The rational assembly of monomers, in principle, enables the design of a specific periodicity of polymeric frameworks, leading to a tailored set of electronic structure :properties In :these solid-state, materials. The further development of these emerging :systems requires,:a combination of both. experimental and theoretical studies.: Here,. We : investigated the electronic Structures of two-dimensional polymeric frameworks based, on triazine and benzene rings by means of electrochemical techniques. The experimental :density of states was obtained, from quasi-open-circuit voltage measurements: through a galvanostatic intermittent titration technique, which we show to be in excellent agreement with, first-principles calculations, performed for two- and three-dimensional structures, of these polymeric frameworks. These findings suggest that the electronic properties depend not only on the number of stacked layers but also on the ratio of the different aromatic rings.
