The complexation behavior of two novel, chiral pinene–bipyridine-type ligands ((–)-HL1 and (–)-HL2) containing a carboxylic arm towards lanthanide Ln(III) (Ln = La, Eu, Lu) ions was investigated through spectroscopic methods. The association constants of the mononuclear complexes determined from the UV-Vis titrations indicated that the ligand (–)-HL1 possessing a shorter carboxylic arm formed more stable complexes compared with (–)-HL2, whose carboxylic arm had one more methylene unit. This is due to the formation of more stable seven-member metal chelate rings in the first case as compared with the eight-member metal chelate rings in the second. IR and fluorescence spectroscopy provided additional information about the structure of these complexes.

The iodine complexes of naphthalene, biphenyl, hexamethylbenzene, aniline, and o-toluidine in carbon tetrachloride were studied by using the constant activity method. The association constants and the heats of formation of the complexes were determined and the results are compared with those obtained by using conventional spectral methods. The blue-shifted iodine band maxima were determined directly.
