“…The solution structure was optimized on the basis of the experimental proton pseudocontact shifts (PCS) through the computer program PERSEUS. 16,18 PERSEUS modifies the dihedrals describing the rotation around N -C and C -C bonds of the side arms, starting from a tentative structure of Yb-3 and varying the position of the metal with respect to the ligand. For each conformation, the paramagnetic shifts of the ligand protons are calculated using Eq.…”

“…Thus PCSs can be used as structural restraints for calculation of the solution structure. 16,18 The Yb(III) ion is also active in optical spectroscopy owing to the intra-configurational f -f electronic transitions of the metal ion. The relative absorptions fall in the near-IR region, far from the typical bands of most ligands.…”

“…However, lanthanides such as Yb III and Nd III are being explored for their use as probes because they emit in the near IR (NIR), which is beneficial for biological studies since NIR wavelengths are efficiently absorbed by cells. [28][29][30][31][32][33] Time-resolved luminescence lifetimes, luminescence intensity, [32] ratiometrics of emission bands, [11,13] excitation spectra, and polarization [34,35] of Ln III photoluminescence are characteristics that have been used to discriminate between anions of biological interest upon interaction with Ln III complexes. Dinuclear Ln III ion complexes are of interest as luminescent sensors partly because their anion binding properties are different than those of their mononuclear analogs.…”

“…An interpretation of the spectra of Yb1 and Yb2 was achieved with the aid of the program PERSEUS. 21,22 The MM structures for Yb1 and Yb2 were assumed for the input ligand geometry. These provided reasonably good fits of the δ pc , leaving only the five independent components of the tensor χ as variables, as shown in Table 1 and Table 2.…”
