Summary: The article describes a method for remotely manipulating non-photoresponsive chiral plasmonic molecules (CPMs) using light, inducing DNA triplex link formation through a photoacid medium, resulting in spatial reconfiguration of CPMs. The overall chirality change depends on the fraction of CPMs undergoing reconfiguration, which is related to the intensity of incident light.

Summary: Indazole metastable-state photoacids have been used to regulate the local pH of tumor and brain. The photo reaction of indazole photoacid is different from merocyanine photoacid in water. A high water-soluble indazole photoacid was designed and synthesized, which generates a quinoidal cis-conformer instead of the spiro conformer in water. The cis-conformer possesses higher acidity due to the unusual quinoidal structure.

Summary: Solution-processable all-inorganic CsPbI3-xBrx perovskite is a promising material for pure red light-emitting diodes. However, defects in the perovskite significantly reduce device efficiency and stability. In this study, Ruddlesden-Popper planar defects inside the CsPbI3-xBrx perovskite film were identified as the primary form of defects, caused by inhomogeneous halogen ion distribution and lattice strain. A stepwise metastable phase crystallization strategy was developed to minimize the lattice strain, resulting in defect-free CsPbI(3-x)Brx films with improved radiative recombination, narrower emission band, and enhanced spectral stability. By using these high-quality films, spectrally stable pure red perovskite light-emitting diodes were fabricated, achieving an external quantum efficiency of 17.8% and a brightness of 9000 candela meter(-2) with color coordinates required by Rec. 2020.

Summary: Four open-form configurational isomers were identified for an unsubstituted metastable-state photoacid (mPAH) of the tricyanofuran (TCF) type in solution, and the molecule can freely interconvert between these isomers. This work provides an important foundation for further studies on the thermal and excited-state isomerization processes, as well as the substituent effect.

Summary: One of the challenges in current DAC technologies is the high energy cost for sorbent regeneration and CO2 release, making large-scale deployment economically unfeasible. In this study, a photochemically-driven approach using a unique photoacid was developed for CO2 release in DAC systems. The results showed that under light irradiation, a significant conversion of total inorganic carbon to CO2 was achieved, confirming the feasibility of energy-efficient CO2 release using light instead of heat.

Summary: Photoresponsive supramolecular hydrogels based on the host-guest interaction between cyclodextrin and azobenzene have been widely used in biological applications. However, most of these hydrogels are UV-responsive and have limitations such as poor tissue penetrability and potential cytotoxicity. In this study, a red-light-responsive semiconvertible hydrogel was developed using tetra-ortho-methoxy-substituted azobenzene and hyaluronic acid. The hydrogel exhibited reversible mechanical and structural dynamics under alternating irradiation, avoiding complete gel-sol transition. These hydrogels show potential advantages in tissue engineering, especially for the regeneration of functional multi-tissue complex.

Summary: Photoresponsive polymers using red light as the excitation source were designed and prepared, exhibiting high water stability and controlled drug release. These polymers self-assembled into micellar nanovectors, encapsulating a hydrophobic model drug within the micellar core. Irradiation with 660 nm LED light led to the release of the drug, avoiding the problems associated with UV light in biological tissues and promoting practical applications of photoresponsive polymer nanomedicines.
