shape-selective catalysts. The successful synthesis of 3D porous functionalized
COFs would greatly facilitate the development of COFs as promising selective
catalysts.
Owing to the various advantages of POF materials, including diversiform
porous structures, high stability, and adjustable skeletons, POFs display excellent
