1,3,5-Triazine Based Microporous Organic Polymers: Synthesis and Applications

摘要

Microporous organic polymers (MOPs) are attracting increasing attention due to their potential applications in areas such as gas adsorption, separation, and heterogeneous catalysis.~1 Compared with their inorganic or hybrid counterparts, such as silica, metal oxides, zeolites, and metal-organic frameworks (MOFs), MOPs have possible advantages in terms of combining wide synthetic diversity with reasonable chemical and thermal stability.~2 1,3,5-Triazine is an interesting building unit with high electron deficiency and spatial coplanarity.~3 In this paper, we will report synthesis and characterizations of two sets of triazine-based MOPs, including conjugated microporous polymers (CMPs)~4 and covalent triazine-based frameworks (CTFs)~5 types. Comparison of synthetic methods and gas sorption properties with previously reported MOPs and some other unique properties arising from the incorporation of the triazine unit will be shown. Potential applications of these porous materials on optoelectronic fields and photocatalysis will also be reported.
