摘要

通过对相应的互穿晶体结构进行机械研磨处理，制备出了具有三维互穿结构的金属有机框架（MOF）玻璃。同步辐射 X 射线分析、固态核磁共振光谱和红外/阻抗光谱证明，机械研磨处理削弱了相邻网络之间的分子间氢键，同时保持了晶体状态下原有的配位键连接。玻璃态的互穿结构允许较高的分子动力学，因此与大多数已报道的 MOF 玻璃相比，这种软体玻璃具有较低的杨氏模量和硬度。

Interpenetrated Metal–Organic Framework Glass

Metal–organic framework (MOF) glass having a three-dimensional interpenetrated structure was prepared by a mechanical milling treatment of the corresponding interpenetrated crystal structure. Synchrotron X-ray analyses, solid-state NMR spectroscopy, and infrared/impedance spectroscopies support that the mechanical milling treatment weakened the intermolecular hydrogen bonds between the adjacent networks while maintaining the original coordination bond connectivity found in the crystalline state. The interpenetrated structure in a glassy state allows for high molecular dynamics, resulting in a soft bulk glass with lower Young’s modulus and hardness compared to most MOF glasses reported.

期刊介绍： The journal Chemistry of Materials focuses on publishing original research at the intersection of materials science and chemistry. The studies published in the journal involve chemistry as a prominent component and explore topics such as the design, synthesis, characterization, processing, understanding, and application of functional or potentially functional materials. The journal covers various areas of interest, including inorganic and organic solid-state chemistry, nanomaterials, biomaterials, thin films and polymers, and composite/hybrid materials. The journal particularly seeks papers that highlight the creation or development of innovative materials with novel optical, electrical, magnetic, catalytic, or mechanical properties. It is essential that manuscripts on these topics have a primary focus on the chemistry of materials and represent a significant advancement compared to prior research. Before external reviews are sought, submitted manuscripts undergo a review process by a minimum of two editors to ensure their appropriateness for the journal and the presence of sufficient evidence of a significant advance that will be of broad interest to the materials chemistry community.
