The synthesis of nanoparticles has experienced a huge development over the past 20 years. However, this development has remained relatively limited to a few classes of nanomaterials such as iron oxides, semi-conducting oxides, plasmonic nanoparticles (essentially Au) and quantum dots. In these cases, a physical chemistry approach and standard recipes allow a good control of the size and shape of the resulting nano-objects. However, organometallic precursors have emerged as an important class allowing the preparation of a large variety of nano-objects, concerning a large number of elements and displaying a clean and controllable surface and therefore good physical and chemical properties. This perspective article is mostly devoted to the research efforts carried out by our group on the search for new classes of precursors and on the importance of knowing their exact structure and the molecular chemistry involved prior to the fabrication of the nano-objects.
纳米粒子的合成在过去的 20 年中经历了巨大的发展。然而，这种发展相对局限于少数几类纳米材料，如氧化铁、半导体氧化物、等离子体纳米粒子（主要是金）和量子点。在这些情况下，物理化学方法和标准配方可以很好地控制所得纳米物体的尺寸和形状。然而，有机金属前体已经成为一个重要的类别，允许制备各种各样的纳米物体，涉及大量元素，并具有清洁可控的表面，因此具有良好的物理和化学性质。本文主要介绍了我们小组在寻找新的前体类别以及在制造纳米物体之前了解其确切结构和涉及的分子化学方面所做的研究工作。
