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.
一种具有 14 德拜（Debye）超大偶极矩的甲川菁染料为薄膜晶体管提供了 0.18 cm(2) V(-1) s(-1) 的空穴迁移率和 10(6) 的开关比。这些结果表明，与传统的分子半导体设计策略相反，不对称且具有大偶极矩的分子可以实现优异的电荷载流子输运。
