Large Electronic Coupling in a Homoconjugated Donor–Acceptor System Involving Carbon-bridged Oligo(p-phenylenevinylene) and Triazine

We have synthesized a new homoconjugated donor–acceptor (D–A) system featuring a rigid planar carbon-bridged oligo(p-phenylenevinylene) that shows efficient intramolecular charge separation (CS, 98%). The charge recombination rate is 100-times slower than that of CS, and located in the Marcus invert...

Zusammenfassung:We have synthesized a new homoconjugated donor–acceptor (D–A) system featuring a rigid planar carbon-bridged oligo(p-phenylenevinylene) that shows efficient intramolecular charge separation (CS, 98%). The charge recombination rate is 100-times slower than that of CS, and located in the Marcus inverted region. The electronic coupling was estimated to be 1.0 × 103 cm−1, which is one of the largest values among reported D–A interactions.
