Herein, a barium-based CP (CP-SW5) is rationally designed and synthesized by assembling a conjugated N,O-heterocyclic ligand (HL) with Ba(NO3)2. Single-crystal X-ray diffraction reveals that CP-SW5 forms a rigid two-dimensional supramolecular architecture via Ba‒O coordination, which is assembled into a three-dimensional framework through interlayer hydrogen bonding interactions. This robust structure suppresses the nonradiative decay of triplet excitons and enhances spin–orbit coupling. Characterizations verify its tunable cyan-to-yellow LAL emission, yellow-to-gray photochromism under UV irradiation, and effective phosphorescence-to-photothermal conversion. DFT calculations and experiments confirm that photoinduced electron transfer from the electron-rich terminal to the electron-deficient core group generates HL• radicals, which not only trigger photochromism but also enhance self-absorption to boost photothermal conversion efficiency. This work provides a feasible strategy for constructing multifunctional CPs with integrated photofunctional properties, showing tremendous potential in intelligent anticounterfeiting and information security applications.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 8","pages":"2274–2282"},"PeriodicalIF":8.6,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148682554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Partial dissolution of CSSK and structural bridging by NDF enable the formation of an interconnected hybrid network with enhanced interfacial coupling. pH modulation governs both interfacial interactions and pore architecture: alkaline conditions promote homogeneous silica deposition and stronger bonding, whereas acidic conditions induce a denser, microporous structure. The resulting composites exhibit improved mechanical robustness and reduced dust release. All samples show superinsulating behavior (λ < 26 mW m−1 K−1), with thermal transport determined by the interplay between the pore structure and density.

Electrochemical characterization showed that Mn-to-Fe substitution significantly improved capacity retention, while preserving high initial capacity. Operando and ex situ diffraction experiments revealed that both materials transition from a rhombohedral to a distorted phase during charge, with higher bond distance anisotropy in the Mn-PW. Finally, the substituted compound demonstrated excellent cycling stability in full cells versus hard carbon, retaining nearly 84% of capacity after 400 cycles at 1 C.

Herein, we present atomically dispersed zinc−phosphorus (Zn−P) catalytic pairs (CPs) anchored on acid-resistant carbon nanosheets (Zn−P/CNS) that display greatly enhanced multienzyme-like activities, particularly for superoxide radical dismutation and hydrogen peroxide decomposition. Density functional theory reveals that P primarily serves as an additional catalytic site to facilitate substrate binding and intermediate stabilization, while also modulating the local electronic structure of Zn and aiding proton transfer, thereby lowering energy barriers in the multistep redox pathways.

Above 4 GPa, we observe a reduction of the exciton redshift rate in the chiral samples compared to the racemate, a behavior paralleling the evolution of the N−H vibrational modes in the infrared spectrum. We hypothesize that, at 4 GPa, the asymmetric N−H⋯I bonding network in the chiral systems reaches the limit of its buffering capability. Further compression is then accommodated through octahedral distortion, enhancing the chiral character of the inorganic sublattice. The corresponding modification of the octahedral angles reduces Pb-s/I-p orbital coupling, explaining the decrease in the exciton redshift rate. Conversely, the symmetric N−H⋯I bonds in the racemate prove more effective at accommodating compression without altering the octahedral orientation.

In tritopic triphenylene-based frameworks, square-planar Ni nodes stabilize the quartet state of linker, which couples via superexchange to generate double kagome bands. In contrast, Jahn–Teller distortion at Cu centers favors the doublet state of linker, suppresses kagome-type dispersion, and drives the system toward open-gap honeycomb bands. Extension to tetratopic porphyrin-based frameworks confirms analogous structure–spin interplay in 4-fold lattices. Comparison between 3-fold and 4-fold systems shows that stronger superexchange broadens Dirac bandwidths and enhances in-plane transport.

This nanocomposite integrates the advantages of both components, consisting of alternately restacked unilamellar MnO2 and rGO nanosheets with molecular-scale homogeneity, which affords high electrical conductivity, a large surface area with abundant active sites, and rapid Zn2+ migration. As a result, the ZIB assembled with the MnO2/rGO nanocomposite delivered a specific capacity of 228 mAh g−1 at 50 mA g−1, far exceeding that of individual MnO2 and rGO, thereby demonstrating that composite construction can significantly enhance the Zn2+ storage abilities of MnO2 nanosheets.
