Herein, we report a new method for developing a porous network into polymeric materials. A simple thermal process of non-porous melamine-based polymers in aprotic solvents, namely solvent-assisted curing, affords porous characteristics with exceptionally high surface area. Swelling and exclusion of small molecules from the polymeric structure with the solvent promotes the formation of inner pores. Therefore, the physical property of porous polymers can be controlled by adjusting the monomer stoichiometry ratio that affects the degree of crosslinking. In addition, tailoring the shape of precursor materials provides the porous polymer in a variety of forms such as particles and a monolith.
