Tuning Polymorphism, Molecular Orientation and Crystallinity in P(NDI2OD-T2) Thin Films Informed by Hansen Solubility Analysis

Key Points

• This research aims to explore how solvent choice affects the polymorphism and crystalline structure of P(NDI2OD-T2) thin films.
• Utilized Hansen solubility analysis to select appropriate solvents
• Applied thermal annealing to produce crystalline polymorphs
• Characterized thin films for molecular orientation and crystallinity
• Demonstrated that solvent selection significantly influences crystalline polymorph formation
• Observed variations in molecular orientation related to solvent choice
• Found that thermal annealing resulted in distinct crystallinity levels across samples
