Network properties of an aggregate of perylene bisimide based molecules — •Carlo Di Giambattista1, Anke Leitner1, Masoud Amirkhani1, Anne-Marie Saier1, Suhrit Ghosh3, Frank Würthner3, Michael Beil2, and Othmar Marti1 — 1Institute of Experimental Physics, Ulm University, Germany — 2Institute of Internal Medicine I, Ulm University Hospital, Germany — 3Institute of Organic Chemistry, Würzburg University, Germany
Due to non-covalent binding the perylene bisimide based molecules form a network able to bind a solvent. This combination of network and solvent is a so called organogel. Organogels are excellent examples of the construction of higher order self-assembled structures from properly designed small-molecule building blocks*. Because of the type of binding we are interested in the resulting network properties. We want to compare those properties to the ones of intermediate filaments. These filaments are as well assembled by small building blocks. To gain an idea of the microscopic structure of the organogels we use atomic force microscopy. Furthermore we do rheological measurement on the phase transition as well as on the final gel.
