We demonstrated the successful preparation of an imide-functionalized mesoporous polymer and nitrogen-doped mesoporous carbon with high regularity, tunable morphology, and high surface area, by using highly stable oligoimide as the nitrogen source. Oligo(amic acid)s, the precursors of oligoimide, undergo a co-self-assembly process with amphiphilic block copolymer template and transform into oligoimide under heating. Upon calcination at 350 °C the template F127 is removed without damaging the imide linkage, leading to a highly ordered polymer network with intrinsic imide functionality. Further carbonization at 600 °C allows for the formation of nitrogen-doped mesoporous carbon. This newly developed system, which exhibits a high degree of flexibility, allows precise morphological control of 2-D hexagonal and cubic mesostructures on the basis of adjustments of each component in the system. |
