Ladder-like polyacetylene with excellent optoelectronic properties and regular architecture

摘要

Novel double-stranded polyacetylene with a perylene bisimide bridge has been efficiently synthesized by metathesis cyclopolymerization of bis(1,6-heptadiyne) derivatives, and exhibited good solubility, highly thermal and oxidative stability, low LUMO energy levels, narrow band-gaps, and regular ladder-like architecture.
