Brittain, Harry G. published the artcile< Optical activity in mixed-ligand terbium(III) complexes containing pyridine-2,6-dicarboxylic acid and chiral hydroxycarboxylic acids>, HPLC of Formula: 112-63-0, the main research area is optical activity terbium chiral hydroxycarboxylic.
The optical activity associated with the f-f emission bands of Tb(III) complexes which contain chiral hydroxycarboxylic acids was studied by means of circularly polarized luminescence (CPL) spectroscopy. Complexes having the general formulas Tb(DPA)(L) and Tb(DPA)2(L) were studied (where DPA signifies pyridine-2,6-dicarboxylate), with the chiral L ligand being L-lactic acid, L-α-hydroxyisocaproic acid, L-argininic acid, L-mandelic acid, L-phenyllactic acid, L-malic acid, L-hydroxyglutaric acid, and D-isocitric acid. The CPL spectra were sensitive to the mode of bonding existing between the metal and the chiral ligand and therefore enabled predictions to be made regarding how the hydroxycarboxylic acid ligands attach to the Tb(III) ion. In addition, the degree of optical activity varied systematically with the concentration of chiral ligand, and this dependence was used to calculate formation constants for the addition of a hydroxycarboxylic acid ligand to the Tb/DPA complexes. Finally, the line shapes and magnitudes of the CPL spectra provide information regarding the type of chirality experienced by the Tb(III) ion.
