Self-Assembly of 3d-4f ZnII-LnIII (Ln = Ho and Er) Bis(salamo)-Based Complexes: Controlled Syntheses, Structures and Fluorescence Properties

Syntheses, structures and photophysical properties of heterotrinuclear Zn2Ln clusters (Ln = Nd, Eu, Tb, Er, Yb).

Heterotrinuclear Zn(2)Ln (Ln = Nd 2, Eu 3, Tb 4, Er 5, Yb 6) clusters [(Znq(2))(2)](mu-CH(3)COO){Ln(hfac)(2)} (q = 8-hydroxylquinolinate, hfac = hexafluoroacetylacetonate) have been synthesized. The Zn(2)Ln framework is ligated by two q ligands featuring mu-phenoxo and two q ligands featuring mu(3)-phenoxo coordination modes, and one mu-CH(3)COO(-) anions. Since the short intramolecular separat...

Square structures and photophysical properties of Zn(2)Ln(2) complexes (Ln = Nd, Eu, Sm, Er, Yb).

Heterotetranuclear Zn(2)Ln(2) (Ln = Nd , Eu , Sm , Er , Yb ) complexes {Zn(2)(Mq)(2)(tpyO)(2)}{(Ln(hfac)(3))(2)} (HMq = 2-methyl-8-hydroxylquinoline, tpyOH = [2,2':6'2'']terpyridin-4'-ol, hfac = hexafluoroacetylacetonate) display novel square structures ligated by bifunctional ligands tpyO (mono- and tridentate) and Mq (chelating and bridging mu-phenoxo). These compounds exhibit sensitized lant...

Syntheses, Crystal Structures, and Optical and Magnetic Properties of Some CsLnCoQ3 Compounds (Ln = Tm and Yb, Q = S; Ln = Ho and Yb, Q = Se)

The four new compounds CsTmCoS3, CsYbCoS3, CsHoCoSe3, and CsYbCoSe3 have been synthesized at 1123 K. These black-colored isostructural compounds crystallize in the KZrCuS3 structure type with four formula units in space group Cmcm of the orthorhombic system. The structure of these compounds is composed of 2 [LnCoQ3 ] layers separated by Cs atoms. Because there are no Q Q bonds, the formal oxida...

Chromophore-labelled, luminescent platinum complexes: syntheses, structures, and spectroscopic properties.

Ligands based upon 4-carboxamide-2-phenylquinoline derivatives have been synthesised with solubilising octyl hydrocarbon chains and tethered aromatic chromophores to give naphthyl (), anthracenyl () and pyrenyl () ligand variants, together with a non-chromophoric analogue () for comparison. (1)H NMR spectroscopic studies of the ligands showed that two non-interchangeable isomers exist for and w...
