The promise of low-cost processing and flexible circuitry has driven intense research in carbon-based electronics. The performance of carbon-based materials can be effectively tuned by the application of redox reagents dopants, through increasing the conductivity and decreasing the injection barrier. Two ferrocene and two ruthenocene substituted compounds (1-4) were investigated with X-ray single crystal analysis. These compounds represent a series of new benzimidazole-based n-type dopants, which can be used to dope a variety of semiconductors for organic thin-film transistors (OTFTs) and other applications. They react (faster than similar air-stable organic dopants) with a variety of electron-transport materials, including fullerenes and perylene diimides, to form the corresponding radical anions and monomeric benzimidazolium cations. Studied compounds are proved to be effective dopants for a variety of vapor- and solution-processed materials.
