Abstract Covalent organic frameworks (COFs) are promising for photocatalytic H₂O₂ generation. However, imine‐linked COFs often suffer from poor charge separation and low performance. Therefore, constructing sp 2 carbon‐linked with extended π‐conjugation is very significant in boosting the properties, but their synthesis challenging due to reversibility of C═C bond. Here, two vinylene‐linked COFs: BBT‐ACN COF‐1 COF‐2 designed. To investigate effects different structures on exciton binding energy ( E b ), designed possesses a Donor–Acceptor (D–A) structure electron‐deficient benzobisthiazole (BBT) as acceptor benzotrithiophene donor, while latter holds π‐A pyrene π‐unit BBT acceptor. Both show production activity two‐step 2e − oxygen reduction reaction (ORR). As anticipated, D–A structured exhibits lower value, its H O rate pure water air reaches up 2.50 mmol g⁻¹ h⁻¹, ≈3 times higher than that (0.91 h⁻¹). This study reveals fully ‐carbon‐linked beneficial production, which provides an effective approach designing high‐performance photocatalysts.

The combined application of nanozymes and surface-enhanced Raman scattering (SERS) provides a promising approach to obtain label-free detection. However, developing nanomaterials with both highly efficient enzyme-like activity excellent SERS sensitivity remains huge challenge. Herein, we proposed one-step synthesis Mo2N nanoparticles (NPs) as "two-in-one" substrate, which exhibits peroxidase (POD)-like high activity. Its mimetic POD can catalyze the 3,3′,5,5′-tetramethylbenzidine (TMB) molecule SERS-active oxidized TMB (ox-TMB) efficiency. Furthermore, combining experimental profiling theory, mechanism POD-like enhancement NPs was explored in depth. Benefiting from outstanding properties NPs, versatile platform for indirect detection biomarkers developed based on NPs-catalyzed product ox-TMB, acts signal readout. feasibility this validated using glutathione (GSH) target antigens alpha-fetoprotein antigen (AFP) carcinoembryonic (CEA) representatives small molecules hydroxyl radical (·OH) scavenging effect proteins low cross-section, respectively. limits GSH, AFP, CEA were 0.1 μmol/L, 89.1, 74.6 pg/mL, Significantly, it also showed human serum samples recoveries ranging 96.0 101%. acquired values compared standard electrochemiluminescence method, relative error less than ±7.3.

One of the biggest challenges in biotechnology and medical diagnostics is finding extremely sensitive adaptable biosensors. Since metal-based enzyme-mimetic biocatalysts may lead to biosafety concerns on accumulative toxicity, it essential synthesize metal-free enzyme-mimics with optimal biocatalytic activity superior selectivity. Here, pyridine-bridged covalent organic frameworks (COFs) specific oxidase-like (OXD-like) activities as intelligent artificial enzymes for light-augmented sensing biomarkers are disclosed. Because adjustable bandgaps pyridine structures photocatalytic properties pristine COF structures, exhibit efficient, selective, light-responsive OXD-like activity. Moreover, show tunable detection capabilities, which outperform recently reported state-of-the-art OXD-mimics regarding biosensing efficiency. Notably, exhibits efficient multifaceted diagnostic activity, including low limit (LOD), enables visual assays abundant reducibility biomarkers. It believed that this design will offer unique high-sensitive low-cost colorimetric also provide new insights create highly enzyme-like materials via linkage-modulation strategies future applications.
