“…The presence of an intense low-angle diffraction, close to seven 2θ/degrees (interplanar spacing d ∼ 12 Å), is also repeated in all the synthesized coordination compounds. These results are similar to the behavior shown by MOFs [38] and corroborate those described in the literature [26,28,29,32].…”

Porous crystalline luminescent polymer compounds have attracted huge interest due to their supramolecular structures, aesthetically attractive structural topologies and potentialities for innovative technological applications. However, wet route precipitation or hydro/solvothermal methods may lead to the formation of highly insoluble porous coordination networks, as is true of europium diphenylphosphinates -[Eu(dpp) 3 ] n . The aim of this work was to study the optical behavior and its relation to the structure of [Eu(dpp) 3 ] n complexes obtained through different synthetic approaches by precipitation: wet route (WRS), ultrasound-assisted wet route (U-WRS), modulator-assisted wet route (M-WRS) and wet route synthesis with solvothermal treatment (S-WRS). These methodologies allowed to synthetize crystalline materials in which both chelate and bridged coordination modes coexist, and they were efficient for obtaining stick-shaped 1D1 nanostructured materials with well-defined optical properties. Changes in precipitation kinetics and crystalline phases formation rate led to a distribution of Eu 3+ ions in higher symmetry sites (HSS). S-WRS, transforming part of the less symmetrical sites into HSS, provided a better ordering of [Eu(dpp) 3 ] n . Furthermore, this is the first report of two or more symmetry sites for Eu 3+ in a pure [Eu(dpp) 3 ] n matrix.

“…In a previous work we have described the luminescence properties of Eu(DPP) 3 [6], Gd 1−x Eu x (DPP) 3 [7], and La 1−x Eu x (DPP) 3 [8], with x varying from 0.50 to 0.99 (DPP, the anion of the diphenylphosphinic acid). In the present paper, we describe the synthesis, characterization and luminescent spectroscopic properties of the complexes Y 1−x Eu x (DPP) 3 , with x varying from 0 to 50% in molar concentration of Eu 3+ .…”

The luminescent nanoparticles with Eu(III) ions are reported. Standard nanoparticles are prepared by the reaction of europium chloride with dpp (diphenylphospinic acid) joint ligands. The size-controlled nanoparticles are synthesized by the reaction of Eu(hfa)3(H2O)2 (hfa: hexafluoroacetylacetonate) with bidentate dpbp ligands (dpbp: 4,4'-bis(diphenylphosphoryl)biphenyl) and monodentate ligands (TPPO: triphenylphosphine oxide). Their particle sizes were characterized using TEM and dynamic light scattering (DLS) measurements. Their luminescence properties were estimated by the emission spectra and lifetimes.
