Накратко на български
Химичните връзки и ароматността в наноклъстери от метали като желязо, кобалт и никел се анализират чрез теория и експерименти. Разбирането им помага за създаването на материали с по-добри оптични свойства и по-ефективни слънчеви панели.

Chemical bonding and aromaticity in novel inorganic and organometallic clusters
Clusters behave as a link between the atom and the bulk material. Their properties strongly depend on their size. Such nanoparticles can be potentially useful for many technical applications. The structural characterization of clusters is essential to understand the changes in their size-dependent properties. Experiments alone provide an incomplete picture of the cluster structure. In fact, a combination of theory and experiment is essential to get a complete description of these nanoparticles. Understanding the chemical bonding and aromaticity of these clusters is essential to fine tune their properties in the quest of new materials with enhanced non-linear optical properties, increased oxidant character, or improved charge transfer separation needed to construct more efficient solar cells. In the CANIOC project we have analyzed the chemical and aromaticity of supermolecular flowers, five-membered metallacycle rings, nanoclusters made of iron, cobalt and nickel in different proportions, and [M2N2]2- (M = B, Al, Ga), [M2N2]2+ (M = C, Si, Ge, Sn, Pb), E2P4 (E = B, Al, Ga, In), and CN3Be3+ and CO3Li3+ clusters. The CANIOC project has represented a great advance towards the design of novel clusters with fascinating properties.

Цел на проекта
Clusters behave as a link between the atom and the bulk material. They exhibit characteristics of both forms of matter, depending on their size and their molecular and electronic structures. Such molecules can be potentially useful for technical applications as specific and very efficient catalysts, drugs, and other novel materials with as yet unimagined properties. As an example, the continued miniaturization of electronic devices is pushing towards the nano- and molecular scales. In this sense, silicon clusters can be very important in the future development of the electronic industry. Other clusters are expected to have relevant catalytic or magnetic properties. All-metal and semi-metal clusters have been recently discovered. The unusual stability of all these clusters comes from their aromatic character. Indeed, the aromaticity is a key property of these compounds since it explains their stability and reactivity. As compared to the classical aromatic organic molecules, that possess only π-electron delocalization, the aromaticity in inorganic clusters is more complex. These compounds have σ- and π- (or even δ-) electron delocalization, thus giving rise to the so-called multifold aromaticity. All-metal and semimetal aromatic clusters represent one of the “new frontiers” of chemistry (the first of such clusters was discovered in 2001). It is expected that understanding the origin of aromaticity in these systems will help us to comprehend the factors that govern structural patterns and stability in solids. In addition, these novel materials are expected to have as-yet unimagined properties such as, for instance, nanodevices, intense non linear optical properties, high catalytic power and efficiency, and utility as possible drugs.
