Drug delivery and selective CO2 adsorption of a bio-based porous zinc-organic framework from 2,5-furandicarboxylate ligand

Drug delivery and selective CO2 adsorption of a bio-based porous zinc-organic framework from 2,5-furandicarboxylate ligand
A hydrostable and biofriendly porous Zn-based MOF with chemical formulae {[Zn(FDC)]·H2O}n (1) (FDC=2,5-furandicarboxylate) was synthesized and structurally characterized. TGA, PXRD, and water vapor sorption results show high thermal and water stability for the framework. 1 exhibits a 3D framework and shows a (4,8)-connected structure of a rare scu topology with the channels of 7.0×7.8 and 6.3×8.5Å2 along the a and b axis, respectively. Desolvated 1 shows not only high 5-fluorouracil payloads (adsorbs around 22.5wt%) but also very high CO2 selective capture compare with other small gases (i.e. CH4, N2, O2, CO and H2) at 298K. The in vivo Zebrafish toxicity tests and in vitro MTT assays of 1 at different concentrations results reveal that 1 is nontoxic.
