Abstract

A highly π-acidic dipyridinium-naphthalene diimide acceptor shows anion–π interactions with halides and PF6−. Lewis basicity and redox potential of the anion affect the chemistry, and photophysical and electrochemical properties, as well as both ionic and electrical conductivities. Our results provide insights into doping, degradation and ion transport mechanisms in organic n-type semiconductors.
