A new terfluorene hetero-analogue, 3TTP, introducing pyridinylthiophene as the conjugated constituent, exhibiting promising properties has been synthesized. The OLED device adopted 3TTP as emitting dopant incorporating its parent T3 as host displayed a sky-blue electroluminescence with a good performance (EQE = 3.9%). The blue device was further combined with rubrene gave a white OLED with a splendid EQE of 3.9% and high color purity [CIE = (0.31, 0.35)].
