Summary: In this study, a universal Cu(I) center was coupled with multiple strong visible-light-absorbing antennas to overcome the energy level limitations of current noble-metal complexes, resulting in the development of a broadband and strong visible-light-absorbing nonprecious complex. The systematic investigations demonstrated that this complex enables efficient intermolecular electron/energy transfer and exhibits outstanding performance for both energy- and electron-transfer reactions. These findings open up new possibilities for the development of efficient earth-abundant photosensitizers for boosting photosynthesis.

Summary: Conjugated polymer photocatalysts with D-A structure were developed, and the band gap of the polymers can be tuned by adjusting the number of fused-thiophene rings. Increasing the number of thiophene rings extends the visible light absorption range. The optimized molecular structure facilitates efficient photocatalytic hydrogen and oxygen evolution.

Summary: In this study, two organic-metal photocatalysts, P-L (PtCl2 and PdCl(2)), were proposed. X-ray photoelectron spectroscopy showed that their binding energies match precisely the binding energies of the respective M-(bpy)-Cl-2 complexes. Cyclic voltammetry measurements of the complexes displayed additional reduction potentials upon metal insertion. Light-driven catalysis demonstrated that both compounds are catalytically active, with P-Pt outcompeting P-Pd with a TON of 186 over 48 h in the presence of ascorbic acid (P-Pd: 50). Time-resolved spectroscopy on P-L and P-Pt yields insights into the light-induced intramolecular processes, and the role of different excitation states in the catalytic process.

Summary: Pure g-C3N4 (PCN) prepared by traditional thermal condensation polymerization has low polymerization of heptazine ring chains and a large number of charge recombination centers, resulting in undesirable photocatalytic performance. By thermal treatment with ammonium oxalate monohydrate, highly dispersed porous g-C3N4 nanosheets were produced, and the integrity of their in-plane heptazine ring chains was successfully improved without introducing heteroatoms. The obtained samples exhibited acceptable stability and photocatalytic activity, with a hydrogen reduction rate 11.2 times higher than that of PCN in the absence of the Pt co-catalyst.

Summary: Polymer micelles are potential materials for efficient catalysis in their unique nanospaces. However, the design of polymer micelle-based nanoreactors for dual photocatalysis, involving both a photocatalyst and another catalyst, is still limited due to the lack of molecular insight. In this study, we investigated the cooperation between a photocatalyst and a hydrogen evolution catalyst immobilized within the shell of polymer micelle-based nanoreactors. Our results suggest the existence of fluctuated and contacted pairs of the two catalysts within the nanoreactors, and the reaction rates were influenced by molecular crowding within the shell. This study provides a basis for developing efficient polymer micelle-based nanoreactors for dual photocatalysis.

Summary: A Dion-Jacobson phase calcium niobate was synthesized using both a flux method and solid-state reaction. Chemical exfoliation of the proton-exchanged niobate produced colloidal Ca2Nb3O10- nanosheets for dye-sensitized H-2 evolution, with flux-based nanosheets showing higher activity compared to those synthesized by solid-state reaction, particularly in water splitting systems. The improved H-2 evolution properties of the flux-derived nanosheets could be attributed to more efficient electron transfer pathways demonstrated by transient absorption spectroscopy.

Summary: By utilizing density functional theory (DFT) analysis, a series of electron donor-acceptor (D-A) conjugated organic polymers were designed and synthesized. These polymers showed high efficiency in photocatalytic CO2 reduction under visible light irradiation. One of the polymers, derived from anthraquinone and triphenylamine, exhibited a high rate and selectivity in producing CO without the need for sacrificial reductants. The selectivity could be attributed to the intrinsic hydrophobicity of the photocatalyst.

Summary: Our study demonstrates the concept that single excitation of the two-electron reduced forms of perylene diimides (PDIs) with green photons can produce excited states with similar or greater reducing power than the shorter-lived excited states of PDI radical monoanions. By performing multi-electron reduction of a photocatalyst with a sacrificial reagent before irradiation with low-energy photons, we can generate highly reactive excited states for photocatalytic reactions.

Summary: We reported here the development of a heterobimetallic NiFe molecular platform to investigate the synergistic effect of NiFe in water oxidation catalysis. Compared to homonuclear bimetallic compounds (NiNi and FeFe), the NiFe complex exhibited significant catalytic activity in water oxidation. Mechanistic studies showed that this enhanced activity is attributed to the effective promotion of O-O bond formation by NiFe synergy. The formation of Ni-III(mu-O)Fe-IV=O intermediate is the key step for O-O bond formation through intramolecular oxyl-oxo coupling between bridged O radical and terminal Fe-IV=O moiety.

Summary: This study reports a new approach to achieve control over blue-to-UV upconversion by tethering a naphthalene unit to a cyclometalated iridium-(III) complex, providing a better option for photochemical applications. The bichromophore demonstrated a higher triplet energy and longer lifetime compared to the parent complex. The threshold for blue-to-UV upconversion to shift from quadratic to linear excitation power dependence was consistently lower with the bichromophore. Additionally, the bichromophore showed long-term stability under blue irradiation and successfully drove chemical reactions that normally require UV light.

Summary: To combat viral infectious diseases efficiently, it is crucial to develop broadly applicable countermeasures. Elaborating the relationship between antiviral agents and viruses can lead to the development of efficient antiviral systems. This study used conjugated polymer-based photodynamic therapy to inhibit RNA virus infections and assessed antiviral efficiency using a pseudotyped virus composed of SARS-CoV-2 envelope and luciferase RNA genome. Different cationic CPs showed varying photoinactivation effects, with PPV and PMNT exhibiting highly efficient photoinactivation derived from the complete degradation of spike proteins, nucleocapsid proteins, and nucleic acids of SARS-CoV-2.

Summary: The process of water oxidation is a challenging task in the development of artificial photosynthetic systems. The use of redox-active ligands in conjunction with metals has been recognized as an effective approach for managing this process. However, the detailed mechanisms of how the electronic effect of these ligands affects the reactivity of the catalytic centers are still unclear. In this study, the electronic effect of a series of mononuclear Ru complexes with redox-active ligands was investigated, and it was found that the ligand-centered oxidation plays a crucial role in the water oxidation process. This study provides important insights into the role of redox-active ligands in controlling the water oxidation process.
