Накратко на български
Хибридни наноматериали от въглерод и преходни метали, като молекули фулерен с уловени в тях атоми, се изследват за подреждане върху повърхности. Това помага за създаването на подходящи материали за квантовата обработка на информация и спинтрониката.

TRANSITION METALS IN CARBON NANOSTRUCTURES
Practical aspects of spintronics, and especially quantum information processing (QIP), are currently hindered because of the lack of suitable materials. The research project titled “Transition Metals in Carbon Nanostructures” has involved two different tasks, which are intended to solve existing problems producing a new class of hybrid metal-carbon nanomaterials with exploitable properties. The first task of this project has focused on the organization of electron-spin and optically active endohedral fullerene molecules X@Cn (where X is an atom or cluster incarcerated in the fullerene, and n is a number of carbon atoms in the fullerene cage) on surfaces and the investigation of functional properties of the obtained nanoscale architectures. In this case, the fullerene cage serves as “nano-container” which facilitates the incorporation of individual endohedral atoms with interesting optical and magnetic properties within supramolecular architectures. However, fullerene cages tend to have relatively isotropic exteriors owing to their spherical shapes, and so precise control of their positions and orientations can be difficult to achieve. An attractive approach for solving this problem is through chemical functionalisation of fullerene cages. This would allow for control over the orientation of the molecules via well-defined chemical bonding or highly directional non-covalent interactions. Thus, endohedral fullerenes functionalised with an appropriate chemical group could be able to form spontaneous molecular monolayers on surfaces. This strategy has been the main research vector for the formation of 2D arrays of these molecules at the nanoscale. There has been two central aims for the first task: i) Development of suitable methods for the controlled assembly of empty fullerenes on gold surfaces and ii) Transfer of the successful strategies utilised for empty fullerenes to magnetic and optically active endohedral fullerenes.

Цел на проекта
This is a research proposal of Dr Maria Gimenez for a Marie Curie Fellowship in the Carbon Nanomaterials group, University of Nottingham. Maria is a talented young inorganic chemist coming from a leading university in Spain, and who has a strong expertise in molecular magnetism, which will be invaluable for this research programme. During her stay in the Dr Khlobystov’s group she will learn unique experimental skills and methodology, which she will be able to transfer back to Spain. In this proposal transition metals chemistry will be applied for controlled assembly of fullerene dimers and magnetic quasi-1D chains inside carbon nanotubes, materials intended for nano-electronics and quantum information processing (QIP) applications. For example, individual endohedral fullerenes (such as N@C60) possess unique magnetic properties highly suitable for QIP applications. However, the assembly of multi-qubit systems by conventional methods of synthetic chemistry has proved to be extremely challenging. In this project we address this problem by applying the versatile and controllable chemistry of transition metals to fullerenes and nanotubes. The role of transition metals is twofold: (1) the metal centres are expected to provide efficient communication between electron spins in fullerene dimer architectures (two-qubit systems), and (2) the magnetic metal clusters are expected to serve as effective probes for the internal cavities of carbon nanotubes which can help to establish the mechanisms of the nanotube-electron spin interactions. The bonding of metal centres to carbon nanostructures is less disruptive than traditionally used covalent bonding. Therefore, transition metals are expected to have no detrimental effects on the intrinsic properties of fullerenes or nanotubes, but are anticipated to enhance the functional properties of these materials and to unlock their full potential for practical applications in electronic devices.
