The porous frameworks and assemblies fields have rapidly grown due to their synthetic designability and breakthrough performances in a wide range of applications. Routine characterizations may not be enough to confirm synthetic reproducibility, and we should consider other important parameters to determine the quality of results from the final materials. It is therefore essential that data related to materials synthesis, properties, simulations, measurement methods, and fabrication techniques is reliable, repeatable, and that standard protocols be established. Additionally, important discussions such as reference frameworks and agreed metrics should be made in the community, as well as considerations for cross-lab comparisons and reproducibility during scale-up. This will help tie together the field, allowing for more accurate reporting and effective development.
This Collection shares opinions and research results for establishing standards and protocols as well as challenges and solutions that will enable reliable and repeatable reporting of porous frameworks. It will cover both crystalline and amorphous framework materials (metal–organic frameworks, covalent organic frameworks, hydrogen–bonded organic frameworks, zeolites) and porous assemblies (metal–organic cages, porous organic cages).
