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.

该项目的目标是合成孔径(50 Nm)、几何形状和形状可调的聚合物(PS和PMMA)纳米泡沫，作为分子催化的定制底物。为了实现这一目标，将研究聚合物纳米颗粒的尺寸和工艺参数对所用纳米泡沫连续色散反转原理的影响。纳米泡沫通过孔表面的羟基化来功能化。将引入环氧化物作为连接基团催化剂的锚定中心，以催化硼酸与烯酮的1，4-加成反应。金属氧化层的沉积提高了聚合物纳米泡沫相对于溶剂和高温的稳定性。
