Notes:
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.
