To obtain an overview of the electronic properties of all semiconducting and insulating COFs, we plot the spin-polarized absolute band edge alignment for materials with both spin-up and spin-down bandgaps greater than zero (see Figure ). This plot allows us to easily see spin-polarized conduction band minima and valence band maxima; furthermore, helping to detect which of these compounds are potential candidates for catalytic, optoelectronic, and spintronic applications.
