When it comes to supramolecular chemistry, the carboxylic acid group (and its conjugate carboxylate base) is one of the chemist's most flexible friends. In pairs, they act as supramolecular synthons ...
MEASUREMENTS recently carried out on mono-molecular films of β- and γ-oleananic acids and esters 1 show that these compounds occupy areas very much smaller than those which are calculated on the basis ...
