2019, Materials Science in Semiconductor ProcessingCitation Excerpt :Still analyzing the π-A isotherms, the area per molecule of the more condensed state for the P3HT film is approximately 7.2 Å2. The area per monomer obtained experimentally is lower than the thiophene ring calculated area, that is 14.7 Å2 when the ring is oriented perpendicularly to the water surface [35]. This lower attained area is already published for other organic polymers [36,37], and suggests the self-organization of these materials that form aggregates and may be folding towards the air phase, thus a true monolayer is not achieved.

2017, Colloids and Surfaces A: Physicochemical and Engineering AspectsCitation Excerpt :For the thiophene rings, the area calculated by the Corey–Pauling–Koltum (CPK) model should be 14.7 Å2. Thus this is the expected area per repeat unit if the polymer backbone is disposed on the water surface with all the rings perpendicular to the air water-interface [32,33]. However, when a polythiophene with short alkoxy substituents has the rings lying down parallel to the water surface, the area per monomeric unit is supposed to be around 28 Å2 [34].
