Engineering of Advanced Materials
One of the main goals within the EAM is the controlled fabrication of functional structures and materials from molecules. To do so we follow a bottom-up approach, in which we rely on the adsorption behavior of functional molecules, namely porphyrins, on various substrates. In the present study, 2H-tetrakis(3,5-di-tertbutyl)phenylporphyrin (2HTTBPP) has been investigated on a Cu(110) surface by scanning tunneling microcopy (STM). Due to the unusual strong molecule-substrate inter-action, high resolution imaging and thus characterization of individual porphyrins can be conducted even at room-temperature.
