Films of regioregular chiral poly[(S)-3-(3,7-dimethyloctyl)thiophene] (see Figure) prepared via spin-coating and characterized by polarized UV-vis spectroscopy show that order along the film normal is present (which is proportional to the spinning rate). Phase-sensitive second-harmonic generation experiments demonstrate this order to be polar.
