It is shown, for the first time, that small (ca. 2 nm) and stable platinum nanoparticles can be easily obtained in one step through visible light irradiation of a host-guest inclusion complex between beta-cyclodextrin and platinum acetylacetonate in a water solution. The exclusive control of the reaction by an external trigger, the removal of the undesired reaction products without any manipulation of the sample, and the absence of ionic repulsions between the metal nanoparticles represent the main remarkable advantages offered by this synthetic methodology.
首次表明，通过在水溶液中对β-环糊精与乙酰丙酮铂之间的主客体包合物进行可见光照射，可一步轻松获得尺寸小（约2纳米）且稳定的铂纳米颗粒。该反应由外部触发因素进行独家控制，无需对样品进行任何操作即可去除不需要的反应产物，并且金属纳米颗粒之间不存在离子排斥，这些都是这种合成方法的主要显著优点。
