Abstract (en)

[origin: WO9914255A1] Poly(9,10-anthrylene vinylene)s, including substituted derivatives thereof, preferably having in excess of seven anthrylene units in each polymer chain are synthesised by polymerising a dibenzobarrelenes using a metal catalysed ring-opening olefin metathesis polymerization (ROMP) reaction under oxygen-free conditions. The anthrylene units in the resulting poly(9,10-dihydro-9,10-anthrylene vinylene) may be totally or partially 9,10-dehydrogenated using heat or an oxidising agent such as DDQ.
