Abstract
Liquid-liquid interfaces provide an ideal platform for nanocrystal synthesis and assembly due to the unique physicochemical properties, such as high surface tension, dipole of oriented water molecules at interfaces, spontaneously acquired negative charge, gradient distributed ions and molecules etc. In most cases, liquid-liquid interfaces are oil-water interfaces which have been intensively applied to synthesize large 2D nanostructures. A disadvantage of using oil-water interfaces for materials synthesis is the narrow temperature window due to the relatively low boiling point of water phase (100 C). Therefore, reactions require high temperature are not able to take place at oil-water interfaces. Study of interfacial nucleation and crystallization were also limited in a narrow temperature range. Therefore, in this thesis, the room temperature ionic liquids (RTILs) and ethylene glycol (EG) which have higher boiling point are used to form the liquid-liquid interfaces, extending the reaction temperature window up to ~180 C for gold (Au) crystal synthesis and crystallization mechanism study.
