ABSTRACT
Porous organic frameworks possessing a heteroatom-rich core have led to a paradigm shift in catalysis, molecular separation, and energy applications. The heteroatom effect induced by the introduction of heteroatoms dramatically improves the performance of these materials, as evident by the superior performance of nitrogen-enriched porous frameworks in contrast with their carbon-based analogs. Triazines are a class of nitrogen-containing heterocycles that have been under the spotlight as nitrogen-enriching materials. This chapter discusses different synthetic procedures and applications of covalent triazine frameworks (CTF) which have triazine rings as a connecting unit and with no weak linkage bonds present. CTFs are promising materials having high porosity and Brunauer-Emmett-Teller surface area.
