Summary: In recent years, dyads in which molecular donor and acceptor moieties are chemically linked by a bridging ligand have shown promise in light-driven catalysis. The modular structure, control-lable donor-acceptor distance, and light-driven charge transfer abilities make these systems attractive for light-driven charge-transfer reactions and light-driven redox catalysis. This review discusses the role of 1,2,3-triazole bridging motif in driving electron transfer in triazole-bridged donor-acceptor dyads upon photoexcitation, and how the structural and electronic properties of the bridge influence charge separation and recombination rates. Criteria for designing dyads with different electron transfer properties are also derived.

Summary: The experimental results show that for Fe-Fe series compounds, decreasing the electron donating ability of the ligand on the acceptor fragment or increasing the electron donating ability on the donor fragment is conducive to MMCT. For Ru-Fe series compounds, increasing the electron donating ability on the donor fragment results in a gradual decrease in the energy of MMCT. By changing the metal center of the donor fragment from Fe-Fe to Ru-Fe series compounds, the energy of MMCT increases. All six mixed-valence compounds belong to Class II systems, as confirmed by TDDFT/DFT calculations.

Summary: In this review, we discuss the strategy of donor-acceptor interactions for capturing and activating carbon dioxide. We categorize the systems into metal-free examples, main group-transition metal combinations, and transition metal heterobimetallic complexes, and summarize one hundred compounds with cooperative CO2 activation by donor-acceptor interactions. This perspective provides an overview of the wide variety of structural motifs and assesses the limitations and prospects for developing catalytic protocols for CO2 functionalization.

Summary: The study investigates the photoinduced electron transfer in newly assembled dyads formed via metal-ligand axial coordination of BODIPY(Im)2 and zinc tetrapyrroles in non-coordinating o-dichlorobenzene. Results show that the electron acceptor properties of bis(styryl)BODIPY in donor-acceptor conjugates are significant, with PET being thermodynamically unfavorable in the ZnP-bearing complex but possible in ZnPc- and ZnNc-bearing complexes when selectively exciting the zinc tetrapyrrole. Efficient PET is observed in the latter two dyads based on femtosecond transient absorption studies, with spectroscopic identification of the electron transfer products.

Summary: Mechanophores are stress-sensitive molecules that undergo productive chemical transformations under mechanical force. A new platform has been introduced to achieve mechanically gated multicolour chromogenic reactivity. This platform is based on an activated furan precursor, which, when mechanochemically activated, generates a diverse range of color variations. This system has been applied to create a complex multicolour composite image through localized compression and reaction with different secondary amines.

Summary: Merocyanine dyes are of great interest due to their nonlinear optical properties and solvatochromism. In this study, the excited state dynamics of a merocyanine dye known as HB194 were investigated, revealing solvent-dependent charge transfer dynamics. The excited state decays in different solvents showed multi-exponential components, with polar solvents inducing conformationally relaxed intramolecular charge transfer states and nonpolar solvents exhibiting solvent-stabilized ICT states. An anomalously red-shifted emission was observed in ethylene glycol, which was attributed to the presence of molecular dimers. This work emphasizes the importance of gaining molecular-level insight into system-solvent interactions for designing next-generation merocyanine-based solvatochromic dyes.

Summary: Air-stable amine- and phosphine-boranes have been discovered as donors to form photoactive electron-donor-acceptor (EDA) complexes with pyridinium acceptor. The EDA complex, upon irradiation, undergoes intra-complex single electron transfer without the need for external photosensitizer and radical initiator, leading to the formation of a boron-centered radical for dehydrogenative borylation. DFT calculations suggest that the deprotonation of the Wheland-like radical intermediate, rather than its generation, determines the good ortho-selectivity. Various alpha-borylated pyridine derivatives can be easily synthesized with good functional group tolerance.

Summary: This study proposes a novel AuNC-based ECL sensing platform and explores the regulation mechanism of electron transfer on ECL. By investigating the ECL quenching effect of OM-AuNCs under the influence of Cu2+, it is found that the ECL intensity of OM-AuNCs is affected by the electron transfer process, enabling sensitive detection of Cu2+ in a low concentration range without the need for amplification techniques. This study enriches the application of ET-mediated ECL and promotes a more rational design of ECL sensors.

Summary: This study presented a novel class of luminogen called 6-Aza-2-thiothymine-decorated gold nanoclusters (ATT-AuNCs) with aggregation-induced emission property, which demonstrated potent antimicrobial activity against methicillin-resistant Staphylococcus aureus (MRSA). By generating reactive oxygen species (ROS) and altering the expression of multiple target proteins in MRSA cells, ATT-AuNCs effectively eliminated MRSA. Additionally, ATT-AuNCs could serve as a wound-healing agent. Therefore, ATT-AuNCs are considered robust antimicrobial aggregation-induced emission luminogens (AIEgens) capable of targeting multiple pathways to eliminate drug-resistant bacteria.

Summary: In this study, an energy level engineering strategy was proposed to regulate the electrochemiluminescence (ECL) performance using ligand-protected gold nanoclusters (AuNCs) as luminophores and N,N-diisopropylethylamine (DIPEA) as a coreactant. The energy level matching between the AuNCs and DIPEA effectively promoted electron transfer reactions, improving excitation efficiency and reducing trigger potential. The narrow bandgap of the AuNCs further enhanced emission efficiency. The developed theory was successfully applied to design a highly stable near-infrared ECL system with low trigger potential.
