25. The emissive state of 2 is still under investigation. The oxidation of 2 is not observed within the 1.8 V solvent window, but the complex should be to the right of complex 1 in Figure 3. The emission energy is calculated to be 148 V.
26. 00 for 1 and 2 was determined to be 2.25 and 2.48 V, respectively.
