Molecular sequential doping using conjugated polymers is a promising approach to modulate or improve electrical conductivity without sacrificing the morphology of a pristine polymer film. In article number 2005129, Hyungtak Seo, Jong H. Kim, Bong‐Gi Kim, and co‐workers develop a cascade doping strategy that realizes excellent electrical conductivity through a separated doping process using two different dopants. The first dopant provides a kinetically favorable working environment for the second dopant, through regeneration, reengagement, and replacement during the secondary doping step.
