N=8 Armchair graphene nanoribbons: solution syntheis and high charge carrier mobility

An illustration of the low optical bandgap and the high carrier mobility

Dr Xuelin Yao led a team made up of researchers from this department, the Max Planck Institute for Polymer Research, the University of Basel, the University of Tokyo and the University of Southampton, to produce this paper published in Angewandte Chemie*.


N=8 armchair graphene nanoribbons (AGNRs) were successfully snthesised in solution utilising a custom arylated polynaphthalene precursor.  The resulting 8-AGNR exhibit a noteworth near-infrared absorption profile which signifies an exceptionally low optical band gap of 0.52 eV and demonstrates a record high dc charge-carrier mobility of up to 270 cm2V-1 s-1.
