| Summary: | Membrane separation technology is a highly efficient and energy saving alternative for many industrial processes. The development of high-performance membrane materials is the prerequisite and key to membrane separation application. Porous organic molecular materials are an emerging subclass of porous materials. They are composed of discrete molecules linked by weak non-covalent interactions between molecules, and can be assembled into modular structures with structural diversity. Representative examples include macrocycles, porous organic cages (POCs) and hydrogen-bonded organic frameworks (HOFs). Compared with various other porous materials, one unique feature of porous molecular materials is their good solution processability, which makes them easy to cast from solutions to form porous membranes, or to fabricate composite materials. Most porous organic molecular materials possess high thermal, chemical, and moisture stability and maintain their porosity under critical conditions, making them highly appealing candidates for diverse membrane applications. In this review, we aim to provide a summary of recent advances in the fabrication of membranes covering the most representative porous organic molecular materials. More importantly, the latest applications of these membranes in gas separation, ion separation, water treatment and desalination, and proton exchange in fuel cells are discussed and highlighted. Research challenges and future directions are also briefly discussed, devoted to providing guidance for the future design and development of high-performance separation membranes.
This mini-review summarises the recent advances in separation membranes based on porous organic molecular materials, an emerging subclass of porous materials. |

During her master studies, she focused on the construction of porous organic cages and their applications. In August 2022, she joined Prof. Liu's group as a research assistant in ZJU-Hangzhou Global Scientific and Technological Innovation Center. Saisai Yu completed her Master's degree from the Hangzhou Normal University in June 2022. Currently, she is a PhD student under the supervision of Prof. Ming Liu in chemistry, Zhejiang University, China. Her current research interests are focused on the fabrication and application of membranes based on porous organic molecules. Ming Liu received his PhD degree in chemistry in 2009 from Department of Chemistry, Zhejiang University, China. Then he worked as a postdoctoral fellow in CNRS-East Paris Institute of Chemistry and Materials Science for one year, before joining Prof. Andy Cooper's group in University of Liverpool as a research associate in 2011, working on developing functional organic cages towards real-world applications. In Oct 2021, he moved to Department of Chemistry, Zhejiang University as an assistant professor. His current research is focused on the rational synthesis of molecular materials for pollution treatment and clean energy solutions by combining the tools of supramolecular chemistry, solid and computational design. Yuanhan Liu received his Bachelor degree of Chemistry from Nanchang University in 2022. He is now pursuing his Master degree of Chemistry in the laboratory of Prof. Ming Liu, Zhejiang University, China. His current research interests are focused on the capture and detection of greenhouse gases using functional porous materials. |
