Abstract
In the synthesis of CdSe nanoplatelets, the selenium-to-selenide reduction pathway is unknown. We study solvent-free growth of CdSe nanoplatelets and identify bis(acyl) selenides as key reactive intermediates. Based on our findings, we prepare a series of bis(acyl) selenides that provide useful precursors with tailored reactivity for liquid-phase syntheses of nanoplatelets.
摘要
在 CdSe 纳米板的合成中，硒到硒化物的还原途径尚不清楚。我们研究了无溶剂条件下 CdSe 纳米板的生长，并确定双（酰基）硒化物为关键反应中间体。基于我们的发现，我们制备了一系列双（酰基）硒化物，它们提供了有用的前体，具有可调节的反应性，可用于纳米板的液相合成。
