摘要

结晶固态中的分子动力学通常受到密集晶体环境的限制，这为控制固态材料的物理性质提供了机会。在这项研究中，我们展示了一种中性晶体分子转子，其特点是对位亚苯基转子被 N-heterocyclic carbene 配体包裹，并通过 C-Au-C 旋转轴连接。单晶 X 射线衍射研究以及变温固态 2H NMR 自旋回波测量证实，对位苯分子在固态下具有 180° 2 倍旋转动力学。

Solid-state Dynamics of Binuclear N-Heterocyclic Carbene Au(I) Rotor with para-Phenylene Rotator

Molecular dynamics in the crystalline solid state, typically constrained by a densely packed crystal environment, may offer opportunities to control the physical properties of solid-state materials. In this work, a neutral crystalline molecular rotor featuring a para-phenylene rotator encapsulated by N-heterocyclic carbene ligands and connected via a C-Au-C rotational axis is presented. Single-crystal X-ray diffraction studies, along with variable-temperature solid-state 2H NMR spin-echo measurements, confirm the presence of 180° 2-fold rotational dynamics of the para-phenylene moiety in the solid state.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
