Abstract
Triptycene-based porous organic frameworks (POFs) with high BET (Brunauer–Emmett–Teller) surface areas and tailored micropore environments were prepared using a facile external knitting strategy. The functionalized POFs exhibited very high aliphatic amine vapor uptakes of up to 5 times their own weight and more than 30 times selectivity for aliphatic amines over n-hexane; thus, they provide new opportunities for environment-related applications.
