Coordination Driven Capture of Nicotine Inside a Mesoporous MOF.

Metal organic frameworks (MOFs) are a wide class of crystalline porous polymers studied in many fields, ranging from catalysis to gas storage. In the past few years, MOFs have been studied for the encapsulation of organic or organometallic molecules and for the development of potential drug carriers. Here, we report on the study of two structurally-related mesoporous Cu-MOFs, namely PCN-6 and PCN-6′ (PCN stands for Porous Coordination Network), for nicotine trapping. Nicotine is a well-known alkaloid liquid molecule at room temperature, whose crystalline structure is still unknown. In this work, the loading process was monitored by electron ionization mass spectrometry by using a direct ins…

Mononuclear and polynuclear complexes ligated by an iminodiacetic acid derivative: synthesis, structure, solution studies and magnetic properties

Two novel families of coordination polymers, [Ln(bzlida)(Hbzlida)]·H2O (Ln = La, Nd) and [Ln2(bzlida)3]·3H2O (Ln = Nd, Sm, Eu, Gd) were prepared by hydrothermal reaction of Ln2O3 with benzyliminodiacetic acid (H2bzlida). The conditions of synthesis, in particular the pH value, were selected on the basis of previous speciation studies reported in this work. The first type of complex consists of 1D chains built by a fully deprotonated ligand bridging two lanthanide ions and protonated Hbzlida(-) ligands connecting three cations. The second type is formed by [Ln2(bzlida)3] bimetallic units in which the ligand has a tridentate NOO coordination mode. This is expanded to a 2D network through carb…
