Research Progress in Covalent Organic Frameworks for Photoluminescent Materials

Covalent organic frameworks (COFs) are an emerging kind of crystalline porous polymers that present the precise integration of organic building blocks into extensible structures with regular pores and periodic skeletons. The diversity of organic units and covalent linkages makes COFs a rising materials platform for the design of structure and functionality. Herein, recent research progress in developing COFs for photoluminescent materials is summarised. Structural and functional design strategies are highlighted and fundamental problems that need to be solved are identified, in conjunction with potential applications from perspectives of photoluminescent materials. Polymer skeletons: In this review, recent research progress in developing covalent organic frameworks for photoluminescent materials is summarised. The fundamental problems that need to be solved, in conjunction with potential applications from the perspective of photoluminescent materials, are also discussed.
