As new porous materials, metal organic frameworks (MOFs) and covalent organic frameworks (COFs) have been receiving an abundance of research interest in recent years. This book is the first comprehensive title to cover solid state NMR, 129Xe NMR and diffusion NMR methods that have been applied to solve the key scientific issues in the MOFs and COFs research like structural determination, examination of the local structures and host-guest interactions. Structural Information is crucial not only to understand the synthetic mechanisms but also to establish the structure-activity relationship of MOFs and COFs. In comparison to single-crystal X-ray diffraction and high-resolution electron microscopy, solid state NMR provides determinative or complementary information regarding MOFs and COFs. This book will benefit researchers who are interested in structural identification but have little expertise in NMR. It bridges a gap in knowledge and provides a unique reference work in this field of research.
