Chiral sensing for induced circularly polarized luminescence using an Eu(III)-containing polymer and D- or L-proline

An Eu(III)-containing polymer can exhibit intense induced circularly polarized luminescence (CPL) in the presence of proline. In addition, the optical anisotropy factor (g(lum)) of the polymer for D-5(0) -> F-7(1)/F-7(2) transition was much higher than that of a single model molecule, which reveals the amplification effect of CPL arising from the conjugated polymer structure.
