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

Photon correlation spectroscopy in both polarized and depolarized geometry was employed to investigate the dynamics of a ribbon-type polymer exhibiting good solubility. In dilute solution, the translational diffusion for all examined molecular weights has confirmed the picture of wormlike chains wit
This paper reports the thermal conversion of the tetrahydrothiophene (THT)-precursor to poly(p-phenylene vinylene) (PPV). Detailed investigations of the conversion process show that the leaving groups THT and HCl do not eliminate simultaneously. Moderate temperatures ( 125 Β°C) are sufficient to elim
