Single-Molecule Spectroscopy of Individual Perylene Bisimide Derivatives — •Hanna Engelke1, Erwin Lang1, Peter Osswald2, Frank Würthner2, and Jürgen Köhler1 — 1Experimental Physics IV, University of Bayreuth — 2Institute for Organic Chemistry, University of Würzburg
We present a detailed characterisation of the photophysical properties of three different perylene bisimide derivatives. The probe molecules have been immobilized in a Shpol’skii matrix of hexadecane and were investigated by single-molecule spectroscopy at cryogenic temperatures. Exploiting single-molecule techniques, we compare the three derivatives as regards their saturation behaviour, triplet substate kinetics and fluorescence quantum yield.
