Orientation controlled growth of metal phthalocyanines and their optical characterization — Jan Kuhnert, •Michael Kothe, Wolfram Heimbrodt, and Gregor Witte — Faculty of Physics and Materials Sciences Center, Philipps-Universität Marburg, Renthof 5, D-35032 Marburg, Germany

Phthalocyanines in combination with metal oxides are promising materials for future electronic devices such as organic solar cells (OPV). Despite their technological importance a microscopic understanding of optoelectronic excitations in such hybrid systems has yet not been achieved. To gain deeper insight ordered model systems with well-defined interfaces are mandatory. In this contribution we have studied the interrelation of structural and optical properties of Phthalocyanine thin films that were grown onto various substrates. Their structure were studied by means of XRD, AFM while the optical properties were analyzed by continuous wave and time-resolved photoluminescence spectroscopy and absorption measurements.
