Gelation tests reveal that 19 salts (9 cinnamates and 10 benzoates) are moderate to good gelators of various organic fluids, including commercial fuels such as gasoline and diesel fuel. Structure−property correlation studies based on single-crystal structures of 18 salts indicate that the one-dimensional hydrogen-bonded network is indeed important for gelation. The conformational flexibility of the dibenzyl cation and various intra- and internetwork C−H···π and C−H···O interactions appear to be responsible for the stabilization of the one-dimensional network in these salts. The gel fibrils in the xerogel state for 8 salts also adopt a 1D hydrogen-bonded network, as revealed by detailed X-ray powder diffraction studies, further supporting the importance of the one-dimensional network in the gelation process. 2006-09-06 00:00:00 18 salts StructuresA series Gelation tests dibenzyl cation New Class Organo Gelator diesel fuel 10 benzoates cinnamic acids 8 salts gelation process gel fibrils xerogel state benzoic acids ammonium monocarboxylate salts
