Abstract

In contrast to the widely used bottom-up strategy for preparing various complex nanostructures, the top-down strategy is rarely applied to generate complex nanostructures. This study reports the use of a unique combination of bottom-up and top-down processes for the time-resolved stepwise fabrication of novel photoconductive nanotubes from elaborately designed asymmetric perylene diimide molecules.
