Crystal growth of thin [Zn2(H2N-BDC)2(4-bpdb)] · 3DMF metal–organic framework nanostructure on functionalized surfaces: study of structure effect on methyldopa adsorption affinity

Abstract

Thin films of a three-dimensional porous Zn(II)-based metal–organic framework, [Zn₂(NH₂-BDC)₂(4-bpdb)] · 3DMF (TMU-17-NH₂), 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-17-NH₂ has been studied. These systems depicted a decrease in the size accompanying a decrease in the sequential dipping steps. The TMU-17-NH₂ has been used as matrices for the adsorption and in vitro guest delivery of methyldopa (MD).
