We report a general method to synthesize gold nanocrystal micelles with organo-silane headgroups. The method involves encapsulation of monodisperse, hydrophobic gold nanocrystals within the core of a micelle of an amphiphilic silane precursor. Formation and stability of monodisperse gold NC micelles have been confirmed using UV-visible spectroscopy and transmission electron microscopy. Self-assembly of such nanocrystal micelles through siloxane hydrolysis and cross-linking leads to an ordered array with a face-centered-cubic mesostructure.
我们报道了一种合成具有有机硅烷头基的金纳米晶胶束的通用方法。该方法包括将单分散的疏水性金纳米晶包裹在两亲性硅烷前体胶束的核内。已使用紫外可见光谱和透射电子显微镜证实了单分散金纳米晶胶束的形成和稳定性。通过硅氧烷水解和交联实现的此类纳米晶胶束的自组装导致形成具有面心立方介观结构的有序阵列。
