| Here, we demonstrate an amphiphilic surfactant-templating approach to synthesize highly ordered mesoporous phenolic resin polymers and a direct transformation to homo- logous carbon frameworks without defect. The two novel kinds of mesoporous organic polymers and carbon solids are simply achieved by a solvent evaporation induced self-assembly using resols as precursors, followed by a thermopolymerization process, then carbonization. The mesoporous polymers have a large uniform mesopore, high surface areas and large pore volume. The polymer mesostrucutres can be easily tuned from heaxgaonl and cubic. The mesoporous carbons have zeolite-like framework structures with high surface areas (~ 1150 m2/g) and narrow pore size distribution (> 3.0 nm). The derived carbons with thick walls (~ 7.0 nm) are first example of molecular sieves which have ultra high stability in N2. |
