| Abstract | ||
| The bis (P-substituted-2-methoxy aniline benzilidine-4-oxy) octamethane was prepared used as a donor to form 1:2 complexes with 2,3-dichloro-5,6-dicyanobenzenquinone (DDQ), respectively. The equilibrium constants (K), molar absorptivity extinction coefficients ( ) and the dissociation energies of the charge transfer complexes excited states (w) have been calculated and discussed. The ionization potentials of Schiff bases have been determined and has been concluded that these complexes are predominantly of the n type. الملخص حضر المركب بس (بارا-معوض-2-ميثوكسي أنيلين بنزلدين-4-أوكسي) أوكتاميثان وأستخدم كمانح للإلكترونات ليعطي المعقد 2:1 مع 3,2-ثنائي كلورو-6,5-سيانوبنزوكوينون (DDQ) . وتم حساب ثوابت التوازن (K) ومعاملات الامتصاص المولاري ) ( وطاقات الحالة المثارة (w) لمعقدات انتقال الشحنة كما تم حساب جهد التأين لقاعدة شف وللمعقدات المحضرة وأستنتج أن هذه المعقدات تظهر أنتقال من نوع n . | ||
