The substitution of every second phenylene subunit in the well‐known poly( p ‐phenylenevinylene) (PPV) by o , o ′‐bridged biphenyl moieties leads to the novel poly(1,4‐phenylenevinylene‐2,2′‐biphenylylenevinylene) (PPVBV, 5) which can be prepared by palladium‐catalyzed aryl‐olefin coupling (Heck reaction). PPVBV possesses a high solubility in common organic solvents and good filmforming capabilities. It exhibits a thermochemical and photochemical reactivity comparable to that of the monomeric model compound 2,2′‐distyrylbiphenyl ( 3 ), which undergoes a [2+2]cycloaddition upon heating or irradiation.
