MOLECULAR MOTION DETECTOR & TRACER 

Semester project at the Hochschule Rapperswil (HSR), department of Electrical Engineering. Switzerland 1998 by Reto Zingg and Thomas Derrer. 

Aim of the MMD&T project

Verify the feasibility of automated detection and tracing of molecules in a scanning probe microscopy sequence with image processing. For this study a system of porphyrin molecules on a Au(110) substrate was chosen. Due to the asymmetric corrugation of the substrate (2x1 reconstruction of the substrate) molecular motion is confined to only one dimension at room Temperature. For the algorithm it is assumed, that the majority of the molecules will not move between two frames and that the molecules within one row can not pass each other.

Introduction and long term aim of the project

Molecular positioning of building blocks into larger supramolecular structures [1] is a key technique to construct molecular nanostructures and explore their properties. Possible applications may include data storage, nanoscale optoelectronic devices and ultrasensitive (bio)-chemical transducer elements responding to the recognition of a single molecule. Positioning at room temperature has been achieved for numerous molecule-substrate systems, especially of fullerenes (C60) on silicon, on Cu(111), and on bianthrone.
One of the key issues in this field, relevant to many applications, is the current limitation in speed to perform complex repositioning patterns. This project aims at the development of techniques for optimisation of the “human-machine” interface. Image processing and analysis have been developed to enable the automatic recognition of individual molecular units within the STM-images, and to identify the relevant molecular displacement vectors in a sequence. These procedures can then be used for performing subsequent repositioning steps and verifying the process for the formation of a predefined molecular pattern. Rigid, highly symmetrical and planar porphyrin derivatives have been chosen as a model system for such repositioning experiments.
