Abstract:
The growth of adenine on Au(111) from the submonolayer up to several microns film thickness is studied by combining STM and surface X-ray diffraction techniques. The study shows that adenine thin films are composed of highly textured crystallites with the reported α-adenine crystal structure in such a way that they only exhibit (001)-faces. Such faces, with chiral p2 symmetry planes, have an average size of 15 nm. Thus, the formed adenine films reported herein, which expose only chiral and biocompatible faces, might find applications such as enantioselective heterogeneous catalysts for the chemical and pharmaceutical industries.
