In order to defme the chemical conformation of gelator,para-hydroxy PYndinium salt of 1,2,4,5-benzene tetracarboxylic acid(defined as G1),four model compounds were prepared from para-,meta-,ortho-phthalic acid with 4-hydroxy pyridine(PHP),and 1,2,4,5-benzene tetracarboxylic acid(BTA)wim 4-pyridylcarbinol(PCB),and their ~1H NMR spectra were investigated.The single crystal of G 1 obtained directly from gelling solvent was measured,which displayed complicated hydrogen-bonded networks arising from the supramolecular synthons and other weak interactions between H_20 and the components.The powder X-ray diffraction(XrRPD) experiments were also carried out to understand the relationship between molecular packing of the bulk crystal and the gelation behavior.
