Surface Functionalization of Porous Coordination Nanocages Via Click Chemistry and Their Application in Drug Delivery

Authors


Abstract

original image

Porous coordination nanocages covered with alkyne groups are synthesized through judicious selection of the ligand and reaction conditions. The surface functionalization via click reaction with azide-terminated polyethylene glycol turns them into water-stable colloids, which exhibit controlled release of an anticancer drug 5-fluorouracil.
