Abstract
Amino acid-based molecules containing a bis-urea moiety have been synthesized and demonstrated for their anion binding affinities. Compound 1c binds phosphate and sulfate with binding constants of 3.6Â ÃÂ 103Â Mâ1 and 4.3Â ÃÂ 103Â Mâ1, respectively. These molecules undergo proton transfer upon treatment with fluoride, resulting in the formation of imidazolidinediones. The crystal structure of one such diimidazolidinedione displays self-assembly through nonconventional hydrogen bonding interactions.
