We will focus on an amphiphilic surfactant-templating approach to synthesize ordered mesoporous polymers and carbon frameworks. A family of ordered mesoporous organic polymers and carbon solids are simply achieved by using resols as precursors, followed by a thermopolymerization process, then carbonization. The mesoporous polymers have a large uniform mesopore, high surface areas (2500 m2/g) and large pore volume (~ 2.0 cm3/g). The scale-up synthesis can be carried out, kilogrammes of ordered mesoporous carbons are easily obtained for applications in catalysis and electrochemical supercapacitors. We will also show some recent results about the applications of mesoporous molecular sieves on catalysis, water purification and electronic energy storage, especially for bio-applications.
