Synthesis, crystal structure and fluorescent properties of a novel europium tetracarboxylate
Lanthanide organic frameworks (LnOFs) are promising optical materials. The design and synthesis of new LnOFs with novel crystal structure and fluorescent properties are highly desirable. In this work, one new Europium(III) carboxylate, namely, [Eu(HTTCA)(H2O)2]·2H2O (TTCA-Eu), has been successfully synthesized from a tetracarboxylate ligand, H4TTCA = [1,1′:2′,1″-terphenyl]-4,4′,4″,5-tetracarboxylic acid. It is revealed that TTCA-Eu possesses a three-dimensional crystal structure with rhombus channel about 7.46 × 21.26 Å2 running along c-direction. TTCA-Eu displays typical Eu(III) emissions in the red region and shows a fluorescence quenching response toward dinotefuran. It can be used as fluorescence sensor of dinotefuran in the range of 0–30 μM with high selectivity, signifying its potential application as dinotefuran sensor.
期刊介绍：
Launched in January 1998, Inorganic Chemistry Communications is an international journal dedicated to the rapid publication of short communications in the major areas of inorganic, organometallic and supramolecular chemistry. Topics include synthetic and reaction chemistry, kinetics and mechanisms of reactions, bioinorganic chemistry, photochemistry and the use of metal and organometallic compounds in stoichiometric and catalytic synthesis or organic compounds.
