Chiral Emissive Lanthanide Complexes from Enantiopure [6]Helicene?bis(pyrazolyl)?pyridine Ligands

Near infrared (NIR) lanthanide emissive Langmuir-Blodgett monolayers formed using Nd(III) directed self-assembly synthesis of chiral amphiphilic ligands.

The incorporation of chiral amphiphilic lanthanide-directed self-assembled Nd(III) complexes (Nd.13 and Nd.23) into stable Langmuir monolayers, and the subsequent Langmuir-Blodgett film formation of these, is described. The photophysical properties of the enantiomeric pair of ligands 1 and 2 in the presence of Nd(CF3SO3)3 were also investigated in CH3CN solutions using UV-vis, fluorescence, and...

Highly emissive platinum(II) complexes bearing carbene and cyclometalated ligands.

A series of heteroleptic platinum(II) complexes (1a-3a and 1b-3b) bearing a dicarbene ligand and a cyclometalated bidentate ligand have been prepared. Two of the complexes (1a and 3a) were characterized by X-ray diffraction analyses, confirming the square-planar structures. Detailed spectroscopic properties of the complexes have been studied, and two complexes, 3a and 3b bearing a carbene chela...

Induced circularly polarized luminescence arising from anion or protein binding to racemic emissive lanthanide complexes.

A circularly polarized luminescence (CPL) spectrometer has been built and used to study the binding interaction of lactate and four different proteins with racemic EuIII and TbIII complexes in aqueous solution. Lactate binding gives rise to strong induced CPL spectra, and the observed emission dissymmetry factors vary linearly with enantiomeric composition. Particularly strong induced TbIII CPL...

Bidentate Schiff Base derived from quinolone Ligands Oxovanadium (IV) Complexes

Lanthanide complexes assembled from two flexible amide-type tripodal ligands: terminal groups effect on photoluminescence behavior.

To explore the effect of terminal groups of tripodal ligands on the photoluminescence behaviors of the complexes, lanthanide (Eu(III), Tb(III)) nitrate complexes with two flexible amide-type tripodal ligands, 2,2',2''-nitrilotris-(N-phenylmethyl)-acetamide (L(I)) and 2,2',2''-nitrilotris-(N-naphthalenemethyl)-acetamide (L(II)) were synthesized and characterized. The general formulas of the comp...
