Molecular orientation in vacuum-deposited poly(thiophene) film studied by second-harmonic generation
The molecular orientation of the vacuum-deposited polythiophene (PT) film has been studied by second-harmonic generation (SHG). The polythiophene main chain is preferably oriented to be perpendicular to the substrate normal. The chain tilt angle from the surface normal decreased with increasing subs...
