“…To increase the efficiency of FM extraction from CCs, a mechanical extraction (ME) method was developed. , The ME method was used to extract both a FM enriched with higher fullerenes and EMF. The latter content for the case of EMF with Y was 25 wt %.…”

In the present work, the polymerization of endohedral metallofullerenes (EMFs) with gadolinium (Gd@C 82 ) and yttrium atoms (Y@C 82 ) at high pressures achieved using the shear diamond anvil cell technique is studied using both theoretical and experimental approaches. It is found that in contrast to pure fullerenes, EMF polymerization starts at lower pressures with similar behavior for both metals inside the fullerene cage. EMF polymerization occurs smoothly and finally leads to a significant increase in the number of interfullerene bonds at pressures higher than ∼20 GPa. Finally, a high bulk modulus of both EMFpolymerized materials is obtained using Raman spectra.

“…The combination of the mechanical influence with the filtration led to a massive reduction in the time taken for extraction (~15 min) compared to the traditional Soxhlet extraction method, whilst maintaining a similar resultant weight percentage of fullerene-to-soot-extraction ratio. The same group went on to demonstrate the efficiency of the method with higher cage empty fullerenes and EMFs [131]. They showed that the mechanical extraction method could extract 0.4 wt% higher weight fullerenes, which consisted of about 25% EMFs.…”

Fullerenes have a unique structure, capable of both encapsulating other molecules and reacting with those on the exterior surface. Fullerene derivatives have also been found to have enormous potential to address the challenges of the renewable energy sector and current environmental issues, such as in the production of n-type materials in bulk heterojunction solar cells, as antimicrobial agents, in photocatalytic water treatment processes, and in sensor technologies. Endohedral metallofullerenes, in particular, can possess unpaired electron spins, driven by the enclosed metal atom or cluster, which yield valuable magnetic properties. These properties have significant potential for applications in molecular magnets, spin probes, quantum computing, and devices such as quantum information processing,, atomic clocks, and molecular magnets. However, the intrinsically low yield of endohedral fullerenes remains a huge obstacle, impeding not only their industrial utilization but also the synthesis and characterization essential for exploring novel applications. The low yield and difficulty in separation of different types of endohedral fullerenes results in the usage of a large amount of solvents and energy, which is detrimental to the environment. In this paper, we analyse the methodologies proposed by various researchers and identify the critical synthesis parameters that play a role in increasing the yields of fullerenes.
