摘要：
A merocyanine dye with an outstandingly large dipole moment of 14 Debye affords thin-film transistors with 0.18 cm(2)V(-1)s(-1) hole mobility and a 10(6) on/off ratio. These results suggest that molecules that lack symmetry and possess large dipole moments can perform excellent charge carrier transport contrary to established molecular semiconductor design strategies.
