Abstract

A family of 3, 5-diaminobenzoate derivatives containing different Cbz-protected α-or β-amino side pendant chains and different aromatic-containing ester functionalities was prepared. It was found that the additional aromatic rings in the Cbz-and aromatic-containing ester moieties significantly improved the gelation properties of the resulting organogelators in aromatic solvents. Infrared and circular dichroism spectroscopy revealed that both H- ...
