由定向结构单体（构造）组成的微孔聚合物网络具有较高的永久表面积和孔隙率。通过选择合适的构造，可以在这种网络中引入各种功能。本文介绍了手性双酚衍生物作为新型结构物在聚合物网络中产生微孔。使用这种单体可以形成完全由对映体纯化合物组成的网络。该多孔网络可作为非对称反应的非均相有机催化剂，具有比均相反应更高的对映选择性。
Microporous polymer networks, composed of structure-directing monomers (tectons), can exhibit high permanent surface area and porosity. By choice of suitable tectons various functionalities can be introduced into such networks. Here we introduce chiral BINOL derivatives as novel tectons to generate microporosity in polymer networks. The use of such monomers enables the formation of networks composed solely out of enantiomerically pure compounds. This porous network can be used as a heterogeneous organocatalyst in asymmetric reactions and gives higher enantioselectivty than the homogeneous reaction.
