Nanofibers of 3.

Caption

(a) Fluorescence-mode optical microscopic image of nanofibers of 3. (b) SEM image of nanofibers of 3. (c) Normalized absorption (dashed) and fluorescence spectra (solid) of nanofibers of 3 (red) cast on a quartz slide and molecule 3 (black) in toluene (5 μM). (d) Molecular packing of 3 along different directions, where the dominant intermolecular forces driving crystal growth were identified as CH/π and electrostatic attractions. (e) Significantly twisted dihedral angles between D and A units in the molecular backbone of 3.
