Lanthanide-containing luminescent molecular edifices

Effect of varying lanthanide local coordination sphere on luminescence properties illustrated by selected inorganic and organic rare earth complexes synthesized in sol–gel host glasses

“…Lanthanides have scientific and technological applications in many areas, including materials sciences, biochemistry, condensed matter physics, solidstate chemistry and solution chemistry [7,[12][13][14][15][16][17][18][19][20][21][22]. Among the lanthanide ions that emit in the visible range of the spectrum, Eu(III), Tb (III) and Tm (III) are the most attractive due to the emission of three primary colors red, green and blue, respectively [23][24][25].…”

Synthesis, Characterization and Antimicrobial Screening of 1,3-Dione with their Metal Complexes

“…Wavenumber of electronic absorption spectra as shown in Table- H NMR spectral data of the 1-(5-bromo-2-hydroxyphenyl)-3-(thiophen-2-yl) propane-1,3-dione (L) shows singlet at δ 15.59 ppm due to enolic proton, a singlet at δ 11.93 ppm due to phenolic proton adjacent to the carbonyl group which confirms the formation of β-diketone. In the 13 C NMR of ligand 4, peak appeared at δ 193.33 ppm corresponds to carbonyl carbon (C=O) and enolic carbon (C-O) at δ 173.62 ppm. The signal at δ 91.67 ppm appeared shows methine linkage.…”

“…Europium(III)-diketonates have excellent luminescent property [13]. It is also used as chelating agent [14] and extractants for lanthanide ions [15].…”

Synthesis and evaluation of the europiumIII and zincII complexes as luminescent bioprobes in high content cell-imaging analysis

“…The development of novel luminescent probes for intracellular analysis, that are efficient and kinetically stable, is one of the vital goals. Rare earth metal complexes are now versatile targets in many areas of research such as photochemistry, biomedicine and nanotechnology [5][6][7][8][9][10][11][12]. Special attention has been given to the luminescence properties of lanthanide ions emitting at a millisecond lifetime-scale and in the visible region for europium(III) and terbium(III) complexes [13][14][15][16].…”
