The template‐assisted fabrication of well‐ordered interpenetrating donor/acceptor nanostruc‐tures based on polymeric semiconductors on conductive substrates is reported. Arrays of free‐standing crosslinked tetraphenylbenzidine based nanorods are fabricated utilizing sacricial AAO templates. TEM conrms the obtained donor/acceptor nanostructure morphology. The embedded nanorods show no aggregation and collapse of the rods within the lm. Photoluminescence measurements reveal a more than three fold improvement in photoluminescence quenching relative to the planar bilayer architecture. The approach offers a versatile all‐solution‐based technique for the fabrication of well‐ordered bulk heterojunction lms with a large donor/acceptor interface for the application in polymer/polymer photovoltaic devices.
