Noncovalent Syntheses of Supramolecular Organo Gelators

Four new organo gelators, namely, dicyclohexylammonium hydrogen cyclobutane-1,1-dicarboxylate (1), dicyclohexylammonium cyclobutane-1,1-dicarboxylate (2), dibenzylammonium hydrogen cyclobutane-1,1-dicarboxylate (3), and dibenzylammonium cyclobutane-1,1-dicarboxylate (4), have been noncovalently synthesized. Single-crystal structures of all the gelators
were determined to make an attempt to correlate their structure with their properties (gelation). The results support the conclusion
that a one-dimensional hydrogen-bonded network in the crystal structure appears to be one of the prerequisites for gelation behavior.
