A Zn-MOF with 8-fold interpenetrating structure constructed with N,N '-bis(4-carbozylbenzyl)-4-aminotoluene ligands, sensors and selective adsorption of dyes

摘要

A novel metal-organic framework {[Zn2L2(bibp)(2)]center dot H2O}(n) (L = N,N'-bis(4-carbozylbenzyl)-4-aminotoluene)(MOF 1) was synthesized and characterized, the structure presenting an 8-fold interpenetrating diamondoid networks with [4+4] mode, which exhibits high thermostability and two kinds of intertwined left- or right-handed double-helical chains. Additionally, the luminescence investigations reveal that 1 can sensitively detect Fe(III) ions in water. Furthermore, dye adsorption experiment results indicated that 1 can efficiently adsorb methyl orange(MO).
