In this paper we present the fabrication of large arrays of free-standing nanorods composed of a novel cross-linked siloxane-derivatized tetraphenylbenzidine (TPD) derivative on conductive substrates by applying a template-assisted technique. For the fabrication of the nanorod arrays we utilized nanoporous anodic aluminum oxide (AAO) templates. Vertically aligned and non-collapsed on conductive substrates and composed of a hole-conducting trimethoxysilane-substituted tetraphenylbenzydine derivative (DTMS-TPD) have been prepared. Because of good resistance against organic solvents and the highly-ordered two-dimensional nanostructure, which provides a larger interface, these nanorod arrays made of cross-linked DTMS-TPD have the potential to find application for building up well-ordered interpenetrating p-/n-type active layers for photovoltaic devices.
