Molecular Magnetic Materials Based on Nanographenes: Controllable Synthesis and Characterization

Project description

Graphene-based molecular spintronics offers hope for quantum computing

Molecular spintronics is a new sub-area of spintronics that benefits from achievements in molecular electronics and molecular magnetism. It aims for the ultimate step towards the miniaturisation of spintronics by striving to actively control the spin states of individual molecules. Recent research demonstrated that nanographenes in very specific forms (with spin-bearing centres) have magnetic properties that could permit molecular spintronics applications. Controlling nanographenes' structure at the atomic level is the key to making them perform the desired functions. The EU-funded MolecularMAGNET project will employ a bottom-up synthetic approach to functionalise nanographenes and investigate how their size and configuration affects spin behaviour. The project will also reveal more clues about the intrinsic spin–injection mechanism in molecular magnetic materials based on nanographenes.

Objective

Molecular magnets based molecular spintronics, in which properties of bulk magnetic materials and molecular quantum effects coexist, have received a lot of attention, with potential applications in molecular spin detection and manipulation for information storage and the realization of spin qubits for quantum computing. But, the field has been struggling with limited candidates, and there is a constant searching for new materials. Recently, nanographenes, including graphene molecules (GMs) and graphene nanoribbons (GNRs) have displayed great potential in the application of electronics. The combination of nanographene with spin-bearing centers has been proved to be an effective way to construct novel molecular magnetic materials. However, to achieve reliable structure-property correlations and desired functions, control of the nanographene structure at the atomic level is required. This goal can be realized through bottom-up syntheses starting with rationally designed molecular precursors.
The primary objective of this project is using bottom-up synthetic approach to efficiently realize radical functionalized GMs and GNRs with defined structures, to systematically investigate the impact of their size and configuration on the behaviour of spin (multidisciplinary), and finally to reveal the intrinsic mechanism of spin-injection and interaction in molecular magnetic materials based on nanographenes (interdisciplinary).
This project will create an excellent opportunity for me to build upon my own expertise in bottom-up synthesis of graphene molecules possessing atomically precise structures with the Prof. Bogani group’s experience in the research of magnetic and electronic properties of nanocarbon materials.
