摘要:
Isomeric diruthenium complexes with bis(ethynyl)pyridine as bridge core [2,6-bis(ethynyl)pyridine ( 1 ), 3,5-bis(ethynyl)pyridine ( 2 ), 2,5-bis(ethynyl)pyridine ( 3 )] were successfully prepared and characterized by 1 H NMR, 13 C NMR and elemental analysis. The electrochemical properties of complexes 1-3 were inves-tigated by cyclic voltammetry (CV) and square-wave voltammetry (SWV), and different potential differ-ence values were revealed and affected by N atom position and distance between redox metal centers. Electron absorption spectra showed that the absorption of the linear molecule 3 d...
