    Abstract:
    Ultraviolet (UV), Circular Dichroism (CD), Fluorescence, and Circularly Polarized Luminescence (CPL) spectra were recorded for mixed chloroform/methanol and chloroform/butanol solutions of regioregular poly[3-((S)-2-methylbutyl)-thiophene]. An evaluation of the chiral and nonchiral components in solution is proposed on the basis of the UV and CD spectra. The fluorescence and CPL spectra are observed in a wavelength range where some UV and CD activity still appears. For this reason, the observed CPL features are strongly influenced by CD. A general procedure for evaluating true CPL spectra is proposed, when absorption and emission coexist.
