The effect of fluorine on supramolecular hydrogelation of 4-fluorobenzyl-capped diphenylalanine

Abstract

With the replacement of only one hydrogen atomby fluorine, 4-fluorobenzyl-diphenylalanine was able to form a transparent hydrogel, while benzyl-diphenylalanine did not under similar conditions, indicating the remarkable effect of fluorine on supramolecular hydrogelation.
