By using molecular twisting and bulky side group substitution, we successfully develop two deep-blue emitters, BiPI-1 and BiPI-2. These two twisted linear molecules retain the excellent photophysical and electrical properties of planar analogue and remarkably supress redshifts in solid state emission. Especially, BiPI-1 showed deep-blue emission in both solution and solid phase, and high carrier mobilities with mu h > 10(-3) cm(2) V-1 s(-1) and mu(e) > 10(-3) cm(2) V-1 s(-1). Standard blue electroluminescence (color purity: (0.15, 0.08)) and high device efficiency (CE: 4.62 cd A(-1), EQE: 6.18%) were observed in a non-doped OLED of BiPI-1. (C) 2016 Elsevier B.V.
