| τ0 | Φdegr (%) | |
|---|---|---|
| [Fe(bpy)2(CN)2] | (650 ± 25) ps(MC) | 8.8 × 10–5 |
| [Fe(bpy)2(BCF)2] | (67 ± 2) ps(MC) | 1.5 × 10–5 |
| [Fe(bpy)(CN)4]2– | 18 ps (MLCT)22 | 4.9 × 10–3 |
| [Fe(bpy)(BCF)4]2– | (28 ± 3) ps(MC) | 4.9 × 10–5 |
The dominant character of their lowest excited state is indicated in parentheses.
