Optical properties were compared between the isomeric poly[(2,5-dialkoxy-1,4-phenylenevinylene)-alt-(1,3-phenylenevinylene)] derivatives with different content of cis-/trans-vinylene bond linkages. The polymer of about 33% vinylene in the trans-configuration exhibited an absorption λ max ≈394 nm, which was blue-shifted by as much as 20 nm from its trans-vinylene-enriched isomer (λ max...
The electroluminescence and photoluminescence of poly(m-phenylenevinylene)-alt-(p-phenylenevinylene) green light emitting copolymers have been studied. The effect of alkoxy substitutions (-OC 4 H 9 and -OC 6 H 13 ) in single and double layer device configurations was also investigated. In double layer devices, poly(p-phenylene vinylene), PPV (60 nm) was used as...
