Nanoporous host materials with adjustable pore size, geometry and distribution: Synthesis, functionalization and characterization (A07+)

该项目的目标是合成具有可调孔径（< 50 nm）、几何形状和形态的聚合物（PS和PMMA）纳米泡沫，作为分子催化的定制基底。为了实现这一目标，将研究聚合物纳米颗粒的尺寸和所使用的NanoFoam连续性反转分散原理的工艺参数的影响。纳米泡沫通过孔表面的羟基化而官能化。将引入环氧基团，作为带有连接基团的催化剂的锚定位点，催化硼酸与烯酮的1，4-加成。金属氧化物层的沉积增加了聚合物纳米泡沫体相对于溶剂和高温的稳定性。

Goal of the project is the synthesis of polymeric (PS & PMMA) nanofoams with adjustable pore size (< 50 nm), geometry and morphology as tailor made substrates for molecular catalysis. To achieve this goal, the influence of the size of the polymeric nanoparticles and the process parameters of the used NanoFoam Continuity Inversion of Dispersions principle will be studied. The nanofoams are functionalized via the hydroxylation of the pore surface. Epoxide groups will be introduced serving as anchoring sites for linker group-bearing catalysts catalyzing the 1,4-addition of boronic acids to enones. The deposition of metal oxide layers increases the stability of the polymeric nanofoams with respect to solvents and high temperature.
