Abstract:
Solid-state electrochemiluminescence (ECL) has drawn increasing attention due to its advantages over solution-phase ECL, such as reducing the consumption of expensive reagents and enhancing the ECL signal. Herein we report a ruthenium(ii)-polypyridyl doped zirconium(iv) metal-organic framework (MOF) film, UiO-67-Ru@FTO, for solid-state electrochemiluminescence. With tripropylamine (TPA) as a coreactant, UiO-67-Ru@FTO exhibited high ECL intensity and good stability. A linear relationship was found between the ECL intensity and TPA concentration in a wide range of 0.04-20 mM. Additionally, UiO-67-Ru@FTO was successfully used for dopamine detection, implying its great potential in real-life applications.
