Abstract

The subprogramm is expected to develop optimal processes/methods for synthesis of about 10 to 15 new ligands containing O, S, N, P donor atoms and about 40-50 new coordination compounds of 3d- and 4f- transition metals and s-type metals with properties of potential adsorbents for small molecu-les, physiologically active substances, molecular magnets, specific catalysts for heterogeneous cata-lysis, nanostructured or highly porous materials. New coordination compounds of some 3d metals with N-(4-methoxyphenyl)-2-oxopropanamide, 1-(piperidin-1-yl)propane-1,2-dione, 1-(morpholin-4-yl)propane-1,2-dione, o/m/p-phthalic dialdehydes and 1-(azepan-1-yl)propane-1,2-dione 4-allyl/phenylthiosemicarbazones as potential antimicrobial, antifungal, antioxidant agents will be eaborated and studied. Coordination compounds of some 3d biometals with ligands containing thiosemicarbazones with different substituents in the 4N position: cyclohexyl, hexyl, tert-butyl /thiosemicarbazones of natural origin based on cinnamaldehyde and its derivatives with biological properties. The new coordination compounds will be characterized with adequate physical and physico-chemical methods of analyses (elemental analysis, X-ray , IR, NMR, RNG, ESR, UV-Vis, Magnetochemistry, Electronic microscopy, Ther-mogravimetry, Chro- mato-Mass-spectrometry, Ciclovoltammperometry, study of sorbtion proce-sses, etc.). This investigation will give the opportunity to: substantially clarify the role of the sinthe-sizedcomplexes in the fisiological, technological and biological processes; to publish and dissemi-nate the obtained scientific results in national and international journals; to present their at various scientific forums in the form of oral reports and posters; to recommend for certification and imple-mentation on the level from idea to implementation; to perform the intermediary and final reports of obtained results. Expected research are directly related to the strategic direction of the activity of science and innovation in Moldova, The National PROGRAM in the fields of research and innovation for the years 2024-2027.

Results, activities

Summary of the activity and results obtained in 2024

New porous coordination polymers of some s- and 3d-elements were obtained based on ligands containing carboxylic, triazole, pyrazole groups with nitrogen donor atoms, with permanent porosity, hydrolytically and thermally stable. They can be used as potential sorbents for gas storage and as catalysts in heterogeneous processes.
The synthesis of polynuclear complex combinations of some 3d metals based on ligands con-taining S, C, O, N and Schiff base donor atoms was carried out. They possess enhanced antibac-terial properties against bacteria and fungi, inhibitory properties of fungal proliferation in biolo-gical processes and can serve as potential catalysts for redox processes or as molecular magnets.
Synthesis methods of four new thiosemicarbazones with the abbreviation HL1-4 based on 4-allyl- and 4-phenylthiosemicarbazones N-(4-methoxyphenyl)-2-oxopropanamide and 1-(piperi-din-1-yl)propan-1,2-diones were developed. The molecular structure of which was confirmed by the help of spectral research methods (FTIR, NMR) and with of single crystal X-ray analysis.
For the first time, 36 coordination compounds of Cu, Co, Fe, Ni, Zn were synthesized on the basis of HL1-4. In order to elucidate the composition, structure and physico-chemical properties of the synthesized compounds, modern research methods were applied. The biological proper-ties: antimicrobial, antifungal, antioxidant of the synthesized compounds were investigated.
Phthalic acid dialdehydes upon condensation with monopyridinecarboxylic acid hydrazides form two types of chemical products: p- and m-dialdehydes with isonicotinic, nicotinic and picolinic acid hydrazides, in which two hydrazide molecules condense with one aldehyde group each, while in the case of o-dialdehyde, a hydrazide molecule of isonicotinic and nicotinic acids condenses with the two hydrazide nitrogen atoms, and the second molecule binds to the carbon atom of an aldehyde group.
It has been found that the main emission intensity for luminophore coordinating agents is concentrated in the 450 nm region of the visible spectrum and they can be proposed as a useful material for obtaining blue lighting sources.
In 2024, within the subprogramme, 2 monographs, 28 scientific articles were published in international, national journals, category A, B and various scientific collections. Team members participated in 14 international and national scientific conferences and published 46 abstracts, obtained 13 author patents. At the International Salons of Invention the patents were awarded with gold medals (30), silver medals (5), bronze medals (1) and 4 diplomas of excellence. 4 doctoral theses were defended.

Summary of the activity and results obtained in 2025

New methods for the synthesis of 3 Schiff bases and new coordination compounds based on salicylic acid derivatives were developed, the structure of which was determined using single-crystal X-ray diffraction.
Five porous metal-organic networks of 3d transition metals and f-type, with organic ligands containing carboxylic and phosphonic groups were synthesized. In order to elucidate the composition, structure and physicochemical properties of the synthesized compounds, modern research methods were applied (single-crystal X-ray diffraction, IR spectroscopy and elemental analysis).
Synthesis protocols for four new thiosemicarbazones with the abbreviation HL1-4 were developed based on the 4-allyl- and 4-phenylthiosemicarbazones 1-(morpholin-4-yl)propane-1,2-dione and 1-(azepan-1-yl)propane-1,2-dione. The molecular structure of the synthesized thiosemicarbazones was confirmed using spectral research methods (FTIR, NMR) and single-crystal X-ray analysis.
For the first time, 45 coordination compounds of Cu(II), Co(III), Fe(III), Ni(II), Zn(II) were synthesized based on HL1-4. In order to elucidate the composition, structure and physicochemical properties of the synthesized compounds, modern research methods were applied. To determine the therapeutic potential of the synthesized compounds, in vitro biological properties such as antimicrobial, antifungal, and antioxidant properties were investigated according to the specialized protocol.
Evaluation of optical properties by using the Theoretical Calculation of Density of States method confirms that the density of states values of the polymorph {[Cd(L)]∙0.5H2O}n compared to those of PC {[Cd(L)]∙H2O}n, in the range -3.0 ÷ 3.0 eV, are almost twice as high, and the DOS of Cd(II) atoms has a weak contribution in this range. Thus, the maximum of the FL spectrum of PC {[Cd(L)]∙0.5H2O}n is about 2 times higher compared to the intensity of the FL maximum of PC {[Cd(L)]∙H2O}n and for both claimed complexes the maximum of the FL emission intensity corresponds to the ligand-ligand charge transfer (π∙∙∙π*).
The emission spectrum profile of the polymers {[Cd(L)]∙0.5H2O}n and {[Cd(L)]∙H2O}n is characterized by fluorescent emissions in the yellow-green region (500-520 nm) of the visible spectrum, with the maximum located at 2.5 eV(500 nm) for {[Cd(L)]∙0.5H2O}n and 2.4 eV (520 nm) for {[Cd(L)]∙H2O}n, respectively. Thus, the claimed PCs exhibit photoluminescence suitable for manufacturers of displays and viewing devices, since the yellow-green region is the most comfortable and optimal for the human eye, which allows for better visual perception.
In 2025, within the subprogramme, 26 scientific articles were published in international, national journals, category A, B and various scientific collections. Team members participated in 16 international and national scientific conferences and published 30 abstracts, obtained 5 author patents. At the International Salons of Invention the patents were awarded with gold medals (25), silver medals (7), 2 special prizes and 4 diplomas of excellence. 1 doctoral thesis were defended.
