Abstract

Organic electroluminescent devices with improced thermal stability and good performance characteristics are reported. The hole-transport material is a novel π-electron “starburst” molecule, TCTA (see Figure), whose glass-transition temperature is increased by the introduction of a structurally rigid moiety.
