Effect of the solubility parameter of the solvent on the film-forming behavior and polymer aggregation of the conjugated polymer |
| 초록 |
Solvent-additive engineering is an effective strategy for producing organic semiconductors with high crystallinity. We investigate how the physicochemical properties of a additive solvent influence to the aggregation of a conjugated polymer and film-forming behavior. We chose alcohol-based polar solvents as a additive solvent that induce polymer aggregation. We demonstrated that the polarity of the solvent additive strongly affects its miscibility with the main solvent and the ability of the resultant mixed solvent to dissolve the poly(3-hexylthiophene); this solvation ability was related to the intermolecular force of the dipole−dipole interaction. Whereas, we found that during polymer film formation, the evaporation sequence and solvent composition play more influential roles than dipole−dipole interactions in determining the crystallinity of the resultant polymer film. We fabricated a highly crystalline P3HT film based organic field-effect transistor with enhanced charge mobility. |
