Optical bandgaps and exciton lifetimes of BTT-DPP polymer films with differing number average molecular weights.
| Polymer name | Optical bandgap (eV) | Exciton lifetime (ps) |
|---|---|---|
| BTT-DPP 90 kg·mol−1 | 1.37 | 17.1 ± 1.5 |
| BTT-DPP 73 kg·mol−1 | 1.34 | 16.4 ± 1.0 |
| BTT-DPP 22 kg·mol−1 | 1.32 | 14.2 ± 1.2 |
