| Description: |
The two ligands 2,6-bis4-methylquinolin-2-ylpyridine L1 and diethyl 2,2prime;-pyridine-2,6-diylbisquinolone-4-carboxylate L2 were used to prepare the homoleptic [RuL22][PF6]2nbsp;RU1 and heteroleptic [RuL1L2][PF6]2nbsp;RU2 complexes. DFT calculations B3PW91,3-21G performed on both RU1 and RU2 revealed that redox at the ruthenium site for RU2 is less positive by ca. 110 mV. Consequently, the one-electron ligand-based reduction for RU2 is more cathodic by 80 mV. Electrochemistry experiments confirmed that the prediction is qualitatively correct and that the complexes can each hold up to five electrons reversibly. The ligands diethyl 2,2prime;-pyridine-2,6-diylbisquinolone-4-carboxylate L2 and 2,6-bis4-methylquinolin-2-ylpyridine L1 were used to prepare the homoleptic [RuL12][PF6]2nbsp;RU1 and heteroleptic [RuL1L2][PF6]2nbsp;RU2 complexes. Electrochemistry experiments showed that the complexes can hold up to five electrons reversibly. |
