Ferroptosis, a recently identified form of non-apoptotic programmed cell death, has attracted significant attention for use in cancer therapies. Jong Seung Kim (金鍾昇) and coworkers summarize recent advances in photo-activated ferroptosis for cancer treatment and describe the underlying mechanisms of those photo-controlled ferroptotic therapies. They also discuss the challenges associated with photo-activated ferroptosis and provide an outlook on future developments of this therapeutic approach.

Owing to its unique physiochemical properties, the difluoromethoxy group is emerging as an important structural motif in pharmaceutical and agrochemical research. Carsten Bolm and coworkers develop mechanochemical difluoromethylation reactions of primary, secondary, and tertiary alcohols. The simplicity of the process and the pOSSibility to purify the products by filtration suggest that these milling events offer opportunities for a more environmentally benign reaction control.

In natural systems, water transport across the cellular plasma membranes is mainly mediated by naturally occurring channel protein aquaporins (AQPs), which leads to a series of important physiological functions, including cell migration. Jun-Li Hou (侯军利), Yunfeng Wang (王云峰), and coworkers report that artificial water channels can induce cell protrusion and cell migration as well, which may provide a way for the treatment of AQP-related diseases.

Formal cross-dimerization of two different strained rings represents an innovative strategy for the creation of specific ring systems that are otherwise inaccessible. However, controlling the reactivity and site-selectivity has been difficult to achieve. Xiao-Song Xue (薛小松), Dongbing Zhao (赵东兵), and coworkers describe a system employing a synergistic Ni/Mg catalyst for site-selective reversal of formal cross-dimerization of benzocyclobutenones and silacyclobutanes. Their approach offers new opportunities for transition metal-catalyzed ring expansion of strained rings toward diverse silacycles.

The incorporation of heteroatoms into carbon nanohoops can significantly lower aromatic stabilization energy and enrich physicochemical properties. Zhaohui Wang (王朝晖) and coworkers have successfully synthesized a novel kind of axially N-embedded quasi-carbon nanohoops using intramolecular or intermolecular nickel-mediated Yamamoto coupling reactions. They speculate that similar strategies may be employed in the design and synthesis of structure-precise segments of graphitic-N-doped single-walled carbon nanotubes.

Jing Liu (刘婧), Yu Li (李昱), Bao-Lian Su (苏宝连), and coworkers report the highly selective photocatalytic conversion of glucose on a holo-symmetrically spherical three-dimensionally ordered macroporous TiO2–CdSe heterojunction photonic crystal structure (s-TCS). The optimized s-TCS-4 photocatalyst displays the highest catalytic performance for glucose oxidation and hydrogen production. This work may help facilitate conversion of biomass into high-value-added chemicals and provide direction for the design of high-performance photocatalysts.

The hole transport layer and perovskite interface are critical for fabricating inverted perovskite solar cells with high efficiency. Wu-Qiang Wu (吴武强) and coworkers introduce a bilateral chemical linker to simultaneously achieve favorable chemical interaction with the hole transport underlayer and form robust coordination bonding with the buried perovskite bottom layer, thus significantly improving the contact affinity, facilitating the hole extraction, well-passivating the interfacial defects, and relieving the nonradiative charge recombination. Their approach results in a champion efficiency of 22.23%.

The close packing effect from high pressure conditions can be useful in creating high-density materials that are suitable for the development of energetic materials. However, high-pressure phases and structures are often not stable at ambient conditions. Qinghua Zhang (张庆华), Yi Wang (王毅), and coworkers propose a novel pressure-induced topochemical polymerization method for the preparation of advanced energetic materials that allows quenching from high pressure.

The structure–performance relationships of the molecularly dispersed heterogenized metallomacrocycles (MDHMs) with π-conjugated heterojunctions is important yet remains poorly understood. Qi-Long Zhu (朱起龙) and coworkers contribute to the understanding of this relationship by designing and synthesizing a series of novel nickel phthalocyanines for CO2 electroreduction to CO. The heterointerfacial effect and self-built microenvironment of the MDHMs are significantly modulated by accurate structural clipping at the molecular level, allowing manipulation of the electrocatalytic performance for CO2-to-CO conversion.

Dynamic polymers with both physical interactions and dynamic covalent bonds are desirable for their superior performance, but it remains difficult to synthesize dry dynamic polymers in an efficient manner. Peng-Fei Cao (曹鹏飞) and coworkers report a novel synthesis of dynamic polymers from a naturally-derived thioctic acid monomer, based on a unique reaction mechanism where a chlorinated solvent can react and stabilize the terminal radical species thus preventing the depolymerization process. The resulting dynamic polymer is highly adhesive and can be used in 3D printing, as well as many other applications.

Mimicking natural photosynthesis to achieve photoreduction of CO2 with H2O for fuels or value-added chemicals has attracted tremendous interest yet remains elusive. Zhimin Liu (刘志敏) and coworkers report temporally separated CO2 photoreduction and H2O photooxidation over redox-active o-hydroxyazo-based conjugated organic polymer films with CO as the sole reduction product. The highly efficient method provides new insights for the design of conjugated organic polymer photocatalysts and artificial photosynthesis.

Spiropyran derivatives are prototype mechanophores with promising applications as molecular sensors because of their changeable structure under external force. However, an understanding of the evolution of the chemical structure under external stimuli remains unclear. Wengui Weng (翁文桂), Wenjing Hong (洪文晶), and coworkers identify the structural origin of the force-induced reaction of spiropyran derivatives using single-molecule conductance measurements and unsupervised clustering algorithm.

Ordered mesoporous noble metals display unique catalytic and electrocatalytic qualities that are distinct from those of traditional nanoparticles. However, the range of mesoporous noble metals remains limited mainly due to single metals and their alloys having random atomic arrangements. Chengbin Zheng (郑成斌), Ben Liu (刘犇), and coworkers report a precise synthesis of novel mesoporous intermetallic noble metal-nonmetal (MI-PtX2) nanoparticles with hierarchical order for highly efficient electrocatalysts.

Plasmonic photocatalysis has long been regarded as a promising strategy for sustainable energy conversion. However, efficient utilization of hot electrons by reactants without surface-seeking groups is difficult to achieve due to the low coordination of reactant molecules with the metal surface. Wei Xie (谢微) and coworkers disclose a new concept of polarized nanocatalysts that mimic chemical polarity at the nanometer scale and enhance hot electron utilization for visible light photocatalysis. With a photo-recycling strategy, they develop a one-pot, hot-electron-driven synthesis of amide compounds, a six-electron reduction from nitro reactants, by using low-cost Ag-TiO2 catalysts.

Flexible electronics are expected to revolutionize personal health management. However, the fabrication of smart sensors with high robustness, reliability, and visible readout remains a significant challenge. Gang He (何刚) and coworkers report stretchable ionogel-containing, viologen-based ionic liquids for strain sensing applications, where the viologen confers the electrochromic and electrofluorochromic properties to the sensors. The devices show strain-induced changes of conductivity and color, enabling strain sensors with simple visible readouts.

The hydrogen oxidation reaction (HOR) in alkaline conditions is of great importance for the application of anion-exchange membrane fuel cells. However, electrocatalysts for the alkaline HOR suffers from unfavorably slow kinetics.

Lead-based organic–inorganic hybrids occupy a niche in the field of optoelectronics owing to exceptional semiconducting properties and potential ferroelasticity. Nevertheless, the possible toxicity of lead restricts their widespread application.
