The development of inorganic frameworks with extra‐large pores (larger than 12‐membered rings) has attracted considerable attention because of their potential applications in catalysis, the separation of large molecules, and so forth. We herein report the synthesis of the new extra‐large‐pore zeolite NUD‐2 by using the supramolecular self‐assembly of simple aromatic organic cations as structure‐directing agents (SDAs). NUD‐2 is a high‐silicon‐content germanosilicate with interconnecting 14×10‐membered‐ring channels. The SDAs in NUD‐2 can be removed by calcination in air at 550 °C to yield permanent pores with a BET surface area of 500 m2g−1. Both germanium and organic cations in NUD‐2 can also be removed by treatment with acid at lower temperature, thus not only affording recycling of germanium and SDAs, but also providing a highly stable siliceous zeolite. In addition, aluminum ions can be incorporated into the framework of NUD‐2. The NUD‐2 structure is yet another extra‐large‐pore zeolite synthesized by using the supramolecular self‐assembling templating approach, thus demonstrating that this approach is a general and applicable strategy for synthesis of new large‐ and extra‐large‐pore zeolites.
