2023年5月24日 · The chemical analysis of released compounds and the thermodynamic study of exchange equilibria provide a surprisingly detailed picture of the chemistry of the NC-ligand bond, the heterogeneity of binding sites, and the bunching of ligands on the NC surface.

2016年1月22日 · Surface ligands — molecules that bind to the surface — are an essential component of nanomaterial synthesis, processing and application. Understanding the structure and properties of nanoscale...

2021年2月26日 · Colloidal lead halide perovskite nanocrystals (NCs) have recently emerged as versatile photonic sources. Their processing and luminescent properties are challenged by the lability of their surfaces, i.e., the interface of the NC core and the ligand shell.

2021年12月30日 · The electronic, optoelectronic, and thermoelectric applications of solution-processed, inorganic ligand (IL)-capped colloidal NCs are especially promising as the performance of related devices can substantially outperform their organic ligand-capped counterparts. This in turn highlights the significance of preparing IL-capped NC dispersions.

2025年2月6日 · When a ligand is bound to a metal through a particular atom, preferably place that atom closest to the metal - e.g., [Fe(CN) 6] 3-not [Fe(NC) 6] 3-(Note: this rule is used primarily for ambidentate ligands; although IUPAC recommends that aqua ligands be written as OH 2 when the O would be closest to its coordinated metal, they are still usually ...

2024年11月6日 · 针对 NC 金属核、M-L 界面和配体壳进行精确的原子级修饰，从而实现定制的 NC 特性：（1）金属核定制：NC核可以通过共还原、模板转换和簇间反应等方法掺杂特定原子（例如Pt、Cu、S）。掺杂位置通常是特定于元素的；例如，Pt 和 Pd 占据核心中心以获得稳定性 ...

2025年3月13日 · The NC-ligand-solvent interface is critical in facilitating phase transition, including crystalization and assembly. Organic ligands are mostly used, although they also exist in other forms 45 .

2023年1月18日 · We construct an extensible numerical model to calculate the total ligand-ligand interaction energy on NCs with pure or mixed aliphatic ligands. This model not only translates NMR measurables into interaction energies but also accommodates semi-empirical predictions without relying on NMR measurements.

2016年1月25日 · Surface chemistry is a key enabler for colloidal nanocrystal applications. In this respect, metal oxide nanocrystals (NCs) stand out from other NCs as carboxylic acid ligands adsorb on their...

2015年2月6日 · The influence of ligation on electronic structure makes surface coordination chemistry critically important in NC science. Density functional theory (DFT) simulations of surface ligand interactions can be informative, but experimental structures have only recently reached sufficient accuracy to enable realistic DFT studies . Untangling the ...
