摘要：
This study reports on the gelation behaviour Of a well-known family of dipicolinic acid derivatives that lack any long aliphatic chain as substituent, The mechanism of gelation is likely to arise from the base-assisted deprotonation of the carboxylic functionality which leads to the formation of the monodeprotonated ligand as the key gelling species, The gels of aqueous DMSO are remarkably thermally resistant and stable over long periods.
