Charge transport, photovoltaic, and thermoelectric properties of poly(2,7-carbazole) and poly(indolo[3,2-b]carbazole) derivatives

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.
