Three families of mono-substituted sucrose fatty acid esters were prepared by enzymatic and classical synthetic procedures, and their self-assembly and self-organizational properties were investigated by thermal polarised light microscopy, differential scanning calorimetry and X-ray diffraction. The properties were evaluated as a function of the fatty acid chain length. For the lower homologues of the
通过酶促和经典合成方法制备了三族单取代蔗糖脂肪酸酯,并通过热偏振光显微镜,差示扫描量热法和X射线衍射研究了它们的自组装和自组织性质。评估性能作为脂肪酸链长的函数。对于系列的较低同系物,发现了柱状液晶堆叠结构,而对于较高的同系物,则以层状相为主。提出了一种柱状堆积排列的模型,该模型由分子的独特排列组成,这可能导致在色谱柱的疏水内部和亲水外部之间形成多个内部离子通道。
