Paper Abstract
The synthesis of molecules consisting of various combinations of phenylene and thiophene groups and the subsequent
vacuum growth of needle-shaped nanoaggregates on specific surfaces allows us a systematic investigation of
the transition between single parallel and multiple aligned needle ('nanofiber') growth. The former growth mode
is observed for blue light emitting phenylene fibers, whereas the latter growth mode appears for single crystalline
fibers made from green- and orange-light emitting oligo-thiophenes and thiophene/phenylene co-oligomers. In all
cases the tailored bottom-up growth results in strongly polarized light emission along specific surface directions.
The results are compared to those found for nanoaggregates made from less rod-like organic molecules, namely
rubrene and POPOP.
