Project A2 aims at preparing highly ordered tunable block copolymer films which shall serve as mesoporous templates for specific immobilization and spatial positioning of molecular catalysts from project area B either at the pore bottom or at the pore walls. Templates with pore sizes between 20 and 10 nm shall be obtained from cylindrical and cocontinuous morphologies by using a combination of controlled polymerization and template creation by self-assembly and selective etching processes. Electrochemistry shall be applied as a probe technique to identify porosity and tortuosity of the mesopores. The project will help to elucidate confinement effects in molecular heterogeneous catalysis.

A2项目的目标是制备高度有序的可调嵌段共聚物薄膜，作为介孔模板，用于特定固定和空间定位来自项目B区域的分子催化剂，无论是在孔底还是在孔壁。孔尺寸在20到10 nm之间的模板应通过使用控制聚合和通过自组装和选择性蚀刻过程创建模板的组合从圆柱形和共连续的形貌中获得。应应用电化学作为一种探测技术来识别介孔的孔隙度和曲折度。该项目将有助于阐明分子多相催化中的限制效应。
