Magnetic functionalities in MOFs: from the framework to the pore

Abstract

In this review, we show the different approaches developed so far to prepare metal-organic frameworks (MOFs) presenting electronic functionalities, with particular attention to magnetic properties. We will cover the chemical design of frameworks necessary for the incorporation of different magnetic phenomena, as well as the encapsulation of functional species in their pores leading to hybrid multifunctional MOFs combining an extended lattice with a molecular lattice.

Construction of Large‐Area Ultrathin Conductive Metal–Organic Framework Films through Vapor‐Induced Conversion

“…In numerous studies, magnetic inorganic subunits (metal centers, clusters, chains …) could endow MOFs with magnetism, but most are insulators. Figure f,g exhibited that the 40 nm film owned an obvious magnetization hysteresis and the coercive force decreased with the increase of temperature, being ascribed to Ni 2+ . The similar phenomena could also be found in 7 and 92 nm films (Figure S12, Supporting Information).…”

A Robust Framework Based on Polymeric Octamolybdate Anions and Copper(II) Complexes of Tetradentate N-donor Ligands

“…These hybrid layers parallel to the xz plane are further connected through Cu2 complexes along the [10] direction, in such way that each polymeric anion results linked to the four neighboring chains. Two different grafting sites can be identified for the two complexes: inner (for Cu1) and bridging (for Cu2) {MoO 6 } moieties between Mo 8 O 26 subunits (Figure 3).…”

“…Particularly, the former field has entered a new stage where not only the porosity but also other physical properties are playing a key role in their potential application in current fields of interest like catalysis, magnetism or biomedicine [6][7][8][9][10]. However, this often requires the activation of the functional material through evacuation of solvent molecules.…”

Synthesis, Thermal Stability, and Magnetic Properties of a Manganese(II) Coordination Framework Containing Bistriazolate Ligands

“…Another triazolate ligand, benzotriazole-5-carboxylic acid (4), was reported to be very useful in preparing Mn(II) MOFs, especially those with interesting magnetic properties. [16][17][18][19][20] With regard to that, a magnetic exchange between paramagnetic metal centers is important and is primary dependent on the nature of the bridging ligand.
