Temperature dependence of the electroluminescent characteristics of light‐emitting diodes made from poly(methylphenylsilane)

Abstract

Polysilanes—Si‐based σ‐conjugated polymers —have electronic structures markedly different from those of π‐conjugated polymers. The temperature dependence of the electroluminescent properties of single‐layer LEDs made from poly(methylphenylsilane) is reported and it is demonstrated that these LEDs can be used as light sources in the near UV region. Observation of electroluminescence from one of the most typical polysilanes is encouraging as it indicates that there is potential for further improvements.
