A novel Q 3 →Q 4 transformation has been discovered in the structural transformation from a new interrupted zeolite PKU‐26 to a fully four‐connected zeolite framework PKU‐27 upon heating, which can improve the thermal stability of the framework by the condensation of the terminal ‐OH groups. A plausible mechanism of the structural transformation involving proton transfer, framework dehydration, and TO 4 reconstruction is proposed and supported by theoretical calculations. This may open the way for the design and structure optimization of zeolite frameworks. More information can be found in the Communication by S. Huang, J. Sun, Y. Wang, et al. on page 3219.
