Organic Thin Films and Interfaces

Scientific profile

Our research focuses on the supramolecular control of mechanical, photonic and electronic properties in thin films and interfaces and the derivation of corresponding structure-property relationships. In order to generate supramolecular structures in a controlled way, the group uses and develops techniques of interface assembly, mainly the Langmuir-Blodgett and related techniques, and characterizes the molecular thin films with sensitive methods, e.g. photothermal deflection spectroscopy. The films, which are tailor-made in their supramolecular, mesoscale and morphological structure, address a wide range of mechanical, photonic and electrical applications from membrane technology to sensors and optoelectronics.

Selected Research Topics

  • Development of an in situ procedure for the study of self-assembly and self-healing of monolayers
  • Characterization of intermolecular binding energies using Langmuir-Blodgett hysteresis experiments
  • Supramolecular variation of LUMO energies (around 120 meV for fullerenes) and provocation of H and J aggregates using the Langmuir-Blodgett technique
