Abstract

A fundamental precept of chemistry is that properties are manifestations of the elements present and their arrangement in space. Controlling the arrangement of atoms in nanocrystals is not well understood in nanocrystal synthesis, especially in the transition metal chalcogenides and pnictides, which have rich phase spaces. This Perspective will cover some of the recent advances and current challenges. The perspective includes introductions to challenges particular to chalcogenide and pnictide chemistry, the often-convoluted roles of bond dissociation energies and mechanisms by which precursors break down, using very organized methods to map the synthetic phase space, a discussion of polytype control, and challenges in characterization, especially for solving novel structures on the nanoscale and time-resolved studies.

胶体合成中的相位控制
化学的一个基本原理是,性质是元素及其空间排列的表现。在纳米晶体合成中,尤其是在具有丰富相空间的过渡金属瑀和锑化物中,对纳米晶体中原子排列的控制并不十分了解。本视角将介绍一些最新进展和当前面临的挑战。本视角将介绍掺镱和掺镍化合物化学所面临的特殊挑战、键解离能的作用和前驱体的分解机制、使用非常有条理的方法绘制合成相空间图、讨论多型控制以及表征方面的挑战,尤其是在解决纳米尺度上的新型结构和时间分辨研究方面的挑战。
