Luminol is a well-known electrochemiluminescence (ECL) fluorophore that applied in various sensing fields as an ECL reporter. Regulating the signal off/on transition of offers great opportunities for sensors' design; however, such attempts on luminol are extremely scarce it was regarded to lack promising modification sites. In this study, we developed four derivatives with at amine site and enol systematically explored possible caging strategies regulate emission. The electrochemical corresponding properties reveal analogue etherification group significantly inhibits oxidation behavior almost entirely silences its Inspired by observation, new probe luminol-O-β-d-glucose (Lum-Glc) prepared integrating glucose moieties through ether bond. linkage quenched emission Lum-Glc, which could be cleaved β-glucosidase (β-Glu), enabling "turn-on" determination β-Glu.

Abstract Dual‐band tungsten oxide (WO 3 ) electrochromic films are extensively investigated, yet challenges persist regarding complex fabrication processes and limited cyclic stability. In this paper, a novel approach to prepare graphdiyne quantum dots (GDQDs) doped WO with hexagonal crystal structure, is presented. Structural characterization reveals that the GDQDs/WO possesses coral‐like, loose structure high crystallinity due synergistic modulation of morphology crystallinity. Electrochemical tests confirm unique provides abundant multi‐active sites efficient electrolyte ion channels, which facilitate insertion/extraction promote process. The exhabit impressive performance, rapid swithing (12.6/8.4 s for bleaching/coloration), coloring efficiency (104.78 cm 2 C −1 at 1100 nm), independent dual‐band transmittance changes (ΔT， ΔT 633 nm = 64.54%, 83.52% 1600 79.80%), exceptional stability (remained 95.1% range after 20 000 cycles). characteristics GDQDs lead formation built‐in electric field via charge transfer, optimizes enriches energy level .

Published: Jan. 27, 2025

Contact electrification (CE) spans from atomic to macroscopic scales, facilitating charge transfer between materials upon contact. This interfacial exchange, occurring in solid–solid (S–S) or solid–liquid (S–L) systems, initiates radical generation and chemical reactions, collectively termed contact-electro-chemistry (CE-Chemistry). As an emerging platform for green chemistry, CE-Chemistry facilitates redox, luminescent, synthetic, catalytic reactions without the need external power sources as traditional electrochemistry with noble metal catalysts, significantly reducing energy consumption environmental impact. Despite its broad applicability, mechanistic understanding of remains incomplete. In S–S is primarily driven by surface charges, whether electrons, ions, radicals, on charged solid interfaces. However, a comprehensive theoretical framework yet be established.
