Zusammenfassung
Patterning of organic compounds on a nanometer length scale is of great interest for solar applications: defined control over the donor–acceptor interface will allow design of an optimized nano-morphology promoting exciton separation and reducing charge recombination. Herein we present an imprinting technique using anodized alumina oxide (AAO) hard templates as stamps. We show an exact pattern transfer of the AAO structures into a solution processable hexa-peri-hexabenzocoronene (HBC), a discotic small molecule with acrylate moieties which is polymerized in situ. Film fabrication is realized for a variety of nanowire dimensions on square centimeter areas. The fabrication directly on conductive glass support and control over the formation of a dense barrier layer render this approach appealing for the fabrication of fully organic nanostructured photovoltaic devices.
