a Synthesis of catechol-containing networks and a triethylsilyl protected catechol group (CAT) cluster network-formation chemistry; b schematic representation of the silyl protective group’s cleavage and subsequent iron complex formation and a test specimen swelling during the process; c Raman spectra of protected (blue), deprotected (orange), and iron-treated (black) catechol-containing networks, which is confirm iron-catechol coordination; d SAXS and WAXS of the dry networks. SAXS shows broad peaks for the deprotected (orange) and iron-treated (black) networks. WAXS peaks result from interatom matrix scattering
