摘要

Two novel triphenylamine-decorated twistacenes SNPy and DNPy have been synthesized and characterized. Both of them display bright blue luminescence with high quantum yields in dichloromethane and as thin films. Based on the TGA analyses, they present high thermal stability up to 385?°C and 450 °C, respectively. The fabricated electroluminescent devices using the resulting twistacenes as emitters show blue luminescence of 2856 cd m?2 for SNPy and 4116 cd m?2 for DNPy.
