Eu-Doped layered yttrium hydroxides sensitized by a series of benzenedicarboxylate and sulphobenzoate anions

Abstract

A series of new Eu-doped layered yttrium hydroxides intercalated with various organic dianions having similar molecular structure (dicarboxylates and sulphobenzoates) were synthesized.

High-Entropy Layered Rare Earth Hydroxides

“…Four- and seven-cationic samples possessed the same particle size as high-entropy layered hydroxides (see Figure S4). The microstructure of the samples was typical of the layered hydroxides obtained by high-temperature hydrolysis in the presence of hexamethylenetetramine. − …”

The first amorphous and crystalline yttrium lactate: synthesis and structural features

“…19 Interestingly, at nearly neutral pH ($6) and under mild hydrothermal conditions, the interaction of rare earth ions with mono-or bidentate ligands can result in polynuclear coordination compounds, which are oen regarded as layered rare earth hydroxides (LRHs) comprising innite positively charged 2D layers of [RE(OH) 3Àn ] n+ bonded by the ligands into laminate structures. [61][62][63] These ion-exchangeable and exfoliatable substances have a great deal of exibility in terms of their chemical composition 61,[64][65][66] and are now regarded as a basis for promising bioactive theranostic materials. 67,68 From the ndings of the current study, a paper-like material couldn't be classied as a layered rare earth hydroxide as the positions of the maxima in its diffraction pattern (see Fig.…”

Intercalation of Porphyrin‐Based SURMOF in Layered Eu(III) Hydroxide: An Approach Toward Symbimetic Hybrid Materials

“…[38] There are two main advantages of using LEuH as a planar supporting host for the active SURMOFs: i) LEuH can show certain catalytic activity in various reactions due to the well-known coordination properties of europium, [39][40][41][42] and ii) the luminescent properties of europium are very sensitive to the changes in its coordination sphere. [36,[42][43][44][45] That is, europium can act both as a catalytic center and as a signaling component which indicates the processes influencing the local environment within the catalyst. The SURMOF structures based on the metal complexes of porphyrins also enable two functions, a selective sorption and a catalytic activity, both due the ability of the metallated porphyrins to coordinate some organic anions.…”

“…Herein we report a study of a synergetic hybrid material assembled by intercalation of the components of porphyrinbased SURMOF into europium(III) hydroxychloride (LEuH) as a dispersed solid matrix. This compound is a layered material exhibiting anion-exchange properties, [31][32][33][34][35] which can be intercalated by various organic [36] or inorganic [37] anions and exfoliated to quasi-two-dimensional material. [38] There are two main advantages of using LEuH as a planar supporting host for the active SURMOFs: i) LEuH can show certain catalytic activity in various reactions due to the well-known coordination properties of europium, [39][40][41][42] and ii) the luminescent properties of europium are very sensitive to the changes in its coordination sphere.…”
