Abstract
The complexes [Eu(bpcd)(tta)], [Eu(bpcd)(Coum)], and [Tb(bpcd)(Coum)] [tta = 2-thenoyltrifluoroacetyl-acetonate, Coum = 3-acetyl-4-hydroxy-coumarin, and bpcd = N,N'-bis(2-pyridylmethyl)-trans-1,2-diaminocyclohexane-N,N'-diacetate] have been synthesized and characterized from photophysical and thermodynamic points of view. The optical and chiroptical properties of these complexes, such as the total luminescence, decay curves of the Ln(III) luminescence, electronic circular dichroism, and circularly polarized luminescence, have been investigated. Interestingly, the number of coordinated solvent (methanol) molecules is sensitive to the nature of the metal ion. This number, estimated by spectroscopy, is >1 for Eu(III)-based complexes and <1 for Tb(III)-based complexes. A possible explanation for this behavior is provided via the study of the minimum energy structure obtained by density functional theory (DFT) calculations on the model complexes of the diamagnetic Y(III) and La(III) counterparts [Y(bpcd)(tta)], [Y(bpcd)(Coum)], and [La(bpcd)(Coum)]. By time-dependent DFT calculations, estimation of donor-acceptor (D-A) distances and of the energy position of the S1 and T1 ligand excited states involved in the antenna effect was possible. These data are useful for rationalizing the different sensitization efficiencies (ηsens) of the antennae toward Eu(III) and Tb(III). The tta ligand is an optimal antenna for sensitizing Eu(III) luminescence, while the Coum ligand sensitizes better Tb(III) luminescence {ϕovl = 55%; ηsens ≥ 55% for the [Tb(bpcd)(Coum)] complex}. Finally, for the [Eu(bpcd)(tta)] complex, a sizable value of glum (0.26) and a good quantum yield (26%) were measured.

Abstract
![]()
In this work, we investigated from a theoretical point
of view
the dynamics of the energy transfer process from the ligand to Eu(III)
ion for 12 isomeric species originating from six different complexes
differing by nature of the ligand and the total charge. The cationic
complexes present the general formula [Eu(L)(H2O)2]+ (where L = bpcd2– = N,N′-bis(2-pyridylmethyl)-trans-1,2-diaminocyclohexane N,N′-diacetate;
bQcd2– = N,N′-bis(2-quinolinmethyl)-trans-1,2-diaminocyclohexane N,N′-diacetate; and bisoQcd2– = N,N′-bis(2-isoquinolinmethyl)-trans-1,2-diaminocyclohexane N,N′-diacetate), while the neutral complexes present
the Eu(L)(H2O)2 formula (where L = PyC3A3– = N-picolyl-N,N′,N′-trans-1,2-cyclohexylenediaminetriacetate; QC3A3– = N-quinolyl-N,N′,N′-trans-1,2-cyclohexylenediaminetriacetate;
and isoQC3A3– = N-isoquinolyl-N,N′,N′-trans-1,2-cyclohexylenediaminetriacetate).
Time-dependent density functional theory (TD-DFT) calculations provided
the energy of the ligand excited donor states, distances between donor
and acceptor orbitals involved in the energy transfer mechanism (RL), spin-orbit coupling matrix elements, and
excited-state reorganization energies. The intramolecular energy transfer
(IET) rates for both singlet-triplet intersystem crossing and ligand-to-metal
(and vice versa) involving a multitude of ligand and Eu(III) levels
and the theoretical overall quantum yields (ϕovl)
were calculated (the latter for the first time without the introduction
of experimental parameters). This was achieved using a blend of DFT,
Judd–Ofelt theory, IET theory, and rate equation modeling.
Thanks to this study, for each isomeric species, the most efficient
IET process feeding the Eu(III) excited state, its related physical
mechanism (exchange interaction), and the reasons for a better or
worse overall energy transfer efficiency (ηsens)
in the different complexes were determined. The spectroscopically
measured ϕovl values are in good agreement with the
ones obtained theoretically in this work. Photophysical properties of 12 Eu(III)
complexes with pyridine,
quinoline, and isoquinoline ligands in aqueous solutions were elucidated
and predicted through a theoretical protocol using a blend of DFT,
Judd−Ofelt theory, intramolecular energy transfer theory, and
coupled rate equation modeling calculations. The theoretical procedure
is general and can be extended to any lanthanide-based complexes.

Abstract
Recently developed dynamic nuclear polarization (DNP) technology offers the potential of increasing the NMR sensitivity of even rare nuclei for biological imaging applications. Hyperpolarized 89 Y is an ideal candidate because of its narrow NMR linewidth, favorable spin quantum number (I=1/2 ), and long longitudinal relaxation times (T1 ). Strong NMR signals were detected in hyperpolarized 89 Y samples of a variety of yttrium complexes. A dataset of 89 Y NMR data composed of 23 complexes with polyaminocarboxylate ligands was obtained using hyperpolarized 89 Y measurements or 1 H,89 Y-HMQC spectroscopy. These data were used to derive an empirical equation that describes the correlation between the 89 Y chemical shift and the chemical structure of the complexes. This empirical correlation serves as a guide for the design of 89 Y sensors. Relativistic (DKH2) DFT calculations were found to predict the experimental 89 Y chemical shifts to a rather good accuracy.

Abstract
The eight-coordinate (enH2)[YIII(pdta)(H2O)](2)·10H2O (en=ethylenediamine and H4pdta=1,3-propylenediamine-N,N,N',N'-tetraacetic acid) was synthesized, meanwhile its molecular and crystal structures were determined by single-crystal X-ray diffraction technology. The interaction between [Y(III)(pdta)(H2O)]2(2-) and bovine serum albumin (BSA) was investigated by UV-vis and fluorescence spectra. The results indicate that [YIII(pdta)(H2O)]2(2-) quenched effectively the intrinsic fluorescence of BSA via a static quenching process with the binding constant (Ka) of the order of 10(4). Meanwhile, the binding and damaging sites to BSA molecules were also estimated by synchronous fluorescence. Results indicate that the hydrophobic environments around Trp and Tyr residues were all slightly changed. The thermodynamic parameters (ΔG=-25.20 kJ mol(-1), ΔH=-26.57 kJ mol(-1) and ΔS=-4.58 J mol(-1) K(-1)) showed that the reaction was spontaneous and exothermic. What is more, both ΔH and ΔS were negative values indicated that hydrogen bond and Van der Waals forces were the predominant intermolecular forces between [YIII(pdta)(H2O)]2(2-) and BSA.
