areas, open porous channels, and predictable active sites enable applications in gas separation, catalysis, electronics, and energy storage. Researchers have successfully constructed COFs with lithium storage capabilities as lithium-ion electrodes by utilizing specially designed linkers and knots that incorporate active lithium storage structures, leveraging the structural design flexibility of COFs. This has inspired scientists to explore and prepare a variety of innovative COFs for LIBs applications. However, to my knowledge, nearly all reported COFs consist of organic knots and covalently connected linkers primarily derived from fossil-based fine chemicals. Consequently, these monomers significantly hinder COF materials' green and sustainable development, highlighting the urgent need to identify sustainable sources for monomers to address this challenge.
