Bis(ferrocenyl)polymethine cations. A prototype molecular wire with redox-active end groups
- Georgia Inst. of Technology, Atlanta, GA (United States)
We have previously provided evidence for solitonic behavior in polymethines using {alpha}{omega}-diphenylpolyenyl anions (DPN{sup -}, X = Ph) and {alpha}{omega}-dipyridocyanines (DPyN{sup +}, X = py-CH{sub 3}). We now extend this approach to molecular wires involving polymethines with redox-active end groups. In this communication, we report the synthesis and characterization of {alpha}{omega}-bis(ferrocenyl)polymethine cations (acronym DFcN{sup +}, X = C{sub 5}H{sub 5}) as part of our systematic investigation of solitonic behavior in molecules (`solitons in a box`). Ferrocene end groups provide stable, low-potential redox-active termini and allow strong coupling of the redox centers with the polyene chain. The first two members of this series (DFcL{sup +}, DFc3{sup +}) were generated according to literature methods. The remaining members were synthesized through conventional Wittig methodology. 20 refs., 3 figs., 2 tabs.
