A series of oligoaniline-modified mono-and bis-nuclear iron(Ⅱ) complexes were synthesized successfully,and their spectroscopic and electrochemical properties were studied.The metal-to-ligand charge-transfer transition(¹MLCT) bands of the complexes with oligoaniline groups are considerably red-shifted(converge to 594 nm with increasing chain length) and their intensities become much more intense(approximately 5 times),compared with that of the reported complex [Fe(TPY)₂]²⁺.All the complexes show multiplicate redox processes based on the [Fe(TPY)₂]²⁺ core and oligoaniline unit.Their electrochemical behaviors can be modulated by changing the chain length and the substituent group in the oligoaniline unit.
