Structural Isomerism of Covalent Organic Frameworks Causing Different Electrochemiluminescence Effects and Its Application for the Detection of Arsenic

“…To enrich the connotation of the molecular design of the ECL-COF, our group took the lead in employing electron donors (D) and acceptors (A) as building units of COFs and linked them through conjugated CC bonds. The D–A structure inspired the intramolecular charge transfer, thus arousing the ECL from non-ECL monomers; furthermore, the ECL performance can be regulated through the reasonable design of building units. , Despite that significant progress has been created in structure–function relationship under the perspective of monomer and connection types, it still demands further exploration to promote the application of COFs in the ECL field.…”

Linkage in COF scaffolds is a non-negligible position, which prospers the properties of COFs, attributing to its influence in the π-conjugated range, planarity, and stability.…”

One-Dimensional Covalent Organic Framework with Improved Charge Transfer for Enhanced Electrochemiluminescence

“…Nevertheless, due to poor stability and low ECL efficiency (Φ ECL ), even trace oxygen or water may induce aggregation in aqueous solutions, resulting in the quenching of ECL. 11 Covalent organic frameworks (COFs) are crystalline polymers containing organic units linked by covalent bonds, with potemtial applications in catalysis, optoelectronics, energy storage, pollutant removal, and drug delivery. 12,13 The topologies of COFs can be precisely regulated by selecting and designing appropriate organic building blocks and linkages (e.g., skeleton, pore size, and chemical properties).…”

“…ECL has distinct characteristics of precise control of reaction kinetics, ease of miniaturization, and absence of excited light, , with wide applications in biological immune analysis, , medical diagnosis, food safety, and environmental monitoring. − Recently, a variety of organic ECL systems with the integration of polycyclic hydrocarbons and organic dyes have been constructed with the characteristics of high activity, nonmetal, and fine-tuning emission wavelength. Nevertheless, due to poor stability and low ECL efficiency (Φ ECL ), even trace oxygen or water may induce aggregation in aqueous solutions, resulting in the quenching of ECL …”
