    • 3,5-Dicarboxy-substituted arylureas (and related esters) are poor materials for comparison since these esters prevent dimerization through steric "shielding". Modeling with the aryl rings aligned in-plane with the urea carbonyl group clearly showed that the ester substituents of one urea engender destablizing/unfavorable van der Waals interactions with a second 3,5-dicarboxyurea ester before the carbonyl group of one molecule is close enough to the NH groups of a second urea molecule for intermolecular self-quenching.
