Synthesis and Characterization of TMU-16-NH2 Metal-organic Framework Nanostructure Upon Silk Fiber: Study of Structure Effect on Morphine and Methyl Orange Adsorption Affinity

Thin films of a three-dimensional porous Zn(II)-based metal-organic framework, [Zn-2(H2N-BDC)(2)(4-bpdh)](center dot)3DMF (TMU-16-NR2), containing azine-functionalized pores, were deposited on surfaces of silk fiber via a stepwise manner. The effect of sequential dipping steps in growth of TMU-16-NH2 upon fiber has been studied. These systems depicted a decrease in the size accompanying a decrease in the sequential dipping steps. The deposition of TMU-16-NH2 upon silk fiber was monitored by XRPD and FT-IR. spectroscopy. The TMU-16-NH2 upon silk fiber can serve as a host for encapsulating morphine (Mph) and methyl orange (MO).
