Summary: The study found that a BODIPY derivative showed a significant enhancement in singlet oxygen sensitization quantum yield with the decrease of solvent dielectric constant. Triplet state formation for the derivative was mediated by intramolecular charge transfer state in toluene, while hindered by fast recombination of the ICT state in polar solvents. The photoinduced dynamics of the BODIPY derivatives were characterized from femtosecond to nanosecond time scale using pump-probe transient absorption spectroscopy.

Summary: By studying the AgBiS2/Pc heterojunction, transient absorption spectroscopy was used to investigate singlet fission and carrier transfer processes. The transfer of triplets from pentacene to AgBiS2 and the transfer of holes from AgBiS2 to pentacene were observed. Singlet fission in pentacene was enhanced by modifying the crystallinity of the pentacene layer, and the first singlet fission AgBiS2/Pc solar cell was successfully fabricated. Singlet fission devices demonstrated higher external quantum efficiency, indicating the significant contribution of charges from the singlet fission process.

Summary: The study directly probes the free-carrier dynamics in Cs-doped FAPbI(3) thin films using spatiotemporal photoconductivity imaging, revealing that the lifetimes of electrons and holes in the material are compensated by their disparate mobility, resulting in comparable long diffusion lengths for both carriers. This unique charge trapping and de-trapping processes in hybrid trihalide perovskites play a crucial role in determining the superior diffusion dynamics of the material, which is vital for solar-cell applications.

Summary: Amphipathic perylene derivatives are effective antiviral compounds that target the viral envelope and act as fusion inhibitors. They damage the viral envelope using lipophilic perylene and singlet oxygen generated by light. Short alkyl chains contribute to strong antiviral activity, while longer alkyl chains reduce activity due to increased lipophilicity and aggregation.

Summary: In recent years, PDI-based supramolecular photocatalysts have attracted significant attention. The charge localization effects hinder the charge transfer in PDI, resulting in a high recombination rate and limited activity. This study developed three heteroatom bay-annulated perylene diimide supramolecule photocatalysts (N-APDI, S-APDI, and Se-APDI) for photocatalytic H2 evolution. Under visible-light irradiation, heteroatom-annulated PDI supramolecules exhibited better H2 evolution rate than non-heteroatom APDI, with N-APDI showing the highest hydrogen production rate of 61.49 mmol g-1 h-1 and an apparent quantum yield (AQY) of 5.90% at 420 nm. The improved photocatalytic activity of heteroatom-annulated PDI supramolecules can be attributed to stronger molecular dipole, which enhances the internal electric field magnitude and promotes charge separation and migration. Furthermore, heteroatom annulation can act as a more beneficial active site to promote HER activity. This work provides a new strategy for the development of supramolecular photocatalysts.

Summary: We demonstrate an enhanced photo-Seebeck effect in air-stable MAPbI(3) perovskite through optical gating. Illumination by a laser diode leads to a significant increase in both the Seebeck coefficient and electrical conductivity. The n-type MAPbI(3) perovskite with residual PbI2 shows higher Seebeck enhancement and photoconductivity compared to the p-type perovskite. This indicates that the presence of PbI2 accelerates photoinduced charge transfer at the interface, resulting in dedoping and enhanced photo-Seebeck effect.

Summary: Singlet fission (SF) materials have been used to improve the power conversion efficiency (PCE) of solar cells. However, SF implementation in perovskite solar cells has not been successful due to the lack of understanding of the SF/perovskite heterojunctions. In this study, the charge dynamics between a well-known SF molecule, TIPS-pentacene, and a triple-cation perovskite Cs-0.05(FA(0.85)MA(0.15))(0.95)PbI2.55Br0.45 were investigated. The results show that there is an electron-transfer process from TIPS-pentacene to perovskite, leading to an increase in carrier density in the perovskite layer. This study confirms the potential of SF-enhanced perovskite solar cells.

Summary: Multidimensional hierarchical hollow Co3O4/ZnIn2S4 tubular core-shell heterostructures were prepared by growing ultrathin 2D ZnIn2S4 nanosheets on 1D hollow Co3O4 nanotubes using a solvothermal method. This design not only prevents the self-assembly aggregation of ZnIn2S4 nanosheets, but also broadens their light-absorption range and enhances the utilization of visible light. The p-n heterojunction in the photocatalyst generates an internal electric field, which facilitates the separation and migration of photogenerated charge carriers and effectively suppresses their recombination.

Summary: Both large adsorption capacity and high catalytic activity are essential for water purification through effective degradation of organic pollutants. In this study, a core-shell heterostructure (BTO@TD-COF) was fabricated for efficient adsorption and piezo-photocatalytic degradation of bisphenol A in water. BTO@TD-COF exhibited outstanding piezo-photocatalytic activity due to enhanced carrier separation by the built-in electric field generated in BTO under simultaneous ultrasound and visible-light irradiation. With favorable catalytic and adsorption performance, BTO-3@TD-COF (25 mg) achieved complete degradation of 5 ppm bisphenol A (1000 mL) within 75 min, which was significantly faster than BTO and TD-COF.

Summary: Polyethylene has limitations in HV/UHV power cables due to its low thermal stability and breakdown strength, despite its excellent electrical insulation. A new organic peroxide, Bi25, has been developed to efficiently trigger the crosslinking of polyethylene (Bi25-XLPE). Bi25-XLPE, with void-free nature, higher crosslinking density, and crystallinity, meets the insulation standard for 500 kV power cables. The breakdown strength (up to 61.66 kV/mm) and stability of Bi25-XLPE are confirmed by a constructed 500 kV power cable model using COMSOL.

Summary: In this study, an all-organic S-scheme heterojunction (PDINH/PCN) was obtained by in situ recrystallization of perylene-3, 4, 9, 10-tetracarboxylic diimide (PDINH) on the surface of porous carbon nitride (PCN). This structure enables the light-driven reaction of oxygen and water to produce hydrogen peroxide (H2O2), converting solar energy into green products. The design of a hierarchical porous photocatalyst improved mass transfer, enhanced light absorption, and increased specific surface area. The S-scheme heterojunction formed at the interface of PDINH and PCN facilitated carrier separation and transfer. The H2O2 production rate reached 922.4 lmol g-1h-1, which was 2.6 and 53.3 times higher than that of PCN and PDINH, respectively. Therefore, the all-organic S-scheme heterojunction provides insight for enhancing photocatalytic H2O2 production.

Summary: In this study, self-assembled monolayers (SAMs) were constructed on the surface of Ti3C2 MXene to improve its environmental stability and piezocatalytic activity. The surface-treated Ti3C2 exhibits different lattice parameters and symmetry, leading to an increased polarization. The presence of polar functional groups in SAMs significantly increases the surface potential of Ti3C2, promoting the migration of piezoelectric electrons. Among the different SAMs, Ti3C2/SAMs-NH2 shows the highest piezocatalytic performance, improving the removal of BPA and the production of H-2 by 7 and 1.8 times, respectively, and remains stable under 100% relative humidity for 15 days.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
