This review deals with nanoporous materials made from the self-assembly of block copolymers with a special interest in the chemical functions covering the surface of their nanopores. A detailed overview of the existing methods and strategies to generate well-defi ned organic functional groups covering the surface of the pore walls is provided. This further enables to fi nely tune the affi nity of the pore walls and to perform well-defined chemical reactions onto them,which is essential for further dedicated applications
