Experimental values for semiconducting properties of the DPP pigments.
| Material | Band gap (eV) CV estimate | Band gap (eV) optical | HOMO (eV) | LUMO (eV) | Exp. mobility (cm2/V s) |
|---|---|---|---|---|---|
| DPP | 2.1 | 2.1 | −5.4 | −3.3 | μe = 0.01 μh = 0.01 |
| p-Cl-DPP | 2.8 | 2.1 | −6.0 | −3.2 | μe = 0.03 μh = 0.01 |
| p-Br-DPP | 2.7 | 2.1 | −6.1 | −3.4 | μe = 0.06 μh = 0.02 |
