Texte intégralNowadays, going from molecules to devices is one of the main challenge in the field of switchable molecular materials. In this context, spin crossover complexes (SCO) are good candidates as they can be reversibly switched from a low spin state to a high spin state with various external stimuli (temperature, light ...). This switch is followed by an important change of their physical properties (magnetic, optical, elastic...). The objective of this Ph.D thesis is to synthetize and characterize films and nanocomposites based on spin crossover materials for applications in electronical and mechanical and optical devices. A first approach to obtain thin film that can be integrated consist in using sublimation technique. To this aim, neutral Fe(II) complexes based on poly(azolyl)borate ligand have been synthetized. Studies of the correlation between spin crossover properties and structural properties have been complemented with synchrotron measurements to determine crystal lattice dynamics parameters. Films of these complexes have been integrated in electrical junction bringing new bistability properties and displaying different conduction mechanisms depending on the SCO film thickness. Films have been also deposited on micro-electromechanical systems (MEMS) which demonstrated mechanical bistability. Another approach reside in elaborating composite materials based on polymer and SCO complexes. Thus, a cellulose composite paper based on SCO complexes has been prepared and studied by dynamic mechanical analysis indicating a bistability of its mechanical properties. A proof of concept of a re-writable composite paper using SCO thermochromism has been presented. In another hand, nanocomposites based on the electroactive polymer P(VDF-trFE) (piezo-, pyro- and ferroelectric), and SCO nanoparticles has been synthetized. A study of their electromechanical properties revealed current discharge peaks associated to the SCO phenomenon highlighting a synergy between the two composites constituents

Texte intégralThe continual quest for ever-smaller technological components has led to massive research efforts in the fields of molecular electronics and, more recently, spintronics. These components should be simultaneously more powerful and less energy-hungry, and in this context, spin crossover (SCO) molecules have far-reaching potential. These transition metal complexes can be switched between two distinct states by a multitude of stimuli, and exhibit substantial changes in their chemical and physical properties upon switching, giving them many prospective applications.This thesis presents several new iron (II) SCO molecules with a thermal - and in some cases photo-induced - switching that is dependent on the degree of steric hindrance of the ligands. Typically, SCO in monolayers is significantly altered due to molecule-substrate interactions, but the molecules presented in this thesis exhibit a rarely observed non-quenched SCO thanks to an alkyl spacer separating the SCO moiety from the coinage metal substrates. The SCO of the molecules in bulk was followed by magnetometry (vibrating sample magnetometry, VSM, and superconducting quantum interference device, or SQUID, magnetometry), variable-temperature nuclear magnetic resonance (NMR) and Raman spectroscopies, as well as X-ray photoelectron and absorption spectroscopies (XPS and XAS, respectively). The SCO behaviour of the monolayers was characterised by XPS and XAS.Thanks to a flexible synthesis route, these novel molecules can form both self-assembled monolayers (SAMs) and break junctions, depending on the number and nature of the anchoring groups. SAMs have been prepared on ultra-flat gold, silver and copper substrates. The morphology, chemical composition, and packing of these monolayers were characterised by atomic force microscopy (AFM), time-of-flight secondary ion mass spectrometry (ToF-SIMS), XPS semi-quantitative analysis, polarisation modulation infrared reflection absorption spectroscopy (PM-IRRAS), and electrochemistry, supported by density functional theory (DFT) calculations.In order to turn these SAMs into switchable devices, eutectic Gallium Indium (eGaIn) was used as a top electrode. This alloy is a soft and deformable non-Newtonian fluid capable of forming non-damaging contacts with molecules. The electrical properties of large-area molecular junctions were thus measured, initially at room temperature, and then above and below, in order to follow the changes in transport behaviour with temperature. Single molecule junctions were formed using two different methods, both at room temperature: scanning tunnelling microscopy (STM) in solution, and single-walled carbon nanotube nanogap junctions in the solid state. Though the changes in electronic behaviour of the SAMs with temperature could not be conclusively assigned to SCO, this thesis shows that, with some fine-tuning, these systems are feasible as switchable components.The easily tuneable synthesis route gives this family of molecules countless potential applications, and opens up numerous different avenues for future research. The presented molecular junction systems help pave the way towards stable, low-power, multi-addressable, and switchable molecular devices that function at ambient conditions

Hidrintos dangos ištirtos įvairiais analizės metodais, siekiant nustatyti magnetronio garinimo būdu suformuotos medžiagos (magnio nikelio hidrido) skirtumus nuo rutulinio trynimo metodu gautos analogiškos medžiagos. Darbe išanalizuoti duomenys ir pateiktas aiškinamasis modelis, kuris atskleidžia plonų dangų ypatybes, dėl kurių dangose pilnai neįvyksta dangos relaksacijos procesai. Nustatyta, kad dėl tų pačių priežasčių, dangų panaudojimo „įjungiamiesiems veidrodžiams“ galimybės yra ribotos.
