Functionalized mesoporous metal-organic framework PCN-100: An efficient carrier for vitamin E storage and delivery

[Display omitted] •Mesoporous MOF, PCN-100, was functionalized to introduce various functionalities.•Modified PCN-100 showed remarkable performances for vitamin E storage/delivery.•The favorable interaction can be explained with hydrophobic, π–π and H–bonding.•The delivery rate could be controlled by changing pH of the solution for release. A mesoporous metal-organic-framework with amino group, PCN-100, was modified with terephthaloyl chloride (TC). The adsorption/delivery of vitamin E were carried out with pristine PCN-100, TC-modified PCN-100 (TC-PCN-100) and activated carbon (AC). The adsorbed quantity was in the order: AC
