المستخلص: تتضمن الدراسة عدة اجزاء : الجزء الاول : تحضير مجموعة من قواعد شف من تكثيف البنزلديهايدالمعوض بالمواقع بارا بمجاميع( بارا - برومو، بارا - كلورو، بارا - نايترو، بارا - N,N - ثنائي مثيل امينو بنزالديهايد ) مع معوضات الانلين المختلفة (بارا - امينو اسيتوفينو | This Work was accomplished through the following four part : Part one In this part nine Schiff bases derived from p - substituted benzaldehyde) with (p - bromo aniline , p - amino acetophenon, aniline, 2 - amino phenol were prepared.The electronic spectra in absolute ethanol solution were used to study the intermolecular charge - transfer complexes between the considered Schiff bases as charge donor , and iodine as charge acceptor molecules.The physical parameters of charge - transfer complexes were calculated by applying Bensi - Hildebrand equation. The equilibrium Constants for complexes formation were found to follow (3<4<9<6<7<8<5<1<2) arrangement. The energy of the complexes and extiztion coefficient were found to have the same arrangement shown above. The difference in the values of this physical properties are attributed to structural difference of the molecular (donating and withdrawing substituted groups). KCT values for the complexes were calculated from Bensi - Hildebrand equation and was found to fit the following arrangement ( 9<8<7<4<3<6<5<1<2 ), depending mainly on the types of substituted groups on aniline ring. Part Two Effect of temperature variation on equilibrium constant for the charge - transfer complexes formation were measured by applying Bensi - Hildebrand equation ,which used to estimate the thermodynamic parameter such as (?G0, ?S0 , ?H ) in absolute ethanol. Part Three The kinetic of the formation of charge - transfer complexes in absolute ethanol was studied.The results indicated that, the more stable charge - transfer complexes have higher rate constant formation and the kinetic of CTC was first order. Part Four Photo stability of (1 - 9) Schiff bases against direct sun light was investigated as solution in both ethanol and dimethyl sulfoxide DMSO.The results indicated that, the rates of photo decay of the Schiff bases in ethanol were faster than in DMSO solvent and the photo decay kinetic was found to follow first order reaction in ethanol and second order in DMSO solution.

The two wavelength of maximum absorption for the two reagents were found (422nm) and (416nm) respectively in ethanol and for the complexes formed between these ions with these reagents were found at (476, 492, 504nm) and (455, 458, 496nm) for cobalt(II) , nickel(II) and copper(II) respectively in aqueous medium.It has been prepared after fixing the optimum condition of concentration and acidity function, through the study of UV - Vis spectrum for reacting of metal solution and two reagents solution. For wide range of pH (5 - 11) and concentration which obey to Beer - Lambert Law.The structures were determine according to the mole ratio method and continuous variation method which is obtained from the spectroscopic studies of the complex solutions. The ratios of (metal : reagent) are equal to (1 : 2) for all the complexes ions.The stability of complexes in the solutions was also studied at the optimum conditions.Diagnosis the solid prepared complexes by UV - Vis spectrum in ethanol solution showed high chromic shift from as compared with free reagents in visible region to all the complexes prepared.Micro elemental analysis for all the complexes were prepared and the percentage of Co(II) and Cu(II) were determined , using flame atomic absorption spectroscopy, it was noticed a great accord between theoretical and particle ratio.The infrared spectrum of chelating complexes also studied and it's compared with the two reagents spectrum. They give notice change with free two reagents spectrum. These showed new bands that were not found original in two reagents spectra but other bands have been changed in shape, in trinity and location. This may indicate that a coordination between the metal ions and the two reagents prepared.The Conductivity measurements for solutions at (1×10 - 3M) in ethanol solution have shown non - ionic character for all chelate complexes.From the above observations, it's suggested stereo shapes for complexes, that show the two reagents (DPIDBSA) and (MBDPI) behave as bidentit reagent, we can conclude that the proposed geometrical structure of all chelate complexes are octahedral.The study also included using spectrum method for determination stability constant of complexes in the thermal rang (25 - 45C?) for complexes with reagent (DPIDBSA) while the thermal rang was (10 - 30 C?) for complexes with reagent (MBDPI), and calculating ?G , ?H and ?S for complexes.The bacterial activity of the ligand and it's complexes were studied toward two type of bacteria : 1 - Pseudomonas. aurginosa 2 - StaphylloCoccus. aureusThe complex of Ni(II) with reagent (DPIDBSA) and the complexes of Co(II), Ni(II) and Cu(II) with reagent (MBDPI) and metal ions solution showed high bacterial activity on Pseudomonas. aurginosa while the solution of two reagents and all chelate complexes prepared also the aqueous solution of metal ions don't showed any activity toward the two type of bacteria (StaphylloCoccus. aureus) (G+ve).

First chapter contained an introduction to explain the historical view, physical properties, application and thermodynamic characterization of binary and tertiary system mixtures of liquid crystalline materials. Also it contained an introduction to Nanotechnology and nanosheets like graphene oxide and its functionalization and a summary about the dielectric permittivity and conductivity. The second chapter explained the experimental part including the synthesis of graphene oxide (GO) and its functionalization and general synthesis procedure of eight liquid crystalline compounds, which were outlined as follows : 1. N1,N4 - Bis(4 - subst. - benzylidene) benzene - 1,4 - diamine [3a - d] 2. N4,N4? - Bis(4 - subst. - benylidene) biphenyl - 4,4' - diamine [5a,b] 3. 3,3' - dimethyl - N4,N4? - Bis(4 - subst. - benzylidene)biphenyl - 4,4' - diamine [7a,b] The binary mixtures were prepared from a non - polar compound N1,N4 - bis(4 - methylbenzylidene) benzene - 1,4 - diamine and N1,N4 - bis(4 - bromobenzylidene) benzene - 1,4 - diamine as polar compound. The tertiary mixtures were prepared by mixing the mole fraction of the eutectic point (60%A) mixture [D] from the binary system and considered as the first compound A, the second compound was 3,3' - dimethyl - N4,N4? - bis(4 - bromobenzylidene)biphenyl - 4,4' - diamine as compound B.The tertiary system mixture at (13%B) showed the lower eutectic point, each concentration of the eutectic points in the binary and tertiary systems was mixed with graphene oxide and graphene oxide functionalized with polyaniline. The third chapter described the characterization of the prepared GO nanosheets with different functional groups.These nanosheets were characterized with multiple techniques (FT - IR , X - ray diffraction, SEM and AFM). The prepared liquid crystalline compounds were characterized by using FT - IR infrared and the liquid crystalline properties of compounds [3a - d], [5a,b],[7a,b] , the binary, tertiary systems and the mixtures with graphene oxide (GO) and GO functionalized nanosheets were examined with hot - stage polarizing microscopy, at the concentrations of the eutectic points , measured the dielectric permittivity and conductivity ?ac at the concentrations of the eutectic points. The addition of the nanosheets caused lowering of the transition temperatures of eutectic points in the binary and tertiary systems. It is worth noting, that in the two mixtures was appeared a new unknown (enantiotropic smectic ) phase.
