An electrodeposited lanthanide MOF thin film as a luminescent sensor for carbonate detection in aqueous solution

Abstract

A luminescent lanthanide MOF-based thin film was fabricated by electrodeposition in an anhydride system and this film can be used as a highly selective sensor for CO32− in aqueous solution.

A polymorphic lanthanide complex as selective Co2+ sensor and luminescent timer

“…Some organic molecules, silver and gold oxide nanoparticles were applied to detect Co 2+ [26][27][28][29][30], and a lanthanide show sensing effect to Zn 2+ , Cd 2+ and Co 2+ at the same time, but it is not a selective Co 2+ sensor [27]. That is, though lanthanide complex had been reported to detect many kinds of ions and molecules [1,3,[31][32][33][34][35][36][37][38][39][40], due to its unique photophysical properties (such as microsecond to millisecond lifetimes, characteristic and narrow emission bands, as well as large Stokes shifts), the selective sensing to Co 2+ is not reported. Therefore, selective and sensitive sensing Co 2+ by luminescent lanthanide complex is urgent and interesting.…”

A luminescent Terbium-Succinate MOF thin film fabricated by electrodeposition for sensing of Cu2+ in aqueous environment

“…(3) The reaction process is more controllable and reproducible due to the nature of electrosynthesis [33]. Through the best of our knowledge, there have been relatively few reports on the Ln-MOF thin films prepared via electrodeposition method [29][30][31].…”

“…Recently our group reported a series of Ln-MOF thin films prepared via cathode electrodeposition under mild conditions [29][30][31]. Under electric field, conductive substances such as conductive glass can functionalize as electron reservoir to induce MOF crystallization [32].…”

Electrosynthesis of Metal–Organic Frameworks: Challenges and Opportunities

“…[76] The electroreduction of NO 3 À at the FTO electrode produced OH À ,w hichc atalysed the hydrolysis of the anhydride groups of BTDA to generate benzophenone-3,3',4,4'-tetracarboxylate (BPTC 4À )a nd its protonation products( HBPTC 3À , H 2 BPTC 2À ,a nd H 3 BPTC À ), depending on the pH of the solution. Eu-HBPTC was formed upon reaction with Eu 3 + and was used as al uminescentsensor for the detection of carbonate.…”
