Накратко на български
Хибридни въглеродни структури, като комбинации от фулерени, графен и въглеродни нанотръби, се създават чрез добавяне на специални групи за промяна на разтворимостта им. Това помага за по-лесното им използване в технологични приложения като органични слънчеви клетки и биоматериали.

New hybrid-nanocarbon allotropes based on soluble fullerene derivatives in combination with carbon nanotubes and graphene. Application in organic solar cells and biomaterials.
The aim of Hy-solFullGraph was to develop synthetic methodologies to yield new functional hybrid carbon allotropes with tuned solubility and to demonstrate their versatility for various technological applications. The overall objectives were: 1-Tailoring the solubility of fullerenes and graphene by functionalisation with substituents of different natures (hydrophobic, hydrophilic, and polyfluorinated) 2-Selective functionalisation of fullerenes with appropiate reactive groups so that they can be used as nano-building-blocks for the assembly of hybrid SCAs nanostructures 3-Characterisation in terms of structure and functionality Objectives 4 and 5 were related to their application, howbeit solubility problems together with the lack of activity caused a redirection of the project. We have explored the selective functionalisation of different SCAs including fullerene, carbon nanotubes (CNTs), carbon nano-onions (CNOs) and graphene towards the synthesis of novel molecular hybrid architectures. New soluble fullerene building blocks ranging from superhydrophobic to hydrophilic have been synthesised and used as solubilising vectors to induce their solubility behaviour to other materials and to improve the processability. The solubility of nanocarbons is of paramount importance for their practical application, therefore this project has tackled an important issue to boost their use. Hybrid-SCAs are currently a challenging area of research still at its infancy. Many interesting properties are envisioned for the hybrid combination of allotropes. For this porpouse, fullerenes with tailored solubility have been covalently attached to endohedral fullerene Sc3N@ C80 to induce a better solubility; the electronic interactions between the hybrid-SCAs are being studied. This is the first example of a dumbbell molecule combining and empty C60 fullerene with a cluster metallic one. Furthermore, other interesting Hybrids like graphene-C60 and CNT-C60 have been investigated. This project has given important insights into functionalised fullerene properties helping to guide the design of new hybrid- materials with desirable properties like tunable solubility, which are in high demand for technological applications. Also this project shed light on the reductive functionalisation of multilayered fullerenes which is of great interest for the basic understanding of the role of defects and curvature on their reactivity.

Цел на проекта
The overarching goal of the Hy-solFullGraph project is to undertake, from a molecular level, the synthesis of new functional hybrid materials based on carbon allotropes with outstanding properties. Synthetic carbon allotropes (SCAs) are regarded to be among the most promising candidates for future high performance materials. Precise control of the derivatisation will play a key role in tailoring their solubility and reactivity to maximise the advantages of their outstanding properties. We propose herein 1) to selectively functionalise C60 fullerenes with different substituents (hydrophobic, hydrophilic, and polyfluorinated) to tune their solubility and their superstructured assembly. 2) By controlling the addition pattern, we will include an additional functional group which will facilitate their covalent attachment to other carbon allotropes such as graphene or CNT. In this way, new Hybrid-SCAs will be synthesised for the very first time and the interactions between the hybrid allotropes will be unravelled. 3) Moreover, by changing the chemical decoration around the allotropes, we will be able to endow them with different functionality for their application in optoelectronic and biomedical fields. For optoelectronic applications, such as the development of solar cells, we propose to tune the electronic interactions and energy levels of fullerene and graphene and to control the energy transfer processes and packing behaviours between the allotropes by well-designed chemical functionalisation. Furthermore, we will use the hydrophilic fullerenes to prepare functional biomaterials by taking advantage of their electrical properties to ultimately assist nerve tissue regeneration. The project will be developed at the crossroads of organic and supramolecular chemistry, materials science, nanotechnology and physical chemistry to produce novel synthetic hybrid carbon allotropes with tailored properties towards new nanomaterials for optolectronical and biomedical applications
