  "abstract": "Multiple technologies have been developed to reconcile the trade-off between sensitivity and portability, which is a persistent fundamental challenge in chemical sensing. Among them, electrochemiluminescence (ECL) has the advantages of simple device configuration and outstanding sensitivity based on the transduction of electrochemical signals into optical readouts. However, this is based on multi-step interfacial electron transfer, wherein the concomitant efficiency losses and areadependent signal intensity inherently constitute the primary limitations. Herein, a novel photochargeable wireless ECL (PC-Wireless-ECL) system is established based on a bifunctional carbon nitride (CN). This strategy boosts the ECL signal intensity by eliminating the dependence on the electrode dimensions and decoupling the excitation and emission processes temporally. By constructing portable bifunctional CN vials coupled with a miniaturized light intensity sensor, this system revolutionizes the conventional ECL measurement paradigm and realizes on-site, rapid, and highly sensitive screening of water toxicity, thereby offering a new strategy for next-generation in-field analytical technologies.",
