title: Fluorescent pyrene-centered starburst oligocarbazoles with excellent thermal and electrochemical stabilities.
abstract: A series of pyrene-centered starburst oligocarbazoles (1-3) have been synthesized and well characterized. Based on photophysical, thermal and electrochemical studies in solutions and as thin films, all starburst molecules reveal a sky blue emission with a high efficiency (Φ(F) = 0.99-0.81) and excellent thermal and electrochemical stabilities. As OLED materials, these superior properties are helpful to enhance device stability and lifetime.
