Design and Synthesis of a Zeolitic Organic Framework**

The development of novel zeolite-like materials with large channel windows and high stability is importance but remains a tremendous challenge. Herein, we report the first example 3D covalent organic framework zeolitic network, namely (ZOF). By combining two kinds tetrahedral building blocks fixed or relatively free bond angles, ZOF-1 crb net has been successfully synthesized. Its structure was determined by single-crystal electron diffraction technique. Remarkably, shows chemical stability, pore size (up to 16 Å), excellent specific surface area (≈2785 m2 g−1), which superior its analogues same including traditional aluminosilicate zeolites imidazole frameworks. This study thus opens new avenue construct pure frameworks will promote their potential applications in adsorption catalysis for macromolecules.
