脱氢松香基有机小分子凝胶因子的合成及其性能
Synthesis and Properties of Organic Gelator Based on Dehydroabietate Derivative
摘要
Abstract
A novel low-molecular-mass organic gelator (DBNPM) was synthesized from 12-bromine-13, 14-dinitro dehydroabietic acid methyl ester. The title compound was characterized by 1H NMR, 13C NMR, IR and MS techniques. The assembly behavior of the prepared organogelator in solution was investigated. The organogelator induced gelation in a wide variety of organic solvents. With methanol as solvent, the critical gelation concentration (CGC) of the prepared gelator was the minimum, 0. 5 g/L. But the gelatination property was the most stable in 1, 4-dioxane. Scanning eletron microscope (SEM) images indicated that the xerogels from methanol solution presented flaky structure and the xerogels from 1, 4-dioxane solution were net-like structure. Infrared spectra ( FT-IR) and XRD showed that hydrogen bond was the main driving force for the formation of organogels.关键词
