Synthesis and Luminescent Properties of Lanthanide Complexes with Benzothiazolylphenolate and -Naphtholate Ligands

Synthesis and photophysical properties of rare earth (La, Nd, Gd, Y, Ho) complexes with silanediamido ligands bearing a chelating phenylbenzothiazole chromophore

“…Substituted 2-phenyl-benzothiazoles have been widely explored in the chemistry of transition metals and as OLEDs themselves, followed by the studies of lanthanide complexes. [29][30][31][32][33][34] This chromophore group provides a necessary absorption to the complex, and efficiently transfers the excitation to the lanthanide, owing to the bidentate coordination by heteroatoms. The triplet level energy of the protonated Pbt-derivatives was recently determined 31 to be around 20 Â 10 3 cm À1 ; upon deprotonation, the triplet level energy is noticeably decreased and becomes closer to the excited levels of NIR-emitting lanthanides.…”

Synthesis and Structure of a Samarium Complex with Perylene

“…Only one type of perylene complexes of lanthanides is known, LnI(Per)(DME) 2 (Ln = Dy, Nd), 34 where perylene is a dianion. Lanthanide complexes and metal complexes with other metals, except for alkali metals, containing the perylene radical anion, were not obtained.…”

“…Recently shown that DyI 2 and NdI 2 reduce perylene to the dianion with the formation of complexes LnI(Per)(DME) 2 . 34 SmI 2 does not reduce perylene under the same conditions, so a different approach was used to obtain the samarium perylene complex, which will be discussed in this article.…”

Mono- and Mixed Metal Complexes of Eu3+, Gd3+, and Tb3+ with a Diketone, Bearing Pyrazole Moiety and CHF2-Group: Structure, Color Tuning, and Kinetics of Energy Transfer between Lanthanide Ions

“…However, 1,3-diketones with pyrazole moieties and CHF 2 -groups have never been studied as ligands before. Here we want to report on our first results on synthesis and luminescent properties of Tb 3+ , Eu 3+ and Gd 3+ complexes with 1-(1,5-dimethyl-1H-pyrazol-4-yl)-4,4-difluorobutane-1,3-dione (3).…”

“…The unique luminescent properties of lanthanide ions are actively studied due to the possibility of their use in emitting materials [ 1 , 2 , 3 ], biovisualization [ 4 , 5 , 6 , 7 ], banknote protection [ 8 ] and in creating sensing materials [ 9 , 10 , 11 ].…”
