Abstract Hyper-cross-linked polymers (HCPs) contains micropores (pore size < 2 nm) within a densely cross-linked aromatic framework. For example, Lewis acid-catalyzed electrophilic aromatic substitution (i.e., hyper-cross-linking reaction) between the aromatic rings in poly(4-vinylbenzylchloride-co-divinylbenzene) (P(VBzCl-co-DVB)) arrests free volume into permanent microporosity with high specific surface area. To control the pore characteristic of HCPs, we recently reported a unique methodology based on incorporation of a trimethylsilyl (TMS) group into P(VBzCl-co-DVB). The in situ removal of the bulky TMS groups during the hyper-cross-linking reaction results in the enhanced porosity. Herein, we explore various functional groups as molecular templates to micropore creation in the HCP. By synthesizing functional group-containing styrenic monomers and hyper-cross-linking the functional-group containing precursors, we will present influence of the functional groups on the pore characteristics.
