para-Derivatized Pybox ligands as sensitizers in highly luminescent Ln(III) complexes
New complexes of pyridine-bis(oxazoline) derivatized with -H, -OMe, and -Br at the para position of the pyridine ring with Eu(III) and Tb(III) have been isolated. These are highly luminescent in the solid state, regardless ...
Aromatic N-Donor Ligands as Chelators and Sensitizers of Lanthanide Ion Emission
Recent advances in the coordination of lanthanide ions and sensitization of their luminescence with aromatic N-donor ligands are presented.
2-Chloro-5-nitrobenzoato complexes of Eu(III) and Tb(III) - A 1D coordination polymer and enhanced solution luminescence
A luminescent 2-chloro-5-nitrobenzoic acid derivative of Eu(III) with a columnar structure has been isolated and characterized. This compound shows red emission in the solid state. Solutions of the ligand and Eu(III) in ...
Intermolecular forces and functional group effects in the packing structure of thiophene derivatives
Thiophene was derivatized at the β-carbon with isophthalic, dipicolinic, and four nitrobenzoic acids to yield 4-thiophen-3-yl-pyridine-2,6-dicarboxylic acid diethyl ester, I; 5-thiophen-3-yl-isophthalic acid diethyl ester, ...
Unusual nitro-coordination of Eu(III) and Tb(III) with pyridinyl ligands
A new ligand family based on picoline, bipyridine and terpyridine containing a nitro moiety has been synthesized and its coordination and sensitization ability for lanthanide ions has been studied. Three new complexes were ...
Thiophene-derivatized pybox and its highly luminescent lanthanide ion complexes
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 ...
Eu(III) and Tb(III) Luminescence Sensitized by Thiophenyl-Derivatized Nitrobenzoato Antennas
Thiophenyl-derivatized nitrobenzoic acid ligands have been evaluated as possible sensitizers of Eu(III) and Tb(III) luminescence. The resulting solution and solid-state species were isolated and characterized by luminescence ...
Nitro-functionalization and quantum yield of emission of Eu(III) and Tb(III) benzoic acid complexes
In our pursuit of luminescent lanthanide ion-based coordination polymers, we have isolated several complexes with nitrobenzoic acid ligands and characterized these by X-ray crystallography and luminescence spectroscopy. ...
