Cyanuric chloride as a linker towards the synthesis of covalent triazine polymers: a review

Covalent triazine polymers represent a promising class of materials composed of aromatic electron deficient 1,3,5-triazine repeating units. They are synthesized from different triazine monomers, where cyanuric chloride is one such monomer. It is known for its high reactivity and easy availability and has garnered significant attention due to its nitrogen-rich, stable triazine rings, and hydrophilic nature. These versatile and flexible polymers are exploited due to their stable heteroatom-rich skeletons and porous nature. This review discusses an overview of the synthesis of various porous polymers based on cyanuric chloride, along with its applicability in different sectors, especially in environment protection and energy storage. It gives an insight into the current and future perspectives for developing such polymers.
