Green synthesis of olefin-linked covalent organic frameworks for hydrogen fuel cell applications

This article creates a green strategy to fabricate a highly crystalline olefin-linked pyrazine-based covalent organic framework (COF) with high robustness and porosity under solvent-free conditions. This study opens up new possibilities for the green synthesis of advanced materials and provides important guidance for the rational design and synthesis of polymeric materials for proton-exchange membrane fuel cell applications.
