Abstract:

Tartaric acid, 4-hydroxymandelic acid and 3-(3,4-Dihydroxyphenyl)-L-alanine are organic compounds which upon polymerization under controlled conditions leads to formation of acidic polymers. Such multifunctionalyzed polymers are of interest due to their ability to coordinate to different metals and to form cross-linked frameworks. The role of the type of metal ion, the presence or absence of the solvent, the type of solvent and temperature, in the synthesis of these compounds will be identified. Due to the moderate solubility of chosen polymers the mechanochemistry (ball milling) and solvothermal methods will be used for their synthesis.

The formation of new complexes will be determined firstly by IR and XPS spectroscopy, X-ray powder diffraction (XRD), TEM, SEM/EDX measurements and electron paramagnetic resonance (EPR). Moreover, it will be attempted to get single crystals good enough for X-Ray diffraction. Also, a full theoretical investigation will be done for the obtained complexes to have a better understanding of the structure - properties relationship. Thermogravimetric analysis (TGA) and thermal conductivity of new complexes will be studied and compared with data obtained for non-complexed polymers.

These new complexes present interesting physical and chemical properties due to the presence of metal ions and the structure of the polymer like good thermal conductivity, elasticity, tunable porosity with further various applications.

Innovative COFs and hybrid metal@COF materials for smart applications: heterogeneous catalysis and Single Material Organic Solar Cells (SMOSCs) Call name: P 4 - Proiecte de cercetare exploratorie - PCE-2021

Abstract:

Covalent organic frameworks (COFs) emerged as promising porous, crystalline materials that found various many applications in various fields. The proposed project focuses on the obtaining and characterization of COFs and Metal@COF (Me@COF) hybrid materials designed for innovative applications in heterogenous catalysis, chiral separations and active materials in state-of-the-art Single Material Organic Solar Cells (SMOSCs). The strengths of the proposal rely on the careful design of the targeted materials. Therefore, versatile building blocks of various geometries are used to give access to a plethora of 3D achiral and chiral COFs and Me@COFs with modulable pore size to act as catalysts and asymmetric catalysts for various cross-coupling reactions. The main advantage of the proposed materials is the direct access to Me@COF hybrid materials by coupling reactions (i.e. Suzuki-Miyaura, Sonogashira, Glaser), thus incorporating in the COF structure the metal used as a catalyst in their synthesis. In addition, macrocycles- and cryptand-based COFs and Me@COFs bearing different types of cavities and catalytic site will be obtained and tested as multifunctional catalysts for reaction carried out sequentially or in cascade. Furthermore, taking advantage of highly ordered COFs structures we propose 2D frameworks that display efficient segregation of the donor and acceptor units, a requirement in the fabrication of highly efficient and stable SMOSCs.

Abstract:

The development of nanocomposites based on magnetic nanoparticles and fluorescent molecules is a fast growing research field in nanotechnology. These types of materials, however, possess some difficulties and challenges that need to be overcome, such as the quenching of the fluorescent entity by the magnetic core. That is why the coating systems have received a special importance by changing the hydrophilicity related with good dispensability or improving biocompatibility. As a coating, polydopamine fulfills these qualities being heavily investigated through both, in vivo and in vitro studies for many biomedical applications. But in terms of fluorescence this it is a breach of exploitation which is focused more on oxidation approached, degradation, conjugation, and carbonization of dopamine/polydopamine. In this project we propose a different approach by synthesizing new polydopamine analogues with extra heteroatoms in their structure. For this type of synthetic analogues we will systematically study the polymerization mechanism, adherence, and how the presence of N-type heteroatoms improves their fluorescence property. Coating the fluorescent new materials onto uniformly sized magnetic nanoparticles, fluorescent-magnetic nanocomposites will be engineered, which can serve as an all-in-one diagnostic and therapeutic tools with the additional advantage of being easy to control and monitor by fluorescent microscopy.

Abstract:

The project Renewable and green energy smart power supply systems for on-body sensors and handheld devices exhibits as main goal the development of new and innovative charging systems able to support the work of on body sensors and handheld devices. The target energy supply sources are Organic Solar Cells fabricated in the inverted cells technology which provides more robust and friendlier to manipulate devices. Many of the donors and acceptors envisaged to be used are compounds which were already obtained and investigated in our group (in usual OSCs). The target inverted OSCs use as support light and flexible materials which at the same time are eco-friendly and biocompatible. These materials are appropriate to the proposed applications, being possible their “quite” invisible attachment to clothes or small equipment’s and the total requested active surface is of few cm2. Besides the original work concerning the access to the OSCs which transform light in electric power a complex and original arsenal of miniature electronic devices must be produced in order to ensure the appropriate work of the entire power supply device. Several cells will be smartly connectedin an OSC Array (able to provide current at a given voltage). The output current obtained in the OSC Array will be modulated by a Charger System which will produce a current in appropriate parameters either for the charging of Li-ion or Li-po batteries which deserve a handheld device or for the charging of a supercapacitor (with role of battery) which deserve an on-body sensor. Another important device is the DC-DC convertor with role to modulate the current sent to the on-body sensor. All these electronic circuits will use microelectronics design and will be implemented on a thin flexible film coated with ITO as a PCB (printed circuit board) substrate. At the end of the project we will provide demonstrators to prove the viability of our work and we will record an evolution from TRL2 to TRL4.
