Covalent organic frameworks(COFs)with hierarchical porosity have drawn considerable attention very recently due to their advantages over the COFs with uniform porosity in some aspects.However,the design strategies for the construction of this type of COFs,namely heteropore COFs,are quite limited.We herein report a facile approach to constructing a two-dimensional COF which possesses three dif-ferent kinds of pores.Its structure is confirmed by powder X-ray diffraction and nitrogen sorption studies.The successful construction of the triple-pore COF represents a new method to access COFs with high hierarchical porosity.
