主要描述了通过氨基酸分子自组装来制备四种不同形貌的介孔硅材料,并通过常用的检测仪器:电子显微镜进行结构解析。已经发现:(1)通过改变反应温度从0,10,15到20°C,可以制备得到不同形貌的介孔材料,即类似于蛋白质分子的螺旋飘带,空心球,飞碟状和手性棒状形貌的二氧化硅介孔材料;(2)在螺旋飘带和空心球形貌材料中介孔孔道排列是无序的,而在飞碟和手性棒状材料中介孔孔道是高度有序排列的;(3)螺旋飘带形貌的材料是纯左手的,而手性棒状形貌的材料是右手过剩的介孔材料。该研究将为在分子水平合成手性材料提供一种新的方法。
Mainly through the self-assembly of amino acid molecules to prepare four different morphologies of mesoporous silica materials, and through the commonly used detection equipment: electron microscopy structural analysis. It has been found that: (1) mesoporous materials with different morphologies can be prepared by changing the reaction temperature from 0, 10, 15 to 20 ° C, ie helical ribbons similar to protein molecules, hollow spheres, flying saucer and chiral sticks Morphology of silica mesoporous materials; (2) Spiral ribbons and hollow spherical topography material mesopores arranged in a disorderly manner, and in UFO and chiral rod materials mesoporous channels are highly ordered; ( 3) The material of the spiral streamer topography is purely left-handed, while the material of the chiral rod topography is the excess mesoporous material in the right hand. This research will provide a new method for the synthesis of chiral materials at the molecular level.
