl Schiff base 9-anthracenylidene-1-amino-o-carborane (1) with NaBH4. The photophysical properties and mechanochromism of both compounds and their silica gel composites were investigated. This work provides a simple strategy for designing and synthesizing novel carborane-containing DSE compounds and regulating solid-state luminescence for potential applications.

Summary: We synthesized three new dyads composed of a Zn porphyrin and fac-Re(bpy)(CO)(3)Br units, and investigated their photophysical properties and catalytic activity in CO2 reduction. Among the three dyads, ZnP-5Bpy=Re-Br showed the highest durability and reaction efficiency, reaching a reaction quantum yield of 24%. The significant activity in ZnP-5Bpy=Re-Br is attributed to the absence of electron accumulation on the Zn porphyrin, facilitated by dual interactions of triethanolamine (TEOA) with the Re and Zn ions in the dyad. The catalytic activities and RTP properties are considered independent but greatly influenced by the connecting positions on the bpy ligand in ZnP-nBpy=Re-Br.

Summary: Rational design and synthesis of highly efficient photocatalysts with positive exciton splitting and interfacial charge transfer is essential for environmental applications. In this study, a novel Ag-bridged dual Z-scheme g-C 3 N 4 /BiOI/AgI plasmonic heterojunction was successfully synthesized, demonstrating exceptional photocatalytic degradation efficiency of tetracycline in water and good stability. The improved performance and stability were attributed to the highly ordered 3D porous framework, fast electron transfer of dual Z-scheme heterojunction, desirable photocatalytic performance of BiOI/AgI and synergistic effect of Ag plasmas. This research provides new insights and guidance for designing novel structural photocatalysts for environmental applications.

Summary: This article reports on efforts to develop in vitro assays to reliably identify molecules that can destabilize G4s. The workflow includes a newly designed G4-unfold assay, adapted from the G4-helicase assay with Pif1, as well as biophysical and biochemical techniques traditionally used to study G4/ligand interactions, and a qPCR stop assay adapted from a Taq-based protocol to identify G4s in genomic DNA. This multipronged approach leads to the characterization of a phenylpyrrolocytosine (PhpC)-based G-clamp analog as a prototype of a G4-disrupting small molecule.

Summary: In this study, a ternary system consisting of two small molecules (B2 and B3) as donors and a narrow bandgap non-fullerene small molecule acceptor Y6 was designed for organic solar cells. The presence of B2 in the B3:Y6 blend increased photon harvesting and formed cascade energy level structure, facilitating the charge transfer. Efficient energy transfer from B2 to B3 was observed, resulting in effective exciton utilization in the ternary device. The ternary device achieved an efficiency of approximately 12.88% with low energy loss, surpassing that of binary devices with B2:Y6 and B3:Y6 blends.

Summary: In this study, carboxylic acid corroles with one, two, three, or four carboxylic groups were synthesized and evaluated as gram-positive antibacterial agents against two strains of S. aureus, including methicillin-sensible and methicillin-resistant strains. Two lead compounds, 5 and 6, exhibited low MICs of 0.78 μg/mL against both strains. These previously underexplored molecules can serve as a new scaffold for antimicrobial development.

Summary: In this study, the synthesis, characterization, and gas adsorption properties of new 2D and 3D covalent organic frameworks (COFs) based on corrole macrocycles were reported. The materials were synthesized using readily available aldehyde as platforms and diamine-functionalized free-base corrole as building block linker. Cobalt-metalated COFs were also synthesized to obtain porous materials. The structure and performance of the materials for carbon monoxide (CO) adsorption were investigated using various spectroscopy analyses and sorption measurements. The results showed that 2D-COF-CorCo exhibited the highest adsorption capacity for CO with high selectivity over other gases.

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.
