Carbazole end-capped and triphenylamine-centered starburst derivative for hole-transport in electroluminescent devices

Abstract Carbazole end-capped and triphenylamine centered starburst derivative TPA-Cz has been synthesised. An investigation into its various properties show that the derivative possesses excellent thermal and morphological stability with stable amorphous behaviour, uniform surface morphology of film (rms roughness of 1.212 nm), low oxidation potential (−5.2 eV) along with electrochemical stability, high solubility and high transparency to visible light. All these properties clearly demonstrate that TPA-Cz is a highly promising material that can be used as hole-transporting material in the electroluminescent devices.
