WebbTHz spectroscopy revealed that the methoxy-substitution enhanced the photoconductivity of GNRs by a factor of ∼25%, primarily due to reduced charge effective mass following the edge functionalization, in agreement with DFT results. These results indicate the significant influence of edge functionalization on the electronic band structures of GNRs.
