• fibers [14] because the powder diffraction patterns of the neat ODA-C powder and the SAFIN structures in the gel are the same (i.e., the ODA-C molecules pack in the same morph in the absence and presence of silicone oil). Flow curves. The rheological behavior of the gels was explored over a torque range

XRPD, molecular modeling and packing model The X-ray powder diffraction (XRPD) pattern of (S,S)-1b xerogel showed strong peaks corresponding to periodic distance d of 16.1 and 13.4 Å and a weaker peaks corresponding to d’s of 15.1 and 8.6 Å
