Abstract

We investigated the EL characteristics of a series of dialkyl substituted polysilanes to clarify the fundamental electroluminescent (EL) properties of σ-conjugated one dimensional Si polymers. The EL properties of these polysilanes were found to be strongly influenced by branch-like defects in the Si backbone from EL spectrum measurements and the energetics of carrier injection into the polysilanes. We also demonstrated the influence of a change in conformation on the EL spectrum of dialkyl polysilane-based light emitting diodes.
