✦ Synopsis

Zeolites have been widely used, among others, as catalysts, ion exchangers, detergents, and adsorbents, and their range of applications continues to grow. Thus, there is a large demand for new types of zeolites with high thermal and chemical stability. However, new zeolites are still mainly synthesized by trial and error, and molecular engineering in their synthesis has been underdeveloped. Here we report that a thermostable zeolite with a novel framework is obtained by molecular manipulation, that is, topotactic dehydration-
