Hydrogen-bonded organic framework membranes (HOFs) have promising application prospects, but are currently mainly used for scientific research

Hydrogen bonded organic framework membranes (HOFs membranes), also known as supramolecular organic framework membranes, are composed of organic or metal-organic building units connected through intermolecular forces such as hydrogen bonds, π-π interactions, van der Waals forces, and electrostatic interactions. crystalline material. HOFs materials can be divided into carboxylic acid HOFs, diaminotriazine HOFs, pyrazole HOFs, pyridine HOFs, imidazole HOFs, binary classification HOFs and others, among which carboxylic acid HOFs, diaminotriazine HOFs The most widely studied.

HOFs membrane is a new type of porous framework material with periodic structure. Its metal-free characteristics give it good biocompatibility and low cytotoxicity. With its unique advantages, HOFs membrane has many applications in gas adsorption and separation, drug delivery, proton conduction, It shows good application prospects in the fields of electrode materials, fluorescence sensing, electrochromism, organic structure determination, environmental protection and biological applications.

HOFs membrane is a type of organic framework membrane. Compared with other organic framework membranes such as covalent organic framework membranes (COFs membranes) and metal-organic framework membranes (MOFs membranes), HOFs membranes have mild synthesis conditions, high crystallinity, and ease of use. It has the advantages of repair and regeneration and good solvent processability. After more than ten years of development and accumulation, my country’s HOFs membrane research has made great achievements. However, compared with MOFs membranes and COFs membranes, the development of HOFs membranes is still very lagging behind.

According to the “2022-2026 Global Hydrogen Bonded Organic Framework Film (HOFs) Industry In-depth Market Research and Key Area Research Report》shows that HOFs membranes have many advantages, but due to weak hydrogen bonding forces and poor directionality, the development of HOFs membrane materials is greatly restricted. At the same time, due to the difficulty of synthesis technology and high synthesis costs, my country’s HOFs membranes have not yet achieved large-scale implementation. For commercial applications, HOFs membranes on the market are mainly used for scientific research.

In recent years, HOFs membranes have attracted more and more attention from enterprises and institutions. In China, institutions including Fujian Normal University, Chinese Academy of Sciences, Shanxi Clean Carbon Research Institute, Tianjin University, etc. are engaged in the development of HOFs membrane structures. and functional applications. As research continues to deepen, HOFs membranes that can still maintain a crystalline structure under conditions such as strong acid, strong alkali, high temperature, and boiling water are gradually developed. At the same time, as manufacturing costs decrease in the future, HOFs membranes will be used in the field of CO2 separation and adsorption. It will go deeper and contribute to carbon neutrality.

Industry analysts said that hydrogen-bonded organic framework membrane is a new type of porous framework material. With its unique structure and performance, HOFs membrane It has shown great application prospects in fields such as gas adsorption and separation, drug delivery, fluorescence sensing, and biological applications. However, currently, due to technology and cost constraints, HOFs membranes in my country are mainly used for scientific research, and large-scale applications have not yet been achieved in other fields. In the future, as research continues to deepen and production costs decrease, the HOFs membrane market will have broad room for development.
