摘要：

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 m(2)g(-1) compared to 760 m(2)g(-1) for 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.
