2 Topographic background H.C.Andersen Egeskov

3 Goal New devices on the basis of a new kind of organic nanofibers 5 µm

4 Quality factors of organic nanofibers Dimensions: height nm, width nm, length mm Brightness (efficiency 30 percent) Well-defined spectra at room temperature Huge dichroism (polarized emission) Emission into large solid angle Emission color change via modification of basis units Reproduction and alignment via self-assembly Prices

5 Examples for single color nanoscopic elements p-6p / mica MOP4 / mica p-6p + α-6t / mica, s-polarization p-6p + α-6t / mica, p-polarization α-6t / mica α-4t / mica
