Efficient gelation of aqueous fluids by a novel tripodal trischolamide generates chiral hydrophobic pockets in the gel network. A yellow to green color change (see absorbance spectra) in the presence of bromophenol blue (BPBH) indicates the formation of the gel. The bound (anionic) dye (BPB − ) shows induced circular dichroism, which is indicative of a chiral environment.
