Gelation is crucially dependent on functional group orientation and may be tuned by anion binding.
The gelation ability of a series of chiral bis(urea) gels alternates between even and odd chain length and for the even numbered spacers the rheological characteristics can be tuned by the addition of anions according to the anion binding constant.
