Computational study of the structure, dynamics, and photophysical properties of conjugated polymers and oligomers under nanoscale confinement

Article Abstract:

Computational simulations were used to investigate the dynamics and resulting structures of several para-phenylenevinylene based polymers and oligomers. The results showed that the nature of the solute-solvent interactions in the initial solution-phase preparation largely controls the morphology and structure.
