Poly(pentafulvalene)s: One-Dimensional Conjugated Hydrocarbons toward Stable and Narrow-Bandgap Polyenes

Polyacetylene is the archetypal narrow-bandgap conjugated polymer, yet its high-lying HOMO renders it air-sensitive, and aromatic alternatives sacrifice the small bandgap inherent to a polyene backbone. Here we show that embedding the polyene in a dibenzopentafulvalene (DBF) fram...
