The First Spiroconjugated TTF- and TCNQ-Type Molecules: A New Class of Electroactive Systems?
摘要:
Spiroconjugated TTF-type electron donors (13a-c) and TCNQ-type electron acceptors (10, 11) have been prepared from spiroquinone 9. Cyclic voltammetry reveals a relatively weak accepting ability for 10 and 11, and a strong electron-donor character for 13a-c. Whereas the spiroconjugation introduces a destabilization of the LUMO for compounds 9-11, the opposite is observed for compound 13. thus justifying the redox potential values.

characterized experimentally and theoretically, and the formation of charge transfer complexes with TCNQF2 and TCNQF4 has been reported. The chiroptical investigation of the neutral systems revealed significant differences in chiroptical activity depending on the nature of chiral centres and between diastereomers.
