| polymer | Mn (PDI) (kDa) | ad (°C) | λmaxsoln (nm) | aλmaxfilm (nm) | bEHOMO (eV) | cELUMO (eV) | dEgopt (eV) |
|---|---|---|---|---|---|---|---|
| PfBTAZT-BDT | 94(2.4) | 420 | 348, 571 | 351, 577 | –5.27 | –3.45 | 1.82 |
| PfBTAZT-fBDT | 85(2.5) | 431 | 350, 580 | 353, 579 | –5.37 | –3.58 | 1.79 |
Polymer thin films on the quartz plate cast from chloroform solution.
EHOMO = −(4.80 + Eoxonset – 0.49).
ELUMO = EHOMO – Egopt.
Calculated from the absorption edge of the polymer films: Egopt = 1240/λedg.
