Polar Order in Spin-Coated Films of a Regioregular Chiral Poly[(S)-3-(3,7-dimethyloctyl)thiophene]

Polar Order in Spin-Coated Films of a Regioregular Chiral Poly[(S)-3-(3,7-dimethyloctyl)thiophene]

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 ex...

Zusammenfassung: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.
