## Abstract Three alternating conjugated copolymers of cyanosubstituted poly(__p__‐phenylene vinylene) (CN–PPV) with phenylene ethynylene and thienylene vinylene moieties, **P1, P2,** and **P3,** were synthesized via cross‐coupling polycondensation with Pd(PPh~3~)~2~Cl~2~ as a catalyst. Their struc
## Abstract Two novel phenyl‐substituted poly(__p__‐phenylene vinylene) derivatives, poly{2‐[3′,4′‐(2″‐ethylhexyloxy)(3″,7″‐dimethyloctyloxy)benzene]‐1,4‐phenylenevinylene} (EDP‐PPV) and poly{2‐[3′,4′‐(2″‐ethylhexyloxy)(3″,7″‐dimethyloctyloxy)benzene]‐5‐methoxy‐1,4‐phenylenevinylene} (EDMP‐PPV), an
We investigate the quasi-particle conformational defects (excitons, polarons and bipolarons) in phenylene vinylene oligomers (PVOs) consisting of up to 12 repeat units. The conformations are determined by minimisation of the total Hartree-Fock energy calculated at 3-21G level. The Hartree-Fock calcu
