An intermetallic molecular nanomagnet with the lanthanide coordinated only by transition metals.

ABSTRACT: Magnetic molecules known as molecular nanomagnets (MNMs) may be the key to ultra-high density data storage. Thus, novel strategies on how to design MNMs are desirable. Here, inspired by the hexagonal structure of the hardest intermetallic magnet SmCo₅, we have synthesized a nanomagnetic molecule where the central lanthanide (Ln) Er^III is coordinated solely by three transition metal ions (TM) in a perfectly trigonal planar fashion. This intermetallic molecule [Er^III(Re^ICp₂)₃] (ErRe₃) starts a family of molecular nanomagnets (MNM) with unsupported Ln-TM bonds and paves the way towards molecular intermetallics with strong direct magnetic exchange interactions-a promising route towards high-performance single-molecule magnets.

On-surface preparation of coordinated lanthanide-transition-metal clusters.

Project description:The study of lanthanide (Ln)-transition-metal (TM) heterometallic clusters which play key roles in various high-tech applications is a rapid growing field of research. Despite the achievement of numerous Ln-TM cluster compounds comprising one Ln atom, the synthesis of Ln-TM clusters containing multiple Ln atoms remains challenging. Here, we present the preparation and self-assembly of a series of Au-bridged heterometallic clusters containing multiple cerium (Ce) atoms via on-surface coordination. By employing different pyridine and nitrile ligands, the ordered coordination assemblies of clusters containing 2, 3 and 4 Ce atoms bridged by Au adatoms are achieved on Au(111) and Au(100), as revealed by scanning tunneling microscopy. Density functional theory calculations uncover the indispensable role of the bridging Au adatoms in constructing the multi-Ce-containing clusters by connecting the Ce atoms via unsupported Ce-Au bonds. These findings demonstrate on-surface coordination as an efficient strategy for preparation and organization of the multi-Ln-containing heterometallic clusters.

Allylic Hydrogen Acidity of 1-Butene Derivatives Coordinated to Transition Metals─A Mechanistic Insight Including Carbonyl-Olefin Metathesis.

Project description:The coordination of organic molecules to transition metals significantly alters the electron density distribution, influencing the acidity of specific hydrogen atoms. This study scrutinizes the acidity of allylic hydrogens in transition metal-coordinated alkenes, delving into the factors that govern allylic proton abstraction. Employing density functional theory, we investigate the effects of various parameters, including the electronic nature of substituents on the vinylic carbons of the alkene, the oxidation state of the metal, and the identity of the transition metal center on the allylic hydrogens' acidity. Our findings reveal that the impact on the acidity of allylic hydrogens in alkenes coordinated to gold(III), a third-row transition metal, is considerably substantial both kinetically and thermodynamically. Conversely, the impact is minimal for cobalt(III) from the first row and moderate for rhodium(III) from the second row of transition metals. Furthermore, our results indicate that electron-withdrawing substituents on vinylic carbons generally enhance the acidity of allylic hydrogens. The influence of oxidation state is also profound, as gold(I) exhibits markedly weaker effects compared to gold(III). To illustrate the practical application of these insights, we present a case study involving the use of AuCl3 to catalyze an organic transformation [Chem. Eur. J. 2020, 26, 1941-1946], elucidating the mechanism initiated by the deprotonation of the allylic hydrogen in the coordinated alkene.

Quantum signatures of a molecular nanomagnet in direct magnetocaloric measurements.

Project description:Geometric spin frustration in low-dimensional materials, such as the two-dimensional kagome or triangular antiferromagnetic nets, can significantly enhance the change of the magnetic entropy and adiabatic temperature following a change in the applied magnetic field, that is, the magnetocaloric effect. In principle, an equivalent outcome should also be observable in certain high-symmetry zero-dimensional, that is, molecular, structures with frustrated topologies. Here we report experimental realization of this in a heptametallic gadolinium molecule. Adiabatic demagnetization experiments reach ~200 mK, the first sub-Kelvin cooling with any molecular nanomagnet, and reveal isentropes (the constant entropy paths followed in the temperature-field plane) with a rich structure. The latter is shown to be a direct manifestation of the trigonal antiferromagnetic net structure, allowing study of frustration-enhanced magnetocaloric effects in a finite system.

Chemical tunnel-splitting-engineering in a dysprosium-based molecular nanomagnet.

Project description:Total control over the electronic spin relaxation in molecular nanomagnets is the ultimate goal in the design of new molecules with evermore realizable applications in spin-based devices. For single-ion lanthanide systems, with strong spin-orbit coupling, the potential applications are linked to the energetic structure of the crystal field levels and quantum tunneling within the ground state. Structural engineering of the timescale of these tunneling events via appropriate design of crystal fields represents a fundamental challenge for the synthetic chemist, since tunnel splittings are expected to be suppressed by crystal field environments with sufficiently high-order symmetry. Here, we report the long missing study of the effect of a non-linear (C4) to pseudo-linear (D4d) change in crystal field symmetry in an otherwise chemically unaltered dysprosium complex. From a purely experimental study of crystal field levels and electronic spin dynamics at milliKelvin temperatures, we demonstrate the ensuing threefold reduction of the tunnel splitting.

Lanthanide-Coordinated Semiconducting Polymer Dots Used for Flow Cytometry and Mass Cytometry.

Project description:Simultaneous monitoring of biomarkers as well as single-cell analyses based on flow cytometry and mass cytometry are important for investigations of disease mechanisms, drug discovery, and signaling-network studies. Flow cytometry and mass cytometry are complementary to each other; however, probes that can satisfy all the requirements for these two advanced technologies are limited. In this study, we report a probe of lanthanide-coordinated semiconducting polymer dots (Pdots), which possess fluorescence and mass signals. We demonstrated the usage of this dual-functionality probe for both flow cytometry and mass cytometry in a mimetic cell mixture and human peripheral blood mononuclear cells as model systems. The probes not only offer high fluorescence signal for use in flow cytometry, but also show better performance in mass cytometry than the commercially available counterparts.

Synthesis and Reactivity of Bis(silylene)-Coordinated Calcium and Divalent Lanthanide Complexes.

Project description:Divalent lanthanide complexes of Eu (1) and Yb (2) coordinated by a chelating pyridine-based bis(silylene) ligand were isolated and fully characterized. Compared to the EuII complex 1, the YbII complex 2 presents a lower thermal stability, resulting in the activation of one SiII -N bond and formation of an YbIII complex (3), which features a unique silylene-pyridyl-amido ligand. The different thermal stability of 1 and 2 points towards reduction-induced cleavage of one SiII -N bond of the bis(silylene) ligand. Successful isolation of the corresponding redox-inert bis(silylene) CaII complex (5) was achieved at low temperature and thermal decomposition into a CaII complex (4) bearing the same silylene-pyridyl-amido ligand was identified. In this case, the thermolysis reaction proceeds through another, non-redox induced, mechanism. An alternative higher yielding route to 4 was developed through an in situ generated silylene-pyridyl-amine proligand.

A thermophysical investigation of weakly coordinated metals in ionic liquids.

Project description:Ionic liquids can solvate metals without strongly coordinating them, which gives a rare opportunity to probe the complexity of weakly coordinated metals through characterisation of liquid properties. In this work we use bis(trifluoromethanesulfonyl)imide (i.e. bistriflimide; [NTf2]-) anions to prepare weakly coordinated metal containing ionic liquids (MILs) that are highly versatile because they are reactive with readily substituted ligands. Weakly coordinated metals are more than highly active catalysts. They are primed to create dynamic systems that are useful in other areas such as battery electrolytes, soft materials, and separations. However, very little is known about the properties of ionic liquids with weakly coordinated metals, so we present a wide scope analysis of nineteen 1-alkyl-3-methylimidazolium bistriflimide ILs with five different M[NTf2] n salts (M = Li, Mg, Zn, Co, Ni) in variable concentration to understand how metal cations influence thermophysical properties. We investigate short- and long-term thermal stability, decomposition kinetics, and decomposition mechanisms which provides operating windows and knowledge on how to improve stability. In particular, we find that all metals catalyse the elimination decomposition process, which severely compromises thermal stability. Alongside this, we present a detailed analysis of viscosities, densities, and heat capacities, the latter of which revealed that bistriflimide metal ILs are prone to drawing water from the air to form strong hydration spheres. Thermal parameters are affected to varying degrees, but desorption is possible under elevated temperatures - further justifying the need to know upper temperature limits. Altogether, this work provides a broad and methodical study to help understand solvent-solute interactions and thus design better systems for emerging applications that utilise weakly coordinated metals.

Multi-principal elemental intermetallic nanoparticles synthesized via a disorder-to-order transition.

Project description:Nanoscale multi-principal element intermetallics (MPEIs) may provide a broad and tunable compositional space of active, high-surface area materials with potential applications such as catalysis and magnetics. However, MPEI nanoparticles are challenging to fabricate because of the tendency of the particles to grow/agglomerate or phase-separated during annealing. Here, we demonstrate a disorder-to-order phase transition approach that enables the synthesis of ultrasmall (4 to 5 nm) and stable MPEI nanoparticles (up to eight elements). We apply just 5 min of Joule heating to promote the phase transition of the nanoparticles into L10 intermetallic structure, which is then preserved by rapidly cooling. This disorder-to-order transition results in phase-stable nanoscale MPEIs with compositions (e.g., PtPdAuFeCoNiCuSn), which have not been previously attained by traditional synthetic methods. This synthesis strategy offers a new paradigm for developing previously unexplored MPEI nanoparticles by accessing a nanoscale-size regime and novel compositions with potentially broad applications.

A hard molecular nanomagnet from confined paramagnetic 3d-4f spins inside a fullerene cage.

Project description:Reducing inter-spin distance can enhance magnetic interactions and allow for the realization of outstanding magnetic properties. However, achieving reduced distances is technically challenging. Here, we construct a 3d-4f metal cluster (Dy2VN) inside a C80 cage, affording a heretofore unseen metallofullerene containing both paramagnetic 3d and 4f metal ions. The significantly suppressed 3d-4f (Dy-V) distances, due to the unique cage confinement effect, were observed by crystallographic and theoretical analysis of Dy2VN@Ih(7)-C80. These reduced distances result in an enhanced magnetic coupling (Jtotal, Dy-V = 53.30 cm-1; Jtotal, Dy-Dy = -6.25 cm-1), leading to a high magnetic blocking temperature compared to reported 3d-4f single-molecule magnets and strong coercive field of 2.73 Tesla. Our work presents a new class of single-molecule magnets with both paramagnetic 3d and 4f metals confined in a fullerene cage, offering superior and tunable magnetic properties due to the unique cage confinement effect and the diverse composition of the entrapped magnetic core.
