| Abstract | p- or n-Dopants have played significant roles in the improvement of organic electronic devices through the controllable doping of organic semiconductors. However, there has been little study of air-stable n-dopants under ambient conditions with strong doping capability due to the low electron affinities of organic semiconductors. Herein, a 1,4-dihydropyridine-based derivative is designed and facilely synthesized as an efficient n-dopant. The doping process is systematically investigated by UV-vis-NIR spectroscopy in solution and ultraviolet photoelectron spectroscopy in the solid state. Excellent conductivities are obtained for a variety of doped n-type semiconductors via a simple solution process without further treatment, suggesting a broad class of 1,4-dihydropyridine derivatives could be used as n-dopants in future organic electronic devices. |
