Abstract:

Eight polymer-metal complexes were synthesized from complexation of divalent Mn(II), Ni(II), Co(II), and Cu(II) metal ions with modified polystyrene-alt-(maleic anhydride) (PSMAP and PSMAM) ligands. The structures of these new complexes were characterized using a variety of techniques, including magnetic moment susceptibility, conductance measurements, FT-IR spectroscopy, ultraviolet-visible (UV-VIS), thermogravimetric analysis (TGA), as well as scanning electron microscopy (SEM). All metal-polymer complexes have a non-electrolytic nature based on conductance measurements. The polymer molecule

Abstract:

A number of complexes of modified diamine (3,7-dimethyl-1,5-dithia-3,7-diazacyclooctane), were prepared with first row divalent transition metals, i.e., Cu(II) and Zn(II). The structures of these complexes were elucidated on the basis of various physical techniques such as mass spectrometry, NMR, IR, UV-Visible spectroscopies, magnetic and conductance measurements. Bioassay of these complexes has also been carried out. The physical measurements confirm distorted tetrahedral structure for these complexes.

Abstract:

The Co(II), Ni(II), Cu(II) and Zn(II) complexes with 8-hydroxyquinoline-5-sulfonylhydrazone are described. It has been found that the ligand can coordinate to metal ion as a monobasic bidentate chelating agent and it can form di- and trinuclear complexes while acting as a dibasic tetradentate one. The structure of the isolated complexes have been suggested on the basis of elemental analysis, IR, 1H NMR spectroscopy and conductivity measurements. The complexes are all formulated as four-coordinate. Some complexes showed enhanced antimicrobial activity relative to the free ligand.

This thesis presents electronic structure calculations on problems related to the bonding in inorganic coordination compounds and clusters. A wide range of molecules with the ability to exist in different structural forms or electronic states has been selected and density functional theory is systematically applied in order to gain detailed insight into their characteristics and reactivity at the electronic level. First, we address the question of redox non-innocent behaviour of bipyridine in a series of 1st row transition metal complexes. Complexes of the type [M(2,2'-bipyridine)(mes)₂]<sup>0

Abstract:

The structure of 25, 26, 27, 28-tetra(2-ethoxyaniline)calix[4]arene of cone (cL) and partial cone (pcL) conformations were optimized by PM3 of quantum chemical method. It has been found that cL structure is more stable than pcL conformation. The stabilization energies of protonation on four aniline-nitrogen atoms of both conformations of the ligand at 6-31G energy level, were obtained. The protonations process on the cL and pcL being 7 and 24 possible pathways, respectively, were evaluated. The basicity constants of partial cone conformation of 25, 26, 27, 28-tetra(2- ethoxyaniline)calix[4]are

Abstract:

In this research, a series of copper complexes containing polypyridyl ligands were designed to study the influence from ligands, nuclearity, solvents and secondary coordination on reactivity toward small-molecule activation. This structure-reactivity relationship was used in investigation for oxygen reduction reactions (ORR), and applied in detection of ascorbic acid (AsH₂). Firstly, copper (II) complexes containing polypyridyl derivatives ligands (i.e., Cu(dpa), Cu(adpa) and Cu₂ (addpa)) were synthesized and fully characterized by elemental analysis, mass spectrometry and X-ray crystallograph

Abstract:

Original objectives The general goal of the project was to utilize the bactericidal potential of curcumin- functionalizednanostructures (CFN) for reinforcement of food safety by developing active antimicrobial food-contact surfaces. In order to reach the goal, the following secondary tasks were pursued: (a) further enhancement of the CFN activity based on understanding their mode of action; (b) preparing efficient antimicrobial surfaces, investigating and optimizing their performance; (c) testing the efficacy of the antimicrobial surfaces in real food trials.
