Abstract
The dispersive rotation of chromophores in arbitrary disorder amorphous polymer hosts was investigated under the effect of external electric field. A reorientation transient for arbitrary disorder was evaluated and analyzed under the limiting cases of complete order and disorder. The rotational mobility of the chromophores was found to increase due to plasticization. A complete order raised the value of the diffusion constant with an increase in plasticizer content.
