Frontispiece: Research Progress in Covalent Organic Frameworks for Photoluminescent Materials

Luminescent covalent organic frameworks (COFs), with a high surface area, tuneable structural designs and excellent physicochemical stability, are a new class of photoluminescent materials. Abundant synthetic methods and the availability of organic building blocks allow the design and preparation of crystalline porous frameworks, while engineering the functionality. Recent research progress in developing COFs for photoluminescent materials is summarised in the Review on page 16568., by Xian‐Zheng Zhang et al.
