The pore size of zeolite A could be tuned by different metal ions
The first POF with charged skeletons was demonstrated by Li et al. [

]. A qua-
ternary phosphonium and tertiary phosphorus functionalized microporous polymer
was obtained using tetrakis(4-chlorophenyl)phosphonium bromide as monomer
via nickel(0)-catalyzed Yamamoto-type cross-coupling reaction (Fig.

a). The
resulting product showed high stability, indicated by treatment in water, base, and
acid. The apparent surface areas of the sample could be tuned by exchanging the
