3.2.3 Metallization of Reactive Site
For POFs, one of the most promising applications is in the field of gas storage
and separation. To enhance gas uptake, porous materials should have strong inter-
actions with gas molecules. Several strategies in the literature have been devel-
oped to enhance interactions between porous materials and gas molecules via the
control of pore sizes, incorporation of polar functional groups, or the introduction
of open metal sites into the porous networks.
