Paper Abstract

Nanofibers from light-emitting organic molecules such as para-phenylenes have already demonstrated a promising application potential in nanophotonic devices and can act as waveguides or nanolasers. Here, the basic mechanisms for self-assembly of three different green- and green/blue-light emitting thiophene/phenylene co-oligomers into nanofibers are investigated. Under well defined conditions in high vacuum the molecules are deposited on cleaved mica surfaces. The effect of substrate surface energy as well as epitaxy on the overall film morphology is studied and significant differences between different co-oligomers are found.
