Doping is an effective method to improve the carrier densities and charge transport capabilities of organic semiconductors. In recent years, n-doping of organic semiconductors via Lewis base anions has attracted much attentions of researchers, which takes place under mild condition and controllable fashion, hence exhibiting broad applications in optoelectronics. This perspective focuses on discussing the mechanism of anion-induced electron transfer to semiconductors, summarizing its recent progresses in interfacial materials and doped active layers for optoelectronic devices, as well as analyzing the future development of this field.

Key words: Lewis base anions, n-doping, anion-π interaction, interfacial materials, dopant
