Scheme 1. (a) Reaction sequence for the synthesis of
UiO-66(Zr)-NH2 and trimesoyl chloride
(TMC)-functionalized UiO-66(Zr)-NH2 nanoparticles. (b)
Schematic diagram for the fabrication ofthin-film nanocomposite
(TFN) membranes via the covalent bonding between metal–organic
frameworks (MOFs) and TMC (UiO-66(Zr)-NH2 was used as an
example of MOF). Here 2-NH2-BDC, DMF, PAN, HPAN, DETA,
and IP denote 2-aminoterephthalic acid, N,N-dimethylformamide,
polyacrylonitrile, hydrolyzed polyacrylonitrile, diethylenetriamine, and
interfacial polymerization, respectively.
