Abstract
This review highlights recent advances made with poly(2,7‐carbazole) and poly(indolo[3,2‐b]carbazole) derivatives in organic field‐effect transistors, photovoltaic cells, and thermoelectric devices. For each of these applications, several examples of the structure‐property relationships occurring in these classes of materials are discussed. For instance, this review shows that the excellent hole transporting properties of poly(2,7‐carbazole)s make them highly promising materials for p‐type transistors and solar cells. Moreover, the chemical and physical properties of these N‐containing conjugated polymers can be easily tuned to meet the different requirements to set‐up the so‐called plastic electronics where micro‐electronic devices could be printed onto various substrates.
