W. Graupner et al., ELECTROLUMINESCENCE WITH CONJUGATED POLYMERS AND OLIGOMERS, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 256, 1994, pp. 549-554
We report on the optical properties of polymers and oligomers used in
light emitting diodes (LEDs) prepared by solution processing or vacuum
deposition. Special emphasis is put on the comparison of PPP and its
oligomers to planarized forms of PPP.
