Researcher | Scientific reviewer

Diana Visinescu is a Senior Researcher 1 working at the Coordination and Supramolecular Chemistry Laboratory, Institute of Physical Chemistry- Ilie Murgulescu, Romanian Academy. She received her PhD from the University of Bucharest (2003, Acad. Marius Andruh), followed by three postdoctoral stages in France, at the ICMCB-CNRS / University of Bordeaux, Dr. Jean-Pascal Sutter) and in Spain, at the ICMol/University of Valencia, 2006-2008, Prof. Miguel Julve). In 2011, she was awarded by the Romanian Academy with “Gheorghe Spacu” Prize. Her research interests focus on coordination chemistry: design/synthesis of molecular magnetic materials, crystal engineering and magnetochemistry of heterometallic complexes. She is also interested in the chemistry of (nano)materials relevant for electrochemical applications: metal oxides (MO), carbonaceous materials (C), MO/C composites, eco-friendly synthesis of micro-/nanoparticles of MO or MO/C.

Abstract:

The heterometallic complexes of various dimensionalities and topologies are very appealing for molecular magnetism. The main objective of the proposed project is the design and synthesis of new low dimensional magnetic heteropolymetallic molecular materials (from 0-D to 2-D). Using a bottom-up, rational approach, by assembling heteroleptic cyanido metalloligands with mono or bimetallic molecular bricks, heterometallic coordination polymers are synthesized. Molecular nanomagnets (Single-molecule magnets, SMMs and Single-chain magnets, SCMs) and ferrimagnetic chains with SCM behaviour are particularly envisaged. Moreover, the ferrimagnetic chains, ferromagnetically interacting through hydrogen bonds, can exhibit 3-D (supra)molecular magnet properties. A special attention will be devoted to multifunctional molecular materials, by combining magnetic properties with optical properties, chirality or luminescence. The project has an interdisciplinary character and will be a collaborative effort involving PhD students, postdoctoral and experienced researchers.

Abstract:

The present project has as general scientific objective the developing of innovative green strategies polysaccharides-assisted for the design/synthesis of tailor made oxide-based nanomaterials, exploiting polysaccharides diverse and versatile properties (water-solubility, polyfunctionality, hydrophilicity, chemical reactivity, chirality, chelation/coordination, gelling, assembling and adsorption abilities). Precipitation, combustion, hydrothermal, forced hydrolysis and gel-templates methodologies will be elaborated in order to tune the size, morphology, structure and functionalization of the oxides materials. In these protocols, polysaccharides will be conditioned to act as: (i) stabilizers, (ii) templates (hard and soft), (iii) surface functionalizing agents and, (iv) carbon source. The developed synthetic approaches will use polysaccharides build up from D-glucose units linked by α- (starch, dextran) and β-glycosidic bonds (methyl-cellulose), with distinct polymerization degree, chain branching and rheological properties. ZnO, as well as ZnO/C and ZnO-polysaccharides composites of nanomeric sizes (50-300 Å) and various morphologies (including hierarchical and spherical structures as sphere, core/shell, hollow sphere, jingle-bell) and functionalizations are intended to be obtained. The assessment of a relationship with large degree of generalization between polysaccharide-synthesis-oxide represents benefits either from fundamental and applicative research points of view.

Abstract:

The main goal of the present proposal is to open a new interdisciplinary research direction and to build a team of experts in both fundamental and applicative research.

We aim to develop rational synthetic strategies leading to novel metallosupramolecular architectures with pre-established structures by linking homonuclear alkoxo-bridged Zn(II) nodes into lattices with polycarboxylate and/or divergent N-donor ligands. These will be further used for the preparation of nanosized ZnO materials. The physico-chemical properties of both precursors and ZnO particles will be investigated.

The interdisciplinary interaction of scientists with expertise in diverse areas (metallosupramolecular chemistry, synthesis of materials, materials characterization, and physics) will provide a better insight into the properties of the obtained systems.

Abstract:

The present proposal focuses on designing of a new generation of (supra)molecular heterotrimetallic magnetic materials. The main objectives of the project are:(i)obtaining of new heterotrimetallic molecular-based materials with modulated magneto-optical properties; (ii)achieving new physical properties which are intermediate between molecules and nanomaterials: these materials mark a crucial transition between molecular and nano-level;(iii) obtaining revolutionary multifunctional heterotrimetallic materials;(iv)developing of new theoretical models for understanding the magnetic properties of the obtained heterotrimetallic systems.The general method for the synthesis of complexes carrying three different metal ions is the self-assembly process between of pre-formed 3d-3d' and 3d-4f heterobimetallic units and suitable diamagnetic or paramagnetic metalloligands. The obtained compounds will be characterized by means of X-ray diffraction techniques on single-crystal and powder,magnetic measurements,various spectroscopic techniques according to their properties(FTIR, NIR-UV-Vis, fluorescence and circular dichroism) and elemental analysis.The project could be almost completely carried out in Romania due to the existent infrastructure.
