Electrochemiluminescence (ECL) of a boron-dipyrromethene dye (BDY) in the presence of tri-n-propylamine as a co-reactant was found to be efficient. The ECL of BDY showed a unique peak wavelength of 707 nm, indicative of the intermolecular electronic transition mechanism.

Electrochemiluminescence (ECL) combines electrochemical redox processes with photochemical light emission, offering exceptional sensitivity, spatial control, and stability. Widely applied in biosensing, medical diagnostics, and environmental monitoring, its efficiency often depends on advanced catalytic materials. Single-atom catalysts (SACs), featuring isolated metal atoms dispersed on a support, have emerged as promising candidates due to their unique electronic structures, high atom utilization, and tunable catalytic properties.

For optimal energy transfer in self-luminous lanthanide metal-organic frameworks (Ln-MOFs), the energy of the lowest triplet excited state must align with ideal energy levels. Failure to meet this condition can lead to reverse energy transfer, reducing luminous efficiency. In this study, we developed a mixed-ligand MOF, Eu-TCPP-BOP, which exists as an ECL self-enhancing luminophore.

Porphyrins, known for their exceptional photoelectrochemical properties and high luminescence, are promising candidates for electrochemiluminescence (ECL) applications. However, their tendency to aggregate in aqueous solutions due to π-π stacking leads to luminescence quenching and reduced efficiency. To address this, we developed a "coordination disaggregation-induced enhancement" strategy, utilizing metal-organic frameworks (MOFs) as stable platforms for immobilizing porphyrin.

Nitrogen doping enhances the catalytic performance of carbon-based metal-free electrocatalysts (C-MFECs) by modifying their chemical environment. Understanding the structure-catalytic activity relationship of nitrogen-doped (N-doped) C-MFECs is crucial for elucidating catalytic mechanisms and designing efficient electrocatalysts, but it remains challenging. Recently, reactive oxygen species (ROS)-triggered electrochemiluminescence (ECL) has shown great potential for uncovering these mechanisms due to its simple setup, low background signal, wide dynamic range, and high sensitivity.

In this study, a signal amplification strategy was developed, which tris (2, 2'-bipyridyl) ruthenium (II) (Ru(bpy)) was incorporated as a guest molecule into the preparation system of lanthanide-based metal-organic framework (MOF). This strategy relied on strong electrostatic interactions and coordination competition to influence the growth process of the MOF, resulting in the firm immobilization of Ru(bpy) within the MOF structure. The spatial confinement effect of the MOF effectively improved the efficiency of electron transfer in the electrochemiluminescence (ECL) reaction.
