High-performance luminescent materials are indispensable
for advancing
the development of electrochemiluminescence (ECL). In this work, a
series of organic small-molecule ECL materials viologens were rationally
designed and synthesized, which possess favorable redox activity,
superior water solubility, and outstanding luminous efficiency. All
prepared samples generate intense annihilation and coreactant-promoted
ECL signals. Experimental and theoretical investigations demonstrate
that side-substituted groups can greatly modulate the ECL properties.
Among them, viologen Nap-Py-2PF<sub>6</sub> with a large conjugated
framework delivers the highest luminous efficiency, up to 74.36%.
Relying on the facile complexation between the probe and uric acid,
the established sensing strategy realized ultrasensitive detection
of uric acid in real samples. This study pioneers the application
of viologen derivatives in ECL sensing and explores their favorable
luminescence properties, offering an effective new route for uric
acid quantitative analysis.
