英文摘要Synthesis of N-stearoyl-L-glutamic acid (C-18-Glu), a new gelator with multi-H-bonding sites, and N-stearoyl-L-glutamic diethyl ester (C-18-Glu-2ES) were reported. The previously reported synthetic route of C-18-Glu is that stearoyl chloride was dropwise added into disodium L-glutamate solution in a mixture of acetone and water (J. Am. Oil Chem. Soc. 1972, 49, 157 and Langmiur, 2001, 17, 1317). However, our experimental results indicated that one of the by-product HCl, could catalyze the yielded C-18-Glu to react further with L-glutamate to give more side-products. Therefore, the further workup became more difficult and the pure C-18-Glu was difficult to be obtained. Here, we synthesized C-18-Glu by the following two routes. One is from L-glutamic diethyl ester and steanic acid using dicyclohexylcarbodiimide (DCC) as a catalyzer. The other is from stearoyl chloride and L-glutamic diethyl ester. These two synthetic routes can all give out C-18-Ghr with satisfactory characteristic data. Moreover, The gelating properties of C-18-Ghr and C-18-Glu-2ES were also investigated. C-18-Glu can gel chloroform and 1 : 1 mixed ethanol/ water, while C-18-Glu-2ES can form organogels in more solvents such as petroleum ether, hexane, acetone, ethanol, and 3:7 mixed ethanol/water. AFM images indicated that C-18-Glu self-assembled into nanowires in chloroform, while C-18-Glu-2ES into lamellar-like microstructures in 3:7 mixed ethanol/water.
