Electroluminescence in conjugated polymers

Abstract

Research in the use of organic polymers as the active semiconductors in light-emitting diodes has advanced rapidly, and prototype devices now meet realistic speci®cations for applications. These achievements have provided insight into many aspects of the background science, from design and synthesis of materials, through materials fabrication issues, to the semiconductor physics of these polymers.

Excitation Migration along Oligophenylenevinylene-Based Chiral Stacks: Delocalization Effects on Transport Dynamics

“…At the device scale, the demonstration that conjugated polymers (CPs) can be successfully exploited in light-emitting diodes, [1][2][3] field-effect transistors, 4 or photodiodes 5,6 has led to the emergence of a new area in electronics, referred to as "plastic electronics".…”

Understanding electron flow in conducting polymer films: injection, mobility, recombination and mesostructure

“…Other features (e.g., isotropy of the macroscopic mobility; propensity to charge trapping) depend strongly on the connectivity and texture (including both the 'spaghetti structure' and possible inclusions or voids). There is considerable experimental evidence that the texture is important (Bloor et al 1975, Friend et al 1999, Gao et al 1999, Nguyen et al 2000, Shi et al 2000, Whitehead et al 2000. Further features are important for electron transfer between an electrode and a molecule, or between molecules within the film.…”

Multicolor Luminescence from Semiconductor Nanocrystal Composites Tunable in an Electric Field

“…Such nanocomposites allow combining the efficient luminescence from inorganic semiconductor with good mechanical and optical properties of polymer films (Friend et al, 1999;Vanheusden et al, 1996b). Poly(4,4'-diphenylene diphenylvinylene), (PDPV) (Eg=3.0 eV) (Feast et al, 1995) is a conjugated polymer for electroluminescence (EL) in the green region (Cacialli et al, 1997 (Baranov et al, 2006;Mordkovich et al, 2003;Panin et al, 2007a;Panin et al, 2007b;Panin et al, 2007c).…”
