Texte intégralBinaphthyl-derived ligands containing P"=" O donor groups were employed for the rational synthesis of multi-properties coordination compounds with M〖(hfac)〗_3 units. The chiral bisphosphine oxide L acted as a chelate ligand giving monomeric racemic species of formula [〖{Ln(hfac)_3 L}〗_3] (Ln= Eu,Dy and Yb). These complexes were structurally characterized and their physical properties were studied in solid state. The compound [〖{Eu(hfac)_3 L}〗_3] exhibited metal-centred luminescence. Conversely, the ligand L was not able to sensitise luminescence emission for [〖{Dy(hfac)_3 L}〗_3]. However, the latter displayed field-induced SMM behaviour. The complex [〖{Yb(hfac)_3 L}〗_3] was an example of a chiral luminescent field-induced SMM. For both Dy(III)- and Yb(III)-based species, the magnetization relaxed via a similar Raman process under the effect of an external magnetic field. All these compounds sublimated when heated at reduced pressure. Subsequently, the coordination chemistry of the enantiopure binaphthyl-derived bisphosphate ligands (S)/(R)-L^n (n=1,3) and (S,S,S)/(R,R,R)-L^n (n=2,4) was studied. Reaction of these ligands with equimolar quantities of the metal precursors [M(hfac)_3 (H_2 O)_2] (M=Y,Eu,Dy and Yb) yielded enantiopure 1D-coordiantion polymers. With ligands (S)/(R)-L^n (n=1,3), two different polymorphic species could be crystallised by changing reaction conditions and nature of the metal ion. The Dy(III)-based compounds manifested field-induced SMM behaviour and luminescence emission. Magneto-optical correlation and results from ab initio calculations are presented. The complex 〖[Dy(hfac)_3 {(S)-L^1}]〗_n showed multiple contributions of the magnetization relaxation despite the presence of a single crystallographic Dy(III) centre. Solubilization of the coordination polymers 〖[M(hfac)_3 {(S)/(R)-L^1}]〗_n caused a structural reorganization to monomeric species of formula [M(hfac)_3 {(S)/(R)-L^1}]. This was demonstrated by NMR spectroscopy and DFT calculations. Similarly to the solid state, complex [Dy(hfac)_3 {(S)-L^1}] exhibited a multi-contribution field-induced SMM behaviour. The processes governing the magnetization relaxation of 〖[Dy(hfac)_3 {(S,S,S)-L^2}]〗_n and 〖[Dy〖(hfac)〗_3 {(S)-L^3 }]〗_n were further investigated by applying a strategy of magnetic dilution and isotopic enrichment with (_ ^163)Dy(III) (I=1⁄2) and (_ ^164)Dy(III) (I=0). Despite the minimisation of the dipolar interactions and the absence of nuclear spin, a strong field dependence of the magnetization was still observed. The ligands (S)/(R)-L^n (n=1,3) and (S,S,S)/(R,R,R)-L^n (n=2,4) efficiently sensitised the luminescence of the Eu(III)-based species. Their enantiopure nature promoted CPL emission in both solution and solid state. Finally, field-induced SMM behaviour and CPL emission were observed in the same compound by employing Yb(III) centres. The use of the functionalized TTF-based ligand L^5 and chiral Yb〖{(R)/(S)"-" facam}〗_3 units gave the enantiopure pair of dimers 〖[Yb〖{(R)/(S)"-" facam}〗_3 (L^5)]〗_2. The TTF fragment conferred redox activity. The application of a moderate static field revealed slow relaxation of the magnetization. Direct excitation of the ILCT states of L^5 sensitised the metal-centred luminescence. Moreover, both solution and solid state NIR-CPL emission were detected. The complex 〖[Yb〖{(R)/(S)"-" facam}〗_3 (L^5)]〗_2 was a redox chiral filed-induced SMM displaying CPL emission. Together with the Yb(III)-based complexes coordinated by the ligands (S)/(R)-L^n (n=1,3) and (S,S,S)/(R,R,R)-L^n (n=2,4), these are the first documented solid state NIR-CPL emissive examples for molecular complexes

Single molecule magnets (SMMs) are molecules of mesoscopic scale which exhibit quantum properties. Its quantum effects are used to describe the behavior of SMMs at the smallest scales. These quantum properties could also be used to reveal possible applications of SMMs to high-density information storage, molecular spintronics, and quantum information science. Thus SMMs are of interest to physicists, chemists, and engineers. Recently, electron transport via individual SMMs was achieved in experiments. Electron transport is obviously affected by the magnetic properties of the SMM, thus one can examine magnetic properties of an SMM indirectly by measuring electron transport via the SMM. In this thesis, two types of SMMs, Eu2(C8H8)3 and Ni9Te6(PEt3)8, are investigated theoretically by simulating their electron transport properties. An extended metal atom chain (EMAC) consists of a string of metallic atoms with organic ligands surrounding the string. EMACs are an important research field for nanoelectronics. Homometallic iron-based EMACs are especially attractive due to the high spin and large magnetic anisotropy of iron(II). If a molecule has magnetic anisotropy, its magnetic properties change with the direction of its magnetic moment. We explore how iron atoms interact with each other in the EMACs [Fe2(mes)2(dpa)2] and [Fe4(tpda)3Cl2]. Chapter 1 provides an introduction to SMMs, electron transport experiments via SMMs and an approximation method, density functional theory (DFT). DFT is a method to approximate electronic structure and magnetic properties of various many-body systems. Chapter 2 investigates theoretical electron transport via Eu2(C8H8)3. Eu2(C8H8)3 changes its type of magnetic anisotropy when it obtains an extra electron, which is different from most SMMs. If the Eu2(C8H8)3 is short of an extra electron, its magnetization direction is in-plane, that is, its magnetic energy is lowest when its magnetic moment is along any direction in a specific plane. If an extra electron is captured by Eu2(C8H8)3, its magnetization direction becomes out-of-plane, and its lowest energy is obtained when its magnetic moment is along the direction normal to the specific plane. The unique magnetic properties lead to blockade effects at low bias: the current through this molecule is completely suppressed until the bias voltage exceeds a certain value. The bias voltage on a molecule equals the electrical potential difference between two ends of the molecule. Chapter 3 investigates theoretical electron transport via Ni9Te6(PEt3)8. Magnetic anisotropy of Ni9Te6(PEt3)8 is cubic symmetric, and its symmetry is higher than most SMMs. With appropriate magnetic anisotropy parameters, in the presence of an external magnetic field, uncommon phenomena are observed. These phenomena include (1) current is completely suppressed when bias is low; (2) current via SMM decreases while bias on SMM increases; (3) there are discontinuous lines in the figures that describe electrical conductance of current. Chapter 4 examines the iron atoms’ interaction strength in both [Fe2(mes)2(dpa)2] and [Fe4(tpda)3Cl2]. Reasonable spin Hamiltonians are used to describe the energy of EMACs. Considering all possible directions of the spins of iron atoms in two EMACs, we calculate the energy of every possible spin configuration using DFT. The energy of each spin configuration can be expressed as an equation containing one or more coupling constants. We apply the least-squares fitting method to obtain the values of the coupling constants in the spin Hamiltonians.
