Table 2. Morphology Parameters of 9a–c Thin Films Determined by XRD Patterns.
| compound | d (Å) | L (Å)a | θ (deg)b | l (nm)c |
|---|---|---|---|---|
| 9a | 17.0 | 16.9 | ∼0 | 20.5 |
| 9b | 31.0 | 36.6 | 32 | 24.7 |
| 9c | 34.0 | 41.4 | 35 | 28.9 |
Defined as the distance between the terminal methyl groups in the alkyl chains in a DFT (B3LYP/6-31G(d))-optimized molecular structure.
Based on (d001) and the molecular length.
From the full width at half-maximum of (001) diffraction using the Debye–Scherrer formula.
