An approach based on N-heterocyclic olefins as novel organopolymerization catalysts is employed to synthesize triblock copolyethers in a highly controlled manner (ABA- and BAB-type, A = poly(ethylene oxide), B = poly(propylene oxide)). These copolymers will be used as tailored structure-directing agents to control the pore size of ordered mesoporous carbons resulting from a self-assembly process (targeted diameter: 2-10 nm). Variations in the degree of surface hydroxylation will then enable the independent assessment of the parameters “pore size” and “pore wall polarity” for catalysis. The introduction of functional groups exclusively inside pores will be realized by the application of macromolecular reagents.

以N-杂环烯烃为新型有机聚合催化剂，以高度可控的方式合成了三嵌段共聚醚(ABA和BaB型，A=聚环氧乙烷，B=聚环氧丙烷)。这些共聚物将被用作定制的结构导向剂，以控制由自组装过程产生的有序介孔碳的孔径(目标直径：2-10 nm)。表面羟化程度的变化将使“孔大小”和“孔壁极性”的催化参数的独立评估成为可能。只有在孔内引入官能团将通过应用大分子试剂来实现。
