About this Research Topic
The molecular approach to materials science has been demonstrated to be a promising research field for the next-generation of electronic devices due to the high versatility and tunability of synthetic chemistry. Multifunctional molecular materials are particularly interesting when exhibiting synergism or interplay between different physical properties (i.e., electrical, optical or magnetic) opening new avenues in the field of electronics.
Metal–Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs) have emerged in the past two decades as promising crystalline porous materials for gas storage and separation, catalysis, energy storage, sensing, and many other applications, due to their remarkable chemical, structural and functional versatility. Besides their inherent porosity, MOFs and COFs may also incorporate electronic functionalities such as redox activity, electrical conductivity, luminescence or magnetism, which strongly depend on the electronic nature of the selected building blocks.
Redox processes (i.e. loss and gain of electrons) have been exploited towards the preparation of electroactive materials for different technological applications. Redox activity in MOFs and COFs can be achieved by rational design of metallic nodes, organic linkers or by incorporation of redox-active guest molecules in the channels. In addition, redox activity allows to modulate their physical properties (i.e. optical, magnetic and electrical) in a switchable manner by applying different external stimuli.
In this Research Topic, we aim to cover different aspects related to redox active MOFs and COFs such as the design and synthesis of new redox-active porous materials, novel solid-state electrochemical and spectroelectrochemical techniques for their characterization, or their different applications in electronics. We welcome submission of Original Research, Review, Mini-Review, and Perspective articles on themes including, but not limited to:
• Synthesis, structural investigation, and characterization of novel multifunctional redox-active MOFs and COFs
• Investigations of switchable optical, electrical and magnetic properties MOFs and COFs
• Novel solid-state electrochemical and spectroelectrochemical techniques used for the study of charge transfer in MOFs and COFs
• Design and synthesis of novel radical-based MOFs and COFs
• Studies on stimuli-responsive (i.e. temperature, light, heat, pressure, electrical field, magnetic field, etc.) MOFs and COFs
• Applications of novel redox-active MOFs and COFs in electronics (energy storage, electrochemical sensors, etc.)
