“…For instance, Zhang’s group prepared the M6-MOF with two links of 1,3,6,8-tetra (4′-carboxyphenyl) pyrene (TABPy) and 5,10,15,20-tetra(4-carboxyphenyl)porphyrin (TCPP), where TCPP facilitated electron transfer to enhance the ECL emission of TABPy . Wei’s team developed the TCPP@UiO-66-NH 2 MOF, where UiO-66-NH 2 stabilized the ECL of TCPP and provided –NH 2 for binding to antigens and antibodies . Accordingly, integrating two different ligands with ECL characteristics into a MOF is an excellent strategy to develop a single luminophore with different ECL emission properties.…”

This study developed a new zirconium metal− organic framework (MOF) luminophore named Zr-DPA@TCPP with dual-emission electrochemiluminescence (ECL) characteristics at a resolved potential. First, Zr-DPA@TCPP with a core− shell structure was effectively synthesized through the self-assembly of 9,10-di(p-carboxyphenyl)anthracene (DPA) and 5,10,15,20tetra(4-carboxyphenyl)porphyrin (TCPP) as the respective organic ligands and the Zr cluster as the metal node. The reasonable integration of the two organic ligands DPA and TCPP with ECL properties into a single monomer, Zr-DPA@TCPP, successfully exhibited synchronous anodic and cathodic ECL signals. Besides, due to the impressively unique property of ferrocene (Fc), which can quench the anodic ECL but cannot affect the cathodic ECL signal, the ratiometric ECL biosensor was cleverly designed by using the cathode signal as an internal reference. Thus, combined with DNA recycle amplification reactions, the ECL biosensor realized sensitive ratiometric detection of HPV-16 DNA with the linear range of 1 fM−100 pM and the limit of detection (LOD) of 596 aM. The distinctive dual-emission properties of Zr-DPA@TCPP provided a new idea for the development of ECL luminophores and opened up an innovative avenue of fabricating the ratiometric ECL platform.

In recent years, there has been an increasing research focus on the luminol–H2O electrochemiluminescence (ECL) system due to its ability to address the instability and toxicity of H2O2, which are common issues associated with the conventional luminol–H2O2 ECL system. To enhance the ECL efficiency of the luminol–H2O system, researchers have developed electrocatalytic materials with exceptional oxygen evolution reaction (OER) properties to facilitate water electrolysis into O2 to produce reactive oxygen species (ROS) and act as co‐reactant promoters. However, most of these materials are characterized by their nanoscale or microscale dimensions, resulting in relatively large sizes and low specific surface areas, which hinder the application of the luminol–H2O system. To address this challenge, nickel molybdate sub‐1 nm nanowires (NiMoO4 S1 NWs) with a large specific surface area is synthesized that can offer many active sites to enhance the performance of the OER to boost the ECL of luminol. This study demonstrates that the large amount of ROS generated by the OER of NiMoO4 S1 NWs play a crucial role in enhancing the ECL intensity of luminol. Finally, a NiMoO4 S1 NWs‐based ECL biosensor for the highly sensitive detection of the nucleocapsid proteins of SARS‐CoV‐2 is successfully constructed.
