title = "Optical sensing of chiral polymer thin films",
abstract = "The chiroptical properties of polyfluorene–phenylene (PFPh) thin films were studied using circular dichroism (CD), surface-enhanced Raman scattering (SERS), attenuated total reflection (ATR), and spectroscopic ellipsometry. The pristine PFPh films exhibited significant CD at room temperature, and the chirality increased by thermal annealing at 120 ?. SERS and ATR spectra indicated that the chirality enhancement was due to the self-organization and/or rearrangement of the polymer backbones by thermal annealing. Optical sensing of the chiral polymers was demonstrated using SERS spectra of the chiral polymer films on gold. Optical sensing properties of the chiral PFPh films were compared with those of the achiral polyfluorene films.",
