Abstract: تضمن البحث تحضير كاشفين جديدين هما الكاشف 3 - ((4,5 - diphenyl imidazole) diazenyl) benzene sulfonic acid ويرمز له (DPIDBSA) والكاشـــف2 - ((3 - methoxy phenyl) diazenyl) - 4,5 - diphenyl imidazole ويرمز له (MBDPI) وذلــــك من مفاعلة ملـح الديازونيـوم ل | This thesis included the preparation of the two new reagents 3 - ((4,5 - diphenyl imidazole) diazenyl) benzene sulfonic acid (DPIDBSA) and 2 - ((3 - methoxy phenyl) diazenyl) - 4,5 - diphenyl imidazole (MBDPI) by reacting adiazonium salt solution of (3 - aminobenzene sulfonic acid) and (3 - methoxyaniline) with (4,5 - diphenyl imidazole) in alkaline ethanoic Solution.The identity of these reagents have been characterized by spectral methods such as(UV - Vis) , FTIR , another physical properties (m.p.) and elemental analysis.The ionization constant of the reagent (DPIDBSA) was determine using spectroscopic method , the pKa was equal to 9.9.Six chelating complexes of the above reagents were synthesized with metal ions) Co2+, Ni2+, Cu2+). 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).

Four derivatives of the theophylline where these are SAT , BAT , 4NAT , 3NAT these derivatives were used as ligand because of is abitity to from helating complex , these derivatives were reacted with eight metal ions these are (Fe2+, Co2+, Ni2+, Cu2+, Zn2+, La3+, Ce3+) these complex were characterized by many methods as molarratio, measuring of electrical conductivity electronic spectra , which helped us to find the chemical structure of those complex this study also found that ratio of ligand metal was 2 : 1 this study also include the study of biological effect for these ligand and complexes on four deferent pathogenic species (staphylococcus aureus, streptococcus viridans ) ,(protens vulgaris, pseudomonas aeruginosa ) the two first species are gram positive while the other are gram negative , finally (by using disk diffusion method) it was found that these compounds show different activity of inhibition on other growth of the Becteria.

Abstract: تضمنت الرسالة ثلاثة فصول. يحتوي الفصل الاول على مقدمة لنبذة تاريخية للمواد البلورية السائلة وصفاتها الفيزيائية وبعض الامثلة لتطبيقاتها,وكذلك الخصائص الثرموديناميكية للمزيج الثنائي والثلاثي للمركبات البلورية السائلة. وتحتوي المقدمة ايضا على شرح مختصر لتق | This thesis consisted of three chapters. 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.
