Absolute asymmetrische Synthese, Spektroskopie und Untersuchungen zum Bildungsmechanismus von chiralen, supramolekularen Farbstoffaggregaten I
Further studies regarding the formation of chiral assemblies such as helices of polymethine dyes are untertaken. Spectroscopic methods such as electron microscopy and CD-spectroscopy are used in order to gain a deeper insight into the formation of chiral supramolecular species.
