Low-temperature formation of self-assembled 1,5-diaminoanthraquinone nanofibers: Substrate effects and field emission characteristics

► Using a simple low-temperature (42 °C) process to fabricate organic nanofibers. ► Vertically aligned 1D DAAQ structures growing preferentially on low-WCA surfaces. ► DAAQ nanofibers possessed unique anti-degrading field emission characteristics.
