perylene diimides have been of great interest due to their unique optical and photophysical properties.But the manipulation of superlong

Dstructure of perylene diimides
however
is still a challenge.In this paper
superlong microfiber of bis(n-butyl) substituted perylene diimide(1) has been obtained by solvent evaporation method.FESEM and TEM micrographs indicate that the microfibers are 1~2 μm wide and several hundred micrometers long.XRD measurement demonstrates that the walls of the microfiber are arranged in highly ordered nanoscopic structure.Driving force for the formation of microfiber has been proposed
i.e.
cooperation of solvophobic effect for molecules(1) and π-π stacking interaction between the perylene diimide cores.The effect of the closely packed structure on its photophysical behavior is demonstrated by the UV-Vis absorption and fluorescence spectra.
