Organic-metal and organic-organic interfaces play crucial roles in charge injection in, and transport through, organic thin film devices. Their electronic structure, chemical properties and electrical behaviour must be fully characterized and understood if engineering and control of organic devices are to reach the levels attained for inorganic semiconductor devices. Recent fundamental, as well as device, work has demonstrated that electrical doping provides a very interesting way to improve carrier injection into molecular films and, eventually, control molecular level alignment at their interfaces. This brief review emphasizes the current understanding of the effects of doping on organic interfaces.
