Single Molecule Spectroscopy of Perylene Bisimide Derivatives and their Supramolecular Assemblies — •Erwin Lang1, Hanna Engelke1, Peter Osswald2, Rainer Dobrawa2, Frank Würthner2, and Jürgen Köhler11Experimental Physics IV, University of Bayreuth — 2Institute of Organic Chemistry, University of Würzburg

Self-assembly processes, starting from individual molecular building blocks and combining them to supramolecular structures of unbelievable variety, play a crucial role in life sciences. As a simple model system for self assembly we investigate pyridine-substituted perylene bisimide dyes, which form in the presence of cis-Pt(II) metal centres nanosized molecular squares.

Here we present a characterisation of the photophysical properties of the monomers and the molecular squares obtained by low-temperature single-molecule spectroscopy.
