High photo- and electroluminescence efficiencies of ladder-like structured polysilsesquioxane with carbazole groups

Abstract

Ladder-like structured polysilsesquioxane with carbazole groups showed unexpected high photo- and electroluminescence efficiencies both in solution and solid states due to its rigid silicone ladder structures, which efficiently isolated the carbazole groups and thus suppressed their excimer formations by inter- and intramolecules.
