Phosphorescent composition comprises an alkaline earth metal silicate doped with europium fluoride and another lanthanide fluoride. Independent claims are also included for: (1) producing a composition as above by grinding a mixture of alkaline earth metal ...
A new class of benzimidazole-substituted 8-hydroxyquinoline ligands has been prepared that contain a monoanionic tridentate N,N,O-coordinating unit. These ligands form charge-neutral lanthanide complexes of the type [Ln(LR) 3] · nH2O or [Ln2(L2)3] · nH2O ( ...
The diastereoselective synthesis of chiral coordination compounds with d metals proved the effectiveness of the pinene-bipyridine approach in predetermining the chirality at the metal centre. The strong Lewis acidic character of lanthanide cations required ...
Treatment of Ln(NO3)3.nH2O with 1 or 2 equiv 2,2-bipyrimidine (BPM) in dry THF readily afforded the monometallic complexes [Ln(NO3)3(bpm)2] (Ln=Eu, Gd, Dy, Tm) or [Ln(NO3)3(bpm)2]THF (Ln=Eu, Tb, Er, Yb) after recrystallization from MeOH or THF, respectivel ...
The ionic liquid crystal [C12-mim]Cl has been doped with 5 mol% europium nitrate and the photophysical properties of both the ionic liquid and the trivalent europium ion have been monitored with respect to temperature in the range of 248 to +120 uC. The re ...
The segmental bidentate–tridentate–bidentate ligand L2 reacts with MII (M = Cr, Zn) and LnIII (Ln = La, Eu, Gd, Tb, Lu) to give the heterotrimetallic triple-stranded helicates [MLnM(L2)3]7+. For M = ZnII, the isolated complexes ZnLnZn(L2)37 (Ln = ...
Mononuclear trivalent lanthanide complexes with formula [Ln(L)(NO3)3] [in which L=4,4-difluoro-8-(2:2;6:2-terpyridin-4-yl)-1,3,5,7-tetramethyl-2,6-diethyl-4-bora-3a,4a-diaza-s-indacene (Boditerpy)] are reported for Ln=Yb, Nd, Er, La and Gd. According to th ...
