A Novel Class of π-Electron Dendrimers for Thermally and Morphologically Stable Amorphous Molecular Materials

Abstract

Functional materials for organic light-emitting diodes (LEDs), in addition to exhibiting the qualities listed in the previous article, should also be thermally and morphologically stable and not crystallize even above the glass transition temperature. The synthesis and properties of hyperbranched π-electron systems (such as that in the Figure) fulfilling these condition are presented, together with their unique multiredox properties.
