Накратко на български

Нови форми на въглерод, наречени циклокарбони, се синтезират и защитават с молекулярни пръстени (макроцикли), за да станат по-стабилни. Това помага за създаването на по-издръжливи материали за електрониката, съхранението на енергия и катализата.

Synthesis of new allotropes of carbon: Cyclocarbon catenanes

Generation of a new carbon allotrope is highly demanded, with respect to the impact of the other carbon allotropes, such as fullerene, graphene, and carbon nanotube. This project is designed to create new carbon allotropes that are stable for characterizations. The project of cyclic carbon allotrope protected by macrocycles aims to address the issue of emerging carbon materials, i.e., cyclocarbons, that are unstable and susceptible to chemical reactions and self-degradation, which will limit their practical applications. The use of macrocycles, which are cyclic molecules made up of multiple organic units forming cylindrical shapes, can protect carbon materials from environmental degradation, allowing them to maintain their unique properties and improve their stability. This project is important for society because carbon materials have numerous applications in fields such as electronics, energy storage, and catalysis. However, the instability of emerging carbon materials can limit their effectiveness and lifespan, which can hinder their widespread adoption and impact on society. By developing a more stable carbon allotrope protected by macrocycles, this project has the potential to improve the performance and longevity of carbon-based materials, leading to more efficient and sustainable technologies. The overall objectives of this project are to design and synthesize new carbon allotropes that are stabilized by macrocycles, characterize their properties, and explore their potential applications in various fields. Ultimately, the goal is to create carbon materials that can withstand harsh environments and maintain their unique properties, leading to more efficient and durable technologies.

Цел на проекта

The last 35 years have seen many advances in the field of new carbon allotropes, from fullerene chemistry to carbon nanotubes and graphene. Inspired by the huge impact of these new forms of carbon, we aim to create new carbon allotropes through the synthesis of cyclic molecules, cyclocarbons composed of only sp-hybridized carbon atoms, which are stabilized by the encapsulation of several macrocycles to form catenanes. The proposed project combines recent advances in polyyne chemistry (the field of the applicant's PhD) with supramolecular chemistry to create and study novel compounds: cyclocarbon catenanes. This project will include extensive synthetic work to find the most efficient working scheme for the formation of a stable cyclo[40]carbon catenane with suitable macrocycles. Dicobalt complexes will be incorporated into the polyyne precursors to form masked alkyne equivalents (MAEs). Active metal template (AMT) cross-coupling and/or homo-coupling reactions will be applied with MAEs to synthesize polyyne rotaxanes with suitable macrocycles on the polyyne thread. Cyclo-oligomerization using another AMT coupling, under high dilutions, is expected to yield a cyclo-tetramer, which can be unmasked to afford the target C40 catenane. The electronic nature of the target compounds will be studied using a range of techniques, including nuclear magnetic resonance spectroscopy, UV-vis absorption and fluorescence spectroscopy, electrochemistry, as well as time-resolved IR and Raman studies, additionally characterized with X-ray crystallography in the solid-state. These efforts will focus on exploring structure, reactivity, and physical properties of cyclocarbon molecules, to determine experimentally whether they are acetylenic or cumulenic in their ground states and excited states.
