Hypercrosslinked polymers strategy

This strategy provides a facile way for the construction of hypercrosslinked polymers with unique micro-morphology structures or special performances. Dawson et al. successfully synthesized a series of MOPs containing -NH2 groups by the copolymerization of a simple amine-functionalized aromatic monomer (aniline) with benzene (Figure 4.11). Despite the non-porous network synthesized solely by aniline, the strategy of copolymerization with benzene was used to fine tune the porous properties and finally obtain the networks with apparent BET surface areas of up to 1100 m g . Moreover, the increasing aniline content in the hypercrosslinked networks led to an improved CO2/N2 selectivity of up to 49.2 1 but, as a contrast, the 100% benzene network only showed a CO2/N2 selectivity of 15.9 1.
