    • 2 after guest removal. No evidence for the self-condensation of BDBA to form COF-1 was observed from the synthesis of COF-5. The reaction of BDBA alone at 100°C was slow, and after 168 hours of heating, produced COF-1 in only 25% yield.

    • Disorder existing in these compounds arises from the stacking of the sheets, as evidenced from the line broadening in the x-ray patterns (turbostratic disorder) and is frequently observed in layered materials. The tailing to a high angle of the (100) lines points to translational faults in the xy basal planes of the structures, whereas the broadening of lines corresponding to layer stacking along the c axes [(002) for COF-1 and (001) for COF-5] indicates variances in the interlayer spacings, which is more pronounced in COF-5. The construction of the open layers in COF-1 and COF-5 has been established by spectroscopy, and analysis of their gas adsorption isotherms reveals the respective permanent micro- and mesoporosity and pore sizes near those determined from x-ray data. Despite their lack of perfect crystallinity, the investigation and use of COFs as porous materials are not precluded.
