title: Enhanced Structural Organization in Covalent Organic Frameworks Through Fluorination.
abstract: Here, we report a structure-function study of imine covalent organic frameworks (COFs) comparing a series of novel fluorine-containing monomers to their non-fluorinated analogues. We found that the fluorine-containing monomers produced 2D-COFs with not only greatly improved surface areas (over 2000 m2g-1compared to 760 m2g-1for the non-fluorinated analogue), but also with improved crystallinity and larger, more defined pore diameters. We then studied the formation of these COFs under varying reaction times and temperatures to obtain a greater insight into their mechanism of formation.
