摘要

This review describes the photodriven energy- and electron-transfer processes of the columnar perylenediimide (PDI) nanostructures for efficient light-energy conversion by employing the self-assembly models. The charge separation and the directional charge transport of the oligomers, aggregates, and one-dimensional (ID) nanostructures of PDIs have been clarified by using time-resolved transient absorption techniques. Excited states, exciton migration, and excitation energy-transfer processes were examined in the first part. The second part involves the electron hopping, photodriven electron transfer and transport events taking place within the various PDI nanostructures.
