Here, we demonstrate a topological laser fabricated via single-step nanoimprinting onto colloidal perovskite nanocrystals. This laser supports multiple higher-order topological corner states (HOTCS), with the topological protection provided by the structure effectively mitigating fabrication imperfections that typically arise during nanoimprinting. This robustness enables the reliable detection of these HOTCS, a feat that is particularly challenging to achieve within the visible spectrum.

However, simultaneously achieving substrate coverage, interfacial stability, and energy level alignment remains challenging. Herein, guided by the “like dissolves like” principle and the amphiphilic nature of perovskite precursors, we report a fluorinated amphiphilic SAM material, (2-(4-(bis(3-fluoro-4-methoxyphenyl)amino)phenyl)-1-cyanovinyl) phosphonic acid (MPA-CPA-F). The molecule integrates a hydrophobic, electron-donating fluorine/methoxy-substituted triphenylamine core and a hydrophilic cyanophosphonic acid anchor via a rigid π-conjugated vinyl bridge. This fluorinated amphiphilic design facilitates high-quality perovskite deposition by ensuring robust substrate anchoring and superwetting behavior toward perovskite precursors. Notably, MPA-CPA-F coordinates with uncoordinated Pb<sup>2+</sup> and forms hydrogen bonds with organic cations, effectively passivating interfacial defects, while its large dipole moment optimizes energy level alignment. These synergistic effects significantly suppress non-radiative recombination and accelerate hole extraction, yielding a champion power conversion efficiency (PCE) of 25.88% alongside excellent humidity and thermal stability.

To address this, we introduce atomically anchored Pt–N sites as bidirectional electron highways into the π-conjugated TpTz-COF, which features an inherently heterogeneous electronic structure. Through robust Pt–N coordination anchoring, these atomic-scale clusters reconfigure the charge dynamics of the matrix by establishing bidirectional charge-transport pathways. This architecture simultaneously harvests photogenerated electrons from both donor and acceptor moieties while effectively suppressing charge carrier recombination. The resulting heterostructure achieves a remarkable apparent quantum efficiency (80.72%) under 420-nm irradiation. Such a high value results from the low work function (<em>Φ</em> = 4.306 eV) of Pt driving directional electron migration, and the optimized Gibbs free energy of hydrogen absorption (Δ<em>G</em><sub>H*</sub> = −0.13 eV) accelerates the catalytic turnover. Crucially, covalent Pt–N interfacial bonds endow the material with exceptional operational stability across extreme pH conditions and during 22-d cycling tests, resolving long-standing durability issues in metal–organic hybrids. This innovative approach employs Pt clusters as active charge-directing centers rather than mere catalytic sites, establishing a paradigm-shifting principle for the design of next-generation photocatalysts that extends beyond the optimization of intrinsic material properties.</div></div>","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":"71 8","pages":"Pages 1984-1992"},"PeriodicalIF":21.1,"publicationDate":"2026-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147508539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Landau levels consist of a series of degenerate states of Landau modes, making them a promising platform for large-capacity information processing. However, to date, exploiting the high-order Landau modes and controlling their spatial distributions has remained elusive. Here, we propose to construct magnetic fields, electric fields, and imaginary momentum simultaneously to reshape high-order Landau modes in non-Hermitian systems. By building a non-Hermitian electric circuit platform, we experimentally realize pseudomagnetic fields via inhomogeneous coupling and pseudoelectric fields via a gradient on-site potential, while simultaneously introducing an imaginary momentum via non-reciprocal coupling. We directly observe multi-frequency single-peak localization of high-order Landau modes. Our work provides a universal method for manipulating high-order Landau modes and exploring applications in non-Hermitian systems, such as frequency multiplexing and wave packet reshaping.</div></div>","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":"71 8","pages":"Pages 1949-1956"},"PeriodicalIF":21.1,"publicationDate":"2026-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147508556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
