    • Aggregation effects on the structure and optical properties of a model PPV oligomer 

      Collison, Christopher; Treemaneekarn, Varaporn; Oldham, W.; Hsu, John; Rothberg, Lewis (Elsevier: Synthetic Metals, 2001-03-15)
      We report the effects of solvent-induced aggregation on photoluminescence spectra, decay dynamics and quantum yield in trimers of MEH-PPV and compare these to analogous experiments on the high molecular weight polymer. ...

    • Aggregation quenching of luminescence in electroluminescent conjugated polymers 

      Jakubiak, Rachel; Collison, Christopher; Wan, Wai Chou; Rothberg, Lewis; Hsieh, Bing (The American Chemical Society: Macromolecules, 1999-04-08)
      We report measurements of photoluminescence from films of a soluble phenylenevinylene polymer that has prospective importance as the emissive material in light-emitting diodes. We show unambiguously that there is long-lived ...

    • Conformational effects on the photophysics of conjugated polymers: a two species model for MEH-PPV spectroscopy and dynamics 

      Collison, Christopher; Rothberg, Lewis; Treemaneekarn, Varaporn; Li, Yi (The American Chemical Society: Macromolecules, 2001-03-27)
      We report transient and steady state photoluminescence results along with absorption and NMR data to support the existence of two distinct morphological species in MEH-PPV solutions. NMR data provide evidence for the close ...

      Samuel, I.; Rumbles, G.; Collison, Christopher; Moratti, S.; Holmes, A. (Elsevier: Chemical Physics, 1998-02-01)
      We report a study of time-resolved photoluminescence (PL) in a cyano-substituted poly(p-phenylenevinylene). We have investigated the effect of excitation and emission wavelength as well as solvent on the PL. We observe ...
