Kurzfassung englisch:
Single molecule interference has recently reached the realm of small organic molecules of biological interest [1]. The detector in this experiment was based on electron impact ionization. Future experiments aiming at quantum wave experiments with polypeptides or proteins will require a softer and more efficient detection scheme. We therefore discuss the feasibility of various surface detection methods for use in molecule interferometry.
We study physical properties of Tetraphenylporphyrin, C44H30N4 (TPP) such as the detection sensitivity, photobleaching and molecular mobility after shadow imaging of the molecular beam under high vacuum conditions.
We present experiments with porphyrins on Quartz, HOPG and Mica investigated in fluorescence and atomic force microscopy. We discuss the use of surface probing methods as detectors in quantum interference with organic materials.
