The project aims at developing a new approach towards the immobilization of organocatalysts based on nanofibers. Polymer nanofibers and core shell polymer nanofibers containing immobilized organocatalysts will be prepared by electrospinning and by the TUFT-process (tubes by fiber templates). The catalysts will be covalently bound either at the core nanofiber or at the shell. The diameters of the fibers carrying the catalysts will be modified as well as the thickness and chemical composition of the shell material to control the reactivity and transport properties. Hyperbranched polymers will be used as carriers for organocatalysts. The catalytically active hyperbranched polymers which cannot diffuse through PPX membranes will then be confined in PPX nanotubes. The tubes can thus be regarded as nanocontainers for organocatalyts.

该项目旨在开发一种基于纳米纤维的有机催化剂的新方法。聚合物纳米纤维和核心壳聚合物纳米纤维将通过静电纺丝和簇生（通过纤维模板的管道）制备含有固定有机催化剂的核心纳米纤维。催化剂将在核心纳米纤维或壳上共价结合。携带催化剂的纤维的直径以及壳材料的厚度和化学成分将被修饰，以控制反应性和转运性能。超支聚合物将用作有机催化剂的载体。然后将无法通过PPX膜扩散的催化活性超支聚合物将限制在PPX纳米管中。因此，可以将管子视为有机催化剂的纳米核心因子。
