Stable zeolites with three-dimensional (3D) interconnected large-pore channels are crucial in industrial applications such as catalysis, adsorption, and separation.However, synthesizing these novel zeolites, especially high-silica forms, remains challenging.Here, guided by structural analysis, we designed an organic structure-directing agent (OSDA) enriched with cyclohexyl fragments to stabilize terminal bea CBUs, enabling the synthesis of a novel 2D large-
