NMR spectra of MIL-100(Al), CD-CO@nanoMIL-100(Al), CD-13CO@nanoMIL-100(Al), and DOX loaded CD-13CO@nanoMIL-100(Al). (A). 13C CPMAS NMR spectra of (a) MIL-100(Al), (b) CD-CO@nanoMIL-100(Al), (c) CD-13CO@nanoMIL-100(Al), and (d) DOX loaded CD-13CO@nanoMIL-100(Al). In (d), the small unlabeled peaks correspond to the DOX molecules. The intense 13C resonances is truncated for sake of clarity. In (c), 1 and 2 show the two labeled carboxylic resonances. Line 2 corresponds to the 13C carboxylic atoms of the CO linked to the surface aluminum sites of the MOF. Line 1 is a superimposition of COOAl carboxylic of the trimesate BTC linker and the 13COO-CD of the polymer coating. (B). 1H-1H 2D MAS NMR spectrum of DOX loaded CD-13CO@nanoMIL-100(Al) dried. (C). 2D 13C-27Al D-HMQC 2D of (a) nanoMIL-100(Al), (b) CD-13CO@nanoMIL-100(Al) and (c) DOX loaded CD-13CO@nanoMIL-100(Al).
