Description

The generation of circularly polarized light is important in many applications, including holographic displays, 3-D movies, and bioanalytical techniques. This presentation describes the synthesis and fluorescent analysis of chiral light emitting ionic liquids made from lanthanide-doped chiral amino acid ionic liquids. The ionic liquids were composed of tetrabutylammonium (TBA) cation countered with l-valine, d-valine, l-proline, or d-proline anions. These ionic liquids of varying amino acid composition were doped with europium trifluoromethanesulfonate (triflate) salt and analyzed by circularly polarized luminescence (CPL). The sign of CPL signal corresponded to the handedness of the amino acids in the ionic liquids. Europium triflate concentration dependent CPL in both [TBA][Val] and [TBA][Pro] ionic liquids was measured from 5 to 30 millimolal. CPL concentration dependent results indicate that ionic liquid properties play an important role.
