      abstract     = {A class of amino acid-based low-molecular-weight gelators
                      (LMWGs) was used for single and multicomponent gel studies
                      to investigate their tunable optical properties and their
                      self-assembly process. The optical properties of
                      multicomponent gels were found to be easily tuned by
                      changing the proportion of the components, varying from
                      opaque to highly transparent gels as analyzed using
                      ultraviolet–visible spectroscopy. This phenomenon allows
                      tunability without introducing another variable into the
                      system. Scanning electron microscopy, differential scanning
                      calorimetry, and small-angle X-ray scattering (SAXS) were
                      used to investigate the structures of the gels. It was found
                      that because of the structural similarities of the
                      molecules, the gelators favor coassembly packing over
                      self-sorting. The emergence of transparency was ascribed to
                      changes in the fiber diameters. Moreover, analysis of the
                      SAXS data allowed us to compare the molecular order present
                      in the gel phase with single-crystal X-ray diffraction
                      (SCXRD) data. Our analysis suggests that the packing of
                      molecules seen in the crystalline phase is translated into
                      the gel network. This reveals that the structure of the
                      crystalline phase seen through SCXRD is a useful tool to aid
                      in understanding the molecular packing in the gel phase.},
