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固定化的新方法。聚合物纳米纤维和核壳聚合物纳米纤维含有固定化的有机催化剂将通过静电纺丝和通过TUFT工艺（管纤维模板）制备。催化剂将在核壳或壳处共价结合。携带催化剂的纤维的直径以及壳材料的厚度和化学组成将被修改，以控制反应性和传输性能。超支化聚合物将用作有机催化剂的载体。不能通过PPX膜扩散的催化活性超支化聚合物将被限制在PPX纳米管中。因此，管可以被视为有机催化剂的纳米容器。
