Abstract

Perfectly π-conjugated cobaltacyclopentadiene oligomer and polymer complexes were synthesized by polycondensation of a dihalogenated cobaltacyclopentadiene complex, [[upper bond 1 start]Co{C(C6H4I-4)[double bond, length half m-dash]CBunCBun[double bond, length half m-dash]C[upper bond 1 end](C6H4I-4)}(cp)(PPh3)] (cp = η5-C5H5), with [Ni(cod)2] (cod = cycloocta-1,5-diene). Their internuclear electronic interaction energy in the mixed-valence state, uOR, was estimated to be ca. –2 kJ mol–1 by electrochemical analysis.
