Thermogravimetric analysis (TGA) has been widely used as a tool to characterise the composition of materials such as Metal‐Organic Frameworks (MOFs). However, given their multifunctionality and structural complexity, examples of detailed methodologies for the exact calculation of the composition of complex MOF structures and MOF composites are lacking in the literature. Herein, we introduce a new straightforward methodology – based on the experimental ratio between the mass of a structure and its residue – for the exact calculation of the composition of almost any MOF material. We provide a detailed guide for the application of our methodology to different MOF materials, including MOFs in which multiple components decompose fully or partially within the same temperature range as the ligand, and diverse MOF composites, alongside with theoretical calculations demonstrating the exact mathematical determination. The methodology presented here can also be applied to many materials beyond MOFs.

精确测定多功能金属有机骨架材料成分的综合热重分析多面方法

热重分析（TGA）已被广泛用作表征材料成分的工具，例如金属有机骨架（MOF）。但是，鉴于它们的多功能性和结构复杂性，文献中缺少用于精确计算复杂MOF结构和MOF复合材料组成的详细方法的示例。在这里，我们引入一种新的简单方法-基于结构质量与其残渣之间的实验比率-可以精确计算几乎所有MOF材料的成分。我们提供了将我们的方法应用于不同MOF材料的详细指南，包括MOF中多种成分在与配体相同的温度范围内完全或部分分解，以及各种MOF复合材料，理论计算证明了精确的数学确定。这里介绍的方法还可以应用于MOF以外的许多材料。
