We take here the perspective of a nanochemist on the field of colloidal nanocrystals, focusing specifically on nanocrystal synthesis. Considering the three components of a colloidal synthesis, we discuss the chemistry that occurs with precursors, ligands, and solvents. Insight into the coordination chemistry and the organic chemistry of nanocrystal syntheses brings us one step closer to a retro-synthetic analysis of a nanocrystal reaction. We also reflect on different crystallization mechanisms (either under thermodynamic or kinetic control). We consider the possibility that the different models are simply describing different experimental conditions and are not fundamentally at odds with one another. However, we do critically evaluate the use of the terms monomer and burst nucleation. Finally, we discuss good chemical practices for a nanochemist, and we try to define nanocrystal purity. This perspective will hopefully inspire researchers in colloidal nanoscience to think more about chemical equations, consider reaction by-products, and come together as a field to agree on standard reporting practices for colloidal nanocrystals.

胶体纳米晶体合成的化学注意事项†

我们在这里采用纳米化学家对胶体纳米晶体领域的看法，特别关注纳米晶体的合成。考虑到胶体合成的三个组成部分，我们讨论了与前体、配体和溶剂发生的化学反应。深入了解纳米晶体合成的配位化学和有机化学使我们更接近于对纳米晶体反应的逆合成分析。我们还思考了不同的结晶机制（在热力学或动力学控制下）。我们考虑了不同模型只是描述不同的实验条件并且从根本上不相互矛盾的可能性。然而，我们确实批判性地评估了术语单体和爆裂成核的使用. 最后，我们讨论了纳米化学家的良好化学实践，并尝试定义纳米晶体的纯度。这一观点有望激发胶体纳米科学的研究人员更多地思考化学方程式，考虑反应副产物，并作为一个领域就胶体纳米晶体的标准报告实践达成一致。
