Abstract

The fabrication of high-efficiency light-emitting diodes (LEDs) based on sublimed molecular films has attracted much attention in the search for materials for application in large-area flat-panel displays. Here, multilayered LEDs based on poly(methylphenylsilane), PMPS, as the hole transporting material are reported (see Figure). In contrast to polyphenylenevinylene, PMPS films exhibit a high effective mobility of holes, making the material suitable for fast switching applications.
