Abstract

New polyclathrochelate derivatives were obtained using the mild one-step polycondensation reaction of an iron(II) center chelated to three polar furil dioxime side groups and doubly capped with various aryl diborate central spacers. Nitrogen adsorption measurements of the polychlathrochelates (PCL1-4) reveal a strong correlation between the intrinsic microporosity and the nature of aryl diborate spacer whose small size (PCL1) or contorted structure (PCL2) afford polymers with Brunauer-Emmett-Teller (BET) surface areas of ∼396 m²/g and ∼275 m²/g, respectively. On the other hand, the BET surface area of the polymer diminishes either when the aryl diborate spacer has free rotation axes (PCL3) or a laterally extended aromatic structure (PCL4).
