Abstract
Summary
The present thesis includes five main chapters: introduction, experimental, results and discussion, computational chemistry and application as well as list of used references, english and arabic summary. The main chapters can be summarized as:
Chapter (I):
This chapter includes an introduction for the literature survey of the previous work carried out on metal complexes derived from acetohydrazide, 3-formylchromone and thiophene-2-carbaldehyde and their derivatives, different methods for synthesis and different tools for characterization besides their applications.
Chapter (II):
This chapter involves a detailed account about the experimental procedures used in the present work: the used substances and solvents, the methods used for synthesis of hydrazone compounds and their binary and ternary complexes, the experimental tools to characterize the hydrazone ligands and their isolated complexes, the experimental techniques for electrospun method, electrical measurement, phenoxazinone synthase as well as antimicrobial and antitumor activities.
Chapter (III):
This chapter includes the results and discussion of hydrazone ligands and their complexes; it is subdivided into three parts:
1- The first part contained the results of studying the prepared hydrazone ligands with their discussion of analytical methods used for characterization.
2- The second part represented the results of studying the prepared solid complexes with their discussion and characterization by elemental analyses, IR, electronic, mass 1H NMR and ESR as well as magnetic susceptibility measurement, molar conductance and thermal gravimetric analysis.
According to the analytical data, the binary complexes have 1:1 stoichiometry (M : L) for complexes 1, 3, 11 and 14 and 1 : 2 (M : L) for the other complexes. For all mixed ligand complexes the metal ions reacted with the ligands and 8-HQ in the molar ratios 1 : 1 : 1 (M : L : 8-HQ).
All binary complexes have octahedral geometry except complexes 1, 3 and 11. Cu(II) complexes 1 and 11 have square planar geometry, while Ni(II) complex 3 has tetrahedral geometry. All the ternary complexes revealed an octahedral geometry.
3- The third part represented the results of studying the prepared nano solid complexes and electrospun fibers complexes with their discussion and surface morphology characterization.
Chapter (IV):
This chapter involves theoretical studies which represented in DFT calculations of optimized structures and calculated vibrational frequencies of the ligands and some selected complexes.
Chapter (V):
This chapter contains numbers of applications of prepared complexes; it is subdivided into five parts:
1- The first part concerned with the antimicrobial activity of the hydrazone ligands and their complexes in addition to the antitumor activity of CTA (HL2) ligand and its binary copper(II) complexes.
2- The second part represented the study of phenoxazinone synthase catalytic activity of prepared binary Cu(II) complexes and calculating Kinetic parameters of the oxidation of 2-aminophenole.
3- The third part involved the electrical properties of the ligands and some of their complexes whence dielectric constant and dielectric loss beside impedance.
4- The fourth part represented the effect of UV irradiation on the optical and electrical properties of prepared electrospun fibers complexes by exposure the thin films to UV lamps of 312 nm for one and two hour with the potency of detection the UV radiation..
5- The fifth part concerned with the photoluminescence study of bulk, nano and fiber Cu(II) and Zn(II) complexes in addition to the study of fiber complex 22 as fluorescent sensor for La(III) ion.
Finally, the thesis ends with list of references.
