Substituted Diazadibenzoperylenes: New Functional Building Blocks for Supramolecular Chemistry This work was supported by the Ulmer Universitätsgesellschaft, the Fonds der Chemischen Industrie (Liebig grant for F. W.), and the Deutsche Forschungsgemeinschaft (Habilitandenstipendium for F. W.). We are indebted to Dr. J. Schilling for the crystal structure determination and to Dr. E. Mena-Osteritz for helpful discussions about fluorescence measurements. We thank BASF AG and Degussa-Hüls AG for the donation of chemicals and Prof. P. Bäuerle for his support.
