Abstract: In the field of Organic Electronics, molecular electrical doping of organic semiconductors has emerged as key strategy to improve the performance of organic (opto-) electronic devices and to extend their range of functionality. However, despite impressive success in practical applications, the fundamental processes underlying molecular electrical doping are still not fully understood to date. Notably, this is reflected in the observation that the two important classes of organic semiconductors, small conjugated molecules and conjugated polymers, exhibit a vastly different phenomenology upon doping with no satisfactory explanation put forward to date. The present colloquium provides an overview on pertinent literature and recent own work focusing, in particular, on the role of microstructure and ground-state charge transfer complex formation upon doping prototypical organic semiconductors. In the prospect of providing a unifying picture of molecular electrical doping, profound differences between the fundamental mechanisms at work in small molecular and polymeric compounds of identical chemical composition and similar microstructure are discussed.
