Abstract:

The present research proposal aims to develop a series of directions which are less or non-explored to date in the chemistry of graphene. Its objectives rely on the experience of the four participants in organic synthesis, organometallic chemistry, molecular magnetism and catalysis. The project will stimulate not only the enhancement of the value of previously synthesized compounds by the partners, but also the development of an original chemistry. The hierarchical organization of organometallic – classical transition metal complexes on graphene surface is a step forward in materials science. The design of 3-D frameworks incorporating graphene is original and opens interesting perspectives for applications. The grafting of magnetic and luminescent complexes on graphene could bring an important added value in molecular magnetism. The catalytic processes to be investigated are carefully selected, in order to address important problems in organic synthesis, environmental protection and energy. The project will focus on the following major objectives: (i) design of networks by covalent connections between the decorated graphene sheets; (ii) design of graphene-based hybrid materials with appropriate organometallic/metalloid units as ligands for transition metals; (iii) single molecule magnets and luminescent molecules grafted on graphene; (iv) functionalization of graphene with macrocycles, cryptands and rotaxanes for organocatalytic reactions; (v) development of multifunctional catalysts for controlled cascade reactions; (v) applications in catalysis (the valorization of the CO2 emissions; the hydrogenation of nitro-alkenes and mixtures of acetylene-ethylene; C-C and C-N coupling reactions) and gas sorption. A special attention in these studies will be addressed to the investigation of the catalytic mechanisms.

Fluorescent materials based on fluorescein platform Call name: P 4 - Proiecte de Cercetare Exploratorie
PN-III-P4-ID-PCE-2016-0442 2017 - 2019

Role in this project:

Coordinating institution: UNIVERSITATEA BUCURESTI

Project partners: UNIVERSITATEA BUCURESTI (RO)

Affiliation: UNIVERSITATEA BUCURESTI (RO)

Project website: https://www.chimie.unibuc.ro/cercetare/anorganica/FluoMat/FluoMat.pdf

Abstract:

The current proposal is devoted to the design, synthesis, and characterization of novel fluorescent materials based on fluorescein platform. Three types of materials are targeted: i) discrete coordination compounds containing 3d or/and 4f metal ions and functionalized fluorescein based ligands; ii) coordination polymers containing 3d or/and 4f metal ions and fluorescein derivatives; and iii) hybrid organic solids constructed from functionalized fluorescein derivatives and other organic species through specific supramolecular interactions.

The project involves the following specific objectives:

1.Design and synthesis of functionalized fluorescein based ligands able to coordinate specifically to 3d and/or 4f metal ions; structural characterization of these ligands; investigation of the luminescent properties of the ligands; exploration of the sensing abilities of the functionalized fluorescein based ligands towards various metal ions.

2.Synthesis and structural characterization of mono- and binuclear complexes of the functionalized fluorescein based ligands with 3d metal ions and/or lanthanides ions; investigation of the luminescent and magnetic properties of the metallocomplexes.

3.Synthesis and structural characterization of coordination polymers using as building blocks mono- and binuclear complexes of the functionalized fluorescein based ligands with 3d metal ions and/or lanthanides(III) and various neutral and anionic spacers; synthesis and structural characterization of metal-organic frameworks (MOFs) with carboxylate derivatives of the fluorescein as spacers.

4.Investigation of the luminescent and magnetic properties of the coordination polymers.

5.Synthesis of hybrid organic solids by co-crystallization of functionalized fluorescein derivatives and other organic species using specific supramolecular interactions and investigation of the luminescent properties.

DESIGN OF ORGANIC SPACERS FOR CONSTRUCTING METAL-ORGANIC FRAMEWORKS (MOFs) – TOWARDS A BETTER CONTROL OF THE POROUS ARCHITECTURE AND ACTIVE CATALYTIC SITES Call name: Complex Exploratory Research Projects - PCCE-2011 call

Abstract:

The project aims to obtain a new generation of metal-organic frameworks (MOFs) using novel families of made-by-design spacers (Cyclophane and cyclophane-like spacers with pre-formed cavities; C3-symmetry cryptand-based ligands; Tetrahedral synthons; Organometallic spacers featuring robust metal-carbon bonds, e. g. Organometallic halides, with appropriate organic groups attached to the metal centre to provide stability of the organometallic unit and/or potential to develop 3D architectures. The efforts will be concentrated towards compounds with the metal in lower oxidation state bearing a lone pair of electrons and thus higher reactivity). The construction of MOFs using organometallic tectons is a field largely unexplored. A special emphasis will be given to the post-synthesis processing of the MOFs (removal of solvent and weakly coordinated ligands; functionalization of selected MOFs by nanoconfinement with metal nanoparticles and functionalization for generation of acidic and basic sites). The sorption of various gases (H2, CO2, C2H2, etc.) as well the catalytic properties of the newly synthesized MOFs will be investigated. Enantioselective organic reactions catalyzed by chiral MOFs will be studied as well. In this scope MOFs functionalized with acid and base functions will be investigated in the asymmetric aldol reaction between representative ketones with various aromatic aldehydes under solvent-free conditions. The luminescence properties of some MOFs as well as the influence of the host molecules on the luminescence (especially for those containing lanthanide cations) will be investigated. The ability of the new MOFs for decontamination processes will be tested - more specifically, MOFs will be used as adsorbents for the molecules resulted from the degradation of pharmaceutical compounds via either liquid phase catalytic oxidation or plasma.

Abstract:

The present project developes the synthesis and characterization of new chiral molecular systems based on amino-acids derivatives using the molecular approach strategy to produce compounds of interest in materials science .

New organic ligands (chiral tridentate Schiff base) will be synthesized in order to design new metals precursors with easily accessible basal positions that favor stronger interactions, and flexible coordination spheres. The ultimate goal of this project is to obtain complexes with interesting magnetic properties (molecular nanomagnets) and novel multifunctional materials combining magnetic properties with chirality and photomagnetic materials.

The molecular approach will allow a fine tuning of both the chirality and magnetic properties.

Using the tridentate ligands a new class of chiral heterodinuclear Ni(II)-Ln(III)systems will be design.

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.
