By utilizing a porphyrinic zirconium-based MOF installed with electron-donating graphene quantum dots (GQDs) that was published in our recent study as a demonstration, significantly distinct electronic properties can be observed between the locations with and without the GQD-porphyrin donor-acceptor pairs. Such an STM technique is thus considered as a powerful tool to probe the spatial uniformity in electrical conductance and investigate the origins of conductivity for a range of conductive MOF-based materials. ? 2020 American Chemical Society. |
