Four isostructural lanthanide(III) complexes, [Ln 2 (HL) 2 (H 2 O) 4 ] n ·2nH 2 O (H 4 L = 3,3′,6,6′-tetracarboxyl-2,2′-bipyridine) (Sm ( 1 ), Eu ( 2 ), Gd ( 3 ), Tb ( 4 )), have been synthesized under the hydrothermal condition and characterized by single-crystal X-ray diffractions, powder X-ray diffractions (PXRD), thermal analyses (TGA) and elemental analyses (EA). These four complexes all exhibit 1D chain-like structures containing di-nuclear lanthanide(III) units, which are further linked by hydrogen bonding into 3D supramolecules. To further investigate the properties of the above complexes, the photoluminescent properties of 2 and 4 are also discussed.

The synthesis and the molecular and photophysical characterization, together with solid state and solution structure analysis, of a series of europium complexes based on β-diketonate ligands are reported. The Eu(III) complex emission, specifically its photoluminescence quantum yield (PL-QY), can be tuned by changing ligands which finely modifies the environment of the metal ion. Steady-state and time-resolved emission spectroscopy and overall PL-QY measurements are reported and related to geomet...

A new amide type bridging ligand, 1,5-bis{[(2'-(2-picolylaminoformyl))phenoxy]methyl}naphthalene (L), and its complexes with lanthanide ions (Ln Sm, Eu, Gd, Tb, and Dy) have been designed and assembled. The crystal structures of {[EuL(NO3)(3)(CH3OH)](H2O)}(n) and [TbL(NO3)(3)(CH3OH)](n) display one-dimensional (1-D) zig-zag coordination polymeric chains. At the same time, the solid state luminescent properties of the Sm, Eu, Tb, and Dy complexes were investigated at room temperature. The complex...

Abstract The role of homodinuclear and heterodinuclear lanthanide complexes as building blocks for polymeric materials is a significant field of study in recent years. Accessing the desired luminescent properties of lanthanides in the most efficient and practical way is an important part of designing such complex structures. This review describes the background of the photophysical properties of a select number of lanthanide ions. The synthesis and photophysical properties of dinuclear lanthanid...

Abstract We review here the synthetic strategies employed in a concerted effort to obtain new single molecule magnets based on lanthanide ions in the framework of the research program on Molecular Magnetism funded by the Deutsche Forschungsgemeinschaft. The reported systems are grouped in 4f–2p, 4f–3d, and pure 4f materials. While the use of compartmentalized ligands, assisted self assembly, and site-targeted reactions have provided interesting examples of high nuclearity clusters, mostly charac...

A new complex of 4-thiophen-3-yl-pyridine-2,6-bis(oxazoline) with Eu(III) triflate has been isolated. This complex and its Tb(III) analogue are luminescent in the solid state. The complexes dissolve with partial retention of the solid-state structure in acetonitrile to yield highly luminescent solutions with quantum yields of 76.2 and 58.6% for red and green emission, respectively.

The assembly of the metal clusters to multidimensional metal–organic frameworks remains one of the most attractive research frontiers due to its attractive architectures and excellent properties. Compared with transition metals, the cluster chemistry of lanthanide ions is less developed. The chapter mainly highlights recent research progress on the synthetic strategy, structures, and properties of metal–organic frameworks based on lanthanide clusters. Varying from di- to octatetraconta-nuclei, l...
