Synthesis and spectroscopic properties of luminescent tantalum(v)-β-diketonate complexes and their use as optical sensors and the preparation of nanostructured Ta2O5
Abstract:This work proposes a simple and inexpensive method to prepare a new series of β-diketonate-tantalum complexes. The method is based on the use of a [TaF7](2-) solution, as the tantalum precursor, thenoyltrifluoroacetone (TTA), hexafluoroacetylacetone (HFA), and benzoyltrifluoroacetylacetone (BFA) in basic medium; basic pH is achieved by adding urea to the reaction medium. Elemental analysis, H(1)-NMR spectroscopy, potentiometric measurements conducted with a fluorine-selective electrode, conductivity measuremen… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
